Low cement refractory castable is a common castable of different materials in refractory castable, and it is also one of the hot castable for refractory castable. So what is the use of low cement castable?

Low cement refractory castable refers to the cement content is relatively low castable, cement content is generally 5%-7%, cement content below 1% is called ultra-low cement castable. Our company produces ultra-low cement corundum mullite castable, mainly using corundum (or high bauxite), α-Al2O3 powder, cement and other raw materials, plus a certain proportion of the binder mixing. Suitable for cement kiln front and back, kiln door cover, cooling machine and other industrial kiln lining.

Main types of low cement castables:

Low cement (Cao content 1%~2.5%)

Ultra-low cement (CaO 0.2-1%)

No cement (CaO≤0.2%)

The low here refers to the content of cement, low cement castable, ultra-low cement castable temperature than the same material of ordinary refractory castable temperature is higher, low cement castable for a variety of high temperature burner lining, heating furnace water cooling pipe dressing lining.
