Refractory Castable High Strength Wear Resistant Castable with Sic

Feature For High strength wear resistant castable :

Silicon carbide as refractory raw materials have the following process characteristics:

1, Good thermal shock resistance, can withstand rapid changes in temperature, to prevent cracks or cracks lining.

2, Good wear resistance, at a certain temperature, can be used as wear-resistant lining.

3, Can withstand the role of some furnace gas, can be used for atmosphere furnace.
