In the process of China's transformation from a big iron and steel country to a strong iron and steel country, Baotou Steel is willing to make friends all over the world with the unique enthusiasm and openness of the grassland and create a better future. Second, the internship content 1, Baogang Steel Plant165438+1On October 5th, we visited the steel plant.
The steelmaking plant of Baotou Steel is one of the important secondary plants under Baotou Steel, which not only produces the steel needed by various markets, but also undertakes the task of providing raw material blanks for other secondary factories and mines of Baotou Steel. After entering the workshop, we climbed the stairs and saw two large converters. Baotou Steel has two converters with 265,438+00 tons. 2 10 converter steelmaking project is the key construction project in the Ninth Five-Year Plan, and it is the supporting project of thin slab continuous casting and rolling project in Baotou Steel. It undertakes the task of providing high-quality molten steel for the new thin slab continuous casting and rolling production line of Baotou Steel.
According to reports, the converter equipment used in the project is American equipment introduced by Shougang for the construction of Shandong Qilu Iron and Steel Company in 1994, which was transferred to Baotou Steel due to the cancellation of the Shandong project. The converter of Baotou Steel is a set of high-tech converter equipment, and the dry dust removal project of Baotou Steel's converter has obvious energy-saving and environmental protection effects, which makes the circular economy construction of Baotou Steel step to a new level.
When Baotou Steel Sheet Plant was completed and put into operation, wet dust removal was adopted in the steelmaking process. With the increasing awareness of environmental protection in the international steel industry and enterprises, the weaknesses of high energy consumption and unsatisfactory environmental protection effect of wet dust removal are gradually exposed and gradually replaced by mature dry dust removal technology. Baotou Steel Steelmaking Plant was established in 1954. Initially, experts and technology were introduced from the former Soviet Union, with three open hearth furnaces and three converters.
At the end of 2000, the factory stopped the last open hearth steelmaking. Three years ago, all open hearth furnaces were dismantled and all steelmaking was made by converter. At present, there are seven converters.
5 continuous casting machines. At present, the main steel products are: heavy rail steel, oil casing steel and so on.
The main casting blanks are: bloom, round billet, small billet and round billet. In addition to continuous casting, molten steel is also partially cast according to customers or actual needs. The principle of steelmaking is that excess carbon and other impurities contained in pig iron are converted into gas or slag by oxygen or iron oxide at high temperature and removed.
The essence of pig iron smelting into steel is to appropriately reduce the carbon content in pig iron, remove most harmful impurities such as sulfur and phosphorus, and adjust the content of alloying elements in steel to a specified range. The main reaction principle of steelmaking is also to use oxidation-reduction reaction at high temperature.

Practice report of ironmaking and steelmaking plant
On July 17, 2005, five students from metallurgical class 034 took a train to Baotou Group Company in Baotou, Inner Mongolia. Everyone is very happy and excited. At first, they almost laughed and ate while walking.
On the morning of June 8th, around 1 1, we arrived at Baotou West Railway Station successfully, and found him under the guidance of alumni, and found him for us in advance.
Good hotel-the third guest house for Baotou Steel workers.
On June 9, 65438, the observation and internship interview of Baotou Steel was officially started.
First, we visited the steel-making plant of Baotou Steel. 19 at 8 o'clock in the morning, a van sent by Baotou Steel Ironmaking Plant took us to Baotou Steel Steelmaking Plant. According to the previous contact, we first found the director of the steel mill and our alumnus, Director Hao Zhizhong. Unfortunately, it happened. At this time, Baotou Steel Group Corporation is carrying out educational activities to maintain the advanced nature of Communist party member, and the leaders are as busy as a bee. So our activities were arranged by Director Hao for the factory director.
Under the arrangement of Director Qi, we first visited the blast furnace operation in the Third Steelmaking Plant of Baotou Steel. When visiting and interviewing workers in Baotou Steel, we learned that there are four blast furnaces with 7426 cubic meters in Baotou Steel. Among them, No.4 blast furnace is a modern large-scale blast furnace newly built in 1990s, and its safety and steel output are very advanced. Its diameter is about10.5m, and it is tapped about 18 times a day. Although it is not the most advanced in the world, it is of great significance to all aspects of Baotou Steel.
