Cracks in the castable inside the boiler are a very dangerous phenomenon, which must be dealt with in time to avoid accidents. The causes of cracks are as follows:

1. The construction technology is unreasonable.

For example, the "ash-water ratio" of castable is not well controlled in the mixing process. Too much water is added, and the stirring time and vibration time are not well controlled.

The demoulding time, castable curing time and baking quality are not well controlled.

Second, the structural design is unreasonable and the quality of castable is poor.

For example, the expansion joint design of refractory and wear-resistant materials is unreasonable.

Three: the quality of refractory and wear-resistant materials is not up to standard.

For example, the matching and combination of aggregate and matrix of wear-resistant materials has an important influence on the wear resistance of materials.

These factors are the causes of cracks in castable materials inside the boiler.
