Characteristics of magnesium siliceous refractory castables

Magnesia-silica refractory castables include castables in the forsterite configuration and castables configured with magnesia and silica fume. Castables formulated with magnesium oxide and silica ultrafine powder have the advantages of good construction performance and low water consumption.

When 12% silicon powder is added to the castable, a castable with minimal residual shrinkage can be obtained. As the amount of silica added increases, the degree of erosion of the slag on the castable tends to increase, and the penetration depth of the slag tends to decrease.