Leaving the noisy and sultry blast furnace of the ironmaking plant, we walked to the main control room in the south of the blast furnace. As soon as I entered the master control room, I felt a cool and comfortable feeling of escaping from the fire. The master worker who led the team quickly brought each of us a bottle of mineral water and sat next to the computer drinking cold water and looking at the monitor, only to know how hard the master worker outside a wall was. On a hot summer day, standing next to a blast furnace with a high temperature of several thousand degrees, although the temperature outside the furnace is far less than that inside, it is really unbearable for people. However, the workers and masters inside are drinking water, enjoying the coolness of the air conditioner and sitting next to the machine. In contrast, "technology is the primary productive force" is indeed correct. On second thought, the burden on our contemporary college students, especially those from the School of Metallurgy and Ecological Engineering, University of Science and Technology Beijing, is really not light. We must not live up to the glorious title of Metallurgical Institute, not to mention our alma mater, Beijing Institute of Iron and Steel, which has trained steel heroes for more than 50 years and is known as the cradle of steel.
Next, we went to main control room. Here, we interviewed a master worker from Chongqing. He came to Baotou Steel two years ago. According to him, after two years of training practice, he has a comprehensive understanding of the operation mode of Baotou Steel's steelmaking plant and his work is much easier. Of course, this is due to the help and teaching of the old worker master at the beginning of entering the factory. The next day, on July 20th, we set foot on Baotou Steel again. This day I mainly went to the sintering workshop and the coal supply workshop. Here, Master Zhang leads us all the way from the coal storage workshop to the grinding workshop of the ball mill and then to the main control room. We are not interested in other things, but we are interested in ball mills. Because we heard the teacher say that our mechanical drawing practice during the holiday was drawing ball mills, everyone was very excited. The imaginary thing is in front of you at this time. Be sure to have a good look, and it will be good to paint when you go back to your internship.
It rained all day on July 2 1.
On the fourth day, July 22nd, the rain stopped. We walked into Baotou Steel for the third time and began a visit and interview to the steel-making plant of Baotou Steel. At this time, for Beijing in July, it may be a scorching sun, but the summer heat in Baotou, thousands of miles away, is dissipating day by day. Five members of our internship group at Baotou Steel came to Baotou Steel Steelmaking Plant. After visiting the steel plant for two days, everyone felt very tired. However, when we think of the hard-won internship opportunities, we all have a spirit of twelve points. These days, Master Wang, a worker in the No.1 Ironmaking Plant, put down his work and accompanied us to visit No.4 blast furnace in the scorching sun, patiently and meticulously guiding us. Because we are only sophomores with limited professional knowledge, there are always endless questions. The master has no boring meaning at all, and has been answering questions. Director Hao of Baotou Steel Ironmaking Plant is an alumnus of University of Science and Technology Beijing, and the days we went were just an educational activity to maintain the advanced nature of Baotou Steel. Director Hao can also help us to contact the steel plant of Baotou Steel in detail during his busy schedule. It was not until later that I realized that thanks to their contact and communication, if we rushed forward, we would certainly not be able to complete the task even if we were not rejected. Through this experience, we can at least understand that the atmosphere and environment of campus and enterprise are so different. It also allows us young students who are about to enter the society to prepare a vivid social material in advance.
On July 23rd, 2005, we interviewed the members of Foreign Trade Personnel Department of Baotou Steel Group.
Fourthly, discuss the development of industrialization in China. Realizing industrialization has always been the clear goal of China Revolution led by * * *.
After the task of restoring the national economy in the early days of the founding of the People's Republic of China was completed, * * * and the CPC Central Committee promptly put the historical task of realizing industrialization on the central agenda and set out to deploy and plan the blueprint for national industrialization. This is mainly reflected in the proposal of 1952 "general route for the transition period" and the formulation of 1953 "five-year plan" for the first national construction.
