Compared with the manufacturing processes of various fiber materials, it can be seen that the biggest difference between the folding mould lining of Jinshi aluminum silicate fiber and the fiber spraying lining is that the mould lining is made by dry method, which does not contain any adhesive, and the anchorage is far away from the working hot surface, which does not form a "thermal bridge", which has low requirements on the material of the anchorage and better thermal insulation effect.
Performance characteristics of fiber module furnace lining;
GoldSi Tong aluminum silicate fiber module furnace lining is a kind of all-fiber furnace lining structure. The refractory fiber blanket is folded into an organ shape according to a certain width, then pre-pressed to a certain amount, bound under pressure, and anchored at the same time, and then fixed by bolts welded on the furnace wallboard. Its specific features are as follows:
1) The lining of refractory fiber module is completely fixed on the cold surface, and the anchoring is far away from the working heat, which can save anchoring materials and reduce the project cost to a certain extent.
2) Simple construction and short period: the lining of refractory fiber module is elastic, and the compression amount can be predicted. Therefore, there is no need to leave expansion joints during construction, and the construction personnel can take up their posts after basic training. The construction technical factors have little influence on the lining insulation effect.
3) There is no need for drying and curing after construction: the lining of the refractory fiber folding module can be quickly heated to the process temperature after construction without being limited by other metal components, which effectively improves the effective utilization rate of the industrial furnace, thus reducing the fuel consumption during non-production.
4) Thermal shock resistance: The refractory fiber module lining has excellent resistance to severe temperature fluctuation, and the fiber lining can be heated or cooled at any fast speed on the premise that the heated part can bear it.
5) Mechanical impact resistance: the fiber blanket has flexibility and elasticity, and after being processed into a folding module, it has greater integrity and strength and is not easy to be damaged. When the installed integrated furnace is impacted or vibrated by road transportation,
Not easy to be damaged.
Advantages of fiber module lining structure;
1. The anchor nail for the module is located on the cold surface of the lining (about 50 mm away from the steel plate) and far away from the hot surface, which not only reduces the formation of thermal bridge between the furnace gas and the furnace wall plate, but also reduces the grade of the anchor material, thus reducing the construction cost.
2. The fiber structure has good integrity, low thermal conductivity, good overall thermal insulation effect, low fiber packing density, low load on the whole steel structure, and the module does not contain adhesive, so it will not react with flue gas to generate harmful gas during use, which can effectively protect the steel plate.
3. The module itself contains no water, so it can be put into production without baking after construction, which shortens the production cycle.
4. Simple construction and short period: the lining of refractory fiber module is elastic and the compression can be predicted. Therefore, there is no need to leave expansion joints during construction, and the construction personnel can take up their posts after basic training. The construction technical factors have little influence on the lining insulation effect.
