Introduction of Silicon Carbide Sic Castable
Silicon Carbide Sic Castable is a kind of unshaped refractory material. The main component is silicon carbide. Generally, 98 silicon carbide is used as aggregate and fine powder, and binders and additives are added. After stirring, it can also be made according to the use environment and process. In other cases, choose to add explosion-proof fiber, corundum, bauxite, mullite and other materials to improve the performance of silicon carbide castables or make composite silicon carbide materials. Silicon Carbide Sic Castables need to be waterproof and moisture-proof during storage to avoid material failure. When using it, you can calculate the usage amount first, dry mix it in the mixer for 5 minutes, and then add a certain amount of clean water to stir. After mixing evenly It can be used for construction, and the mixed material should be used up as much as possible at one time. If the construction time is long and the remaining materials are not used up, try not to continue to use it, which will affect the construction quality and thus affect the use effect of the product.