The basic content of the party's general line in the transitional period is to gradually realize the socialist industrialization of the country and the socialist transformation of agriculture, rival industries and capitalist industry and commerce. (referred to as "one change and three changes". )
Its main body is to rapidly develop productive forces and realize socialist industrialization. 1, the first five-year plan was a complete success. Starting from the lazy situation at that time, the main task of the first five-year plan (1953- 1958) was to concentrate on developing industries, especially heavy industries: metallurgy, fuel, electric power, machine building, chemical industry, etc.
It is planned that within five years, the total national investment will be 76.64 billion yuan (equivalent to more than 700 million taels of gold), of which 58.2% will be used for industrial capital construction, building a number of new industrial sectors with huge scale and advanced technology, and expanding and transforming the original industrial sectors with modern advanced technology. On the one hand, it is necessary to rationally utilize and transform the existing industrial bases in coastal cities such as Northeast China and Shanghai, and on the other hand, it is necessary to start building a number of new industrial bases in the Mainland, so as to greatly improve China's industrial production capacity and gradually improve the unreasonable distribution of productive forces.
While giving priority to the development of heavy industry, we should pay attention to overall planning, balanced and coordinated development, and develop agriculture, transportation, light industry, posts and telecommunications, commerce, culture and education accordingly. As * * * announced in the opening speech of the First National People's Congress in September, 1954: "We will build an economically and culturally backward country into a great industrialized country with a high degree of modernization within several five-year plans."
(Selected Works of * * * Volume V, page 133. Under the correct leadership and deployment of Chairman Mao and the Central Committee of the Communist Party of China, and with the great assistance of the Soviet Union, the objectives and tasks of China's first five-year plan were successfully completed one year ahead of schedule.
During the First Five-Year Plan period, the total investment in capital construction in China was 58.8 billion yuan, focusing on 156 large projects, and 694 industrial and mining construction projects above designated size were built. By the end of 1957, 428 units had all been put into production, and 109 units were partially put into production.
Fixed assets increased by 49.2 billion yuan, 0.9 times that of 1.952. Among them, there are many large-scale projects, such as: the three major projects of Angang-large steel rolling plant, seamless steel pipe plant and No.7 iron refining furnace started production; Newly-built joint ventures of Masteel, Baotou Steel and WISCO; China No.1 Automobile Factory (Changchun) was completed and began to produce "Jiefang" brand cars; The first tractor factory in China (Luoyang) was built; The first aircraft factory established and successfully trial-produced the first jet; The first machine tool plant (Shenyang) was completed and put into operation; The first modern electron tube factory (Beijing) was completed and put into operation; The first modern comprehensive factory for manufacturing radio components-North China Radio Equipment Factory was put into operation; ——Xi 'an No.2 Power Plant, the first large-scale power plant in northwest China, was completed; Yumen Oil Mine, the first natural oil base, was built.
Wuhan Yangtze River Bridge and Hengyang Xiangjiang Bridge were completed and opened to traffic, and Qinghai-Tibet, Kangzang and Xinzang highways were completed and opened to traffic during the First Five-Year Plan period. These constructions have not only filled the gaps in some modern industries, but also carried out technological transformation on some old industries, which has significantly improved the industrial base and production capacity of China.
There are many important industrial products, such as generators, metallurgical and mining equipment, the latest metal cutting machine tools, automobiles, jets and so on. It could not be manufactured before, but it can be produced at this time. At the same time, because most of the projects and investments are invested in the mainland, (for example, Wuhan Iron and Steel Plant, Wuhan Heavy Machine Tool Plant, Wuhan Boiler Plant, Wuchang Shipyard, Wuhan Meat Processing Plant and other large enterprises have been established in Wuhan alone), which has played a great role in changing the unreasonable layout of old China's industries that were excessively biased towards the coast.
