|
fireclay refractory castable or mortar |
widely used for the lining of heating furnacesoaking furnace and so on.
High Performance Refractory Castable
It is made of high grade refractory raw material and effective compound binder,posses good flowability,high serving temperature,low permanent linear change,high strength.
Mainly used for the inner lining of the thermal furnace and kiln,such as heating furnace,soaking pits ,etc.
