Corundum Refractory Castable is made of corundum, super high alumina clinker and silicon carbide as main material, compositing binder, water reducing agent, dispersant, etc. The product has high wear resistance, erosion resistance, erosion resistance.
Corundum Self-flow Refractory Castable Application：
Corundum refractory castables, used in joint of gas purge plug and nozzle seating brick, can produce micro-expansion in high temperature, which avoids leaking steel and accidents around the seating brick, as well as protects the seating brick and extent the service life of seating brick.
Corundum Refractory Castable Advantages：
This product can save labor and conduction machine because of its simple conduction and filling the gap below the level with the help of self-gravity.