By 1957, the national total industrial output value reached 70.4 billion yuan, an increase of 1952/28.3%, with an average annual growth of 18%. Output of main industrial products: 5.35 million tons of steel, up 296% compared with 1952, 5.8 times the highest annual output before the founding of the People's Republic of China; The coal output reached1.300 million tons, an increase of 96% over 1.952, which was 2. 1 times the highest annual output before the founding of the People's Republic of China. The power generation reached193.4 billion kwh, an increase of 1952/66%, which was 3.2 times of the highest annual output before the founding of the People's Republic of China. 6.86 million tons of cement, an increase of 65.438+0.40% over 65.438+0.952.
Most indicators were completed ahead of schedule and exceeded. The achievements of the first five-year plan not only strongly proved the scientific correctness of the party's general line and planned economy during the transition period, but also fully demonstrated the outstanding ability and superb efficiency of * * * in leading economic construction, especially industrial development.
The Great Leap Forward Movement achieved great success. With the early completion of the first five-year plan, Chairman Mao decided to further accelerate the pace of construction and development. Therefore, the call of "Great Leap Forward in Production" was issued.
1958 1 He said: "China's backward economy and weak material foundation make us still in a passive state, and we still feel bound mentally. In this regard, we have not been liberated. You have to drum up. "
Now we need a technological revolution to catch up with and surpass Britain in fifteen years or a little longer. (Selected Works of Mao Zedong, Volume 7, p. 350th. )
"To set off a production and construction * * *". Although there were many mistakes in the Great Leap Forward Movement, its important position and great achievements in the history of China's industrial development are undeniable.
For industrial construction, the Great Leap Forward achieved what people now call "extraordinary" and "leap-forward development". Many major projects, major construction projects and major scientific and technological achievements were implemented and achieved in the Great Leap Forward.
For example, in the iron and steel industry, there were not only Wuhan Iron and Steel Plant, the largest steel plant in China at that time, but also Handan Iron and Steel Plant, Jinan Iron and Steel Plant, Hangzhou Iron and Steel Plant, Guangzhou Iron and Steel Plant, Nanjing Iron and Steel Plant and Anyang Iron and Steel Plant.

Sixth, after visiting Baotou Brewery, we were curious and excited, and we couldn't wait to rush in. The aunt in charge of reception led us into the hall. In order to let us know more about the brewery, we first watched a three-minute information video. From here, I learned the development history of the brewery: Baotou Xue Lu was founded in 198 1 and was acquired by Beijing Yanjing Group in 2000. The previous annual sales volume was1.200 million tons, and now the annual sales volume is 600 million tons. I also know that beer is made from mineral water, barley and hops imported from Australia.
Knowing the production technology of beer, we came to the production workshop again and experienced the production process of beer with our own eyes. We went to the "malt workshop" first, and then to the saccharification workshop. There are gelatinizing pots and boiling pots, where the wheat paste produced by malt workshop is made into wine. Finally, we came to the packaging workshop. It's amazing to see those beer bottles without lids enter a machine like a boiler and come out with lids! Each machine can hold 10 bottles of beer in one second and can produce 36,000 bottles of beer per hour.
The enthusiastic manager also gave us a non-alcoholic beer. I drank two glasses of pineapple, which was really delicious. After visiting the brewery, we took a group photo in front of the brewery and left a good memory.
I'll still walk when I come back. Although it was cold, I gained knowledge and happiness. We're really glad you came!
7. Who can help me find out which steel mills are in which city in China? 1. Abe Steel Base.
Including Anshan Iron and Steel Company and Benxi Iron and Steel Company. Located in the central industrial zone of Liaoning, it is adjacent to Qian Shan Mountains in the east, Taizi River, a tributary of Liaohe River in the north, Qianli Plain on both sides and Bohai Bay in the south. The distance between Anshan and Benxi Iron and Steel Company is only 10O km. The surrounding resources are abundant, and the proven reserves of iron ore are nearly 100 billion tons, of which industrial reserve has more than 4 billion tons, ranking first among the major bases. The existing iron ore mining capacity is about 40 million tons, making it the largest iron ore base in China. 1990 the output of iron ore (raw ore) reached more than 38 million tons, accounting for more than 50% of the total iron ore output in China.
