Product introduction of lable refractory castable
The ladle refractory castable is made of high quality bauxite, corundum and high quality magnesia as main materials. It is a kind of amorphous refractory material which is prepared by using composite micro-powder and adding some additives.
Features of lable refractory castable
The main characteristics of ladle refractory castable are: good explosion-proof performance, high high temperature strength, strong slag erosion resistance.
Application of lable refractory castable
Steel furnace
blast furnace
Glass kiln
cement kiln
Ceramic tunnel kiln
