Many people do not know how to use refractory castable during construction, which leads to waste of materials. The following staff will teach you how to use refractory castable?

 

How to use the refractory castable?

1. The refractory castable does not support the mold, and the refractory castable is applied manually. This situation is generally used in the construction of the lining of the blanking pipe, and sometimes even occurs in the construction of the lining of some preheater cones.

2. In winter construction, salt or other substances are added as antifreeze, which reduces the high-temperature performance of the material, or reasonable antifreeze measures are not taken during construction in winter.

3. In order to pursue the construction speed, the amount of water added to the refractory castable can be increased arbitrarily. The mixed refractory castable can be transported into the mold with a rubber hose several meters or even ten meters long like water.

4. Molding: It is made of steel plate or hardwood board.

5. Stirring: Using a forced mixer, first pour the refractory castable into the machine, take out the additive sachet and pour it together, dry mix for 2-3 minutes, add water for wet mixing for 3-5 minutes, add less water and not more, add Water volume 7.0-7.5%.
