Product description

High alumina castable refractory formulated with soft clay as the binding agent, alumina clinker, clay clinker or corundum, mullite, etc. as refractory aggregates and powders and additives. According to the types of refractory aggregates and powders used, clay-bonded refractory castables are divided into clay-based, high-aluminum, corundum-mullite, lightweight high-aluminum, etc. It has excellent properties such as good thermal expansion resistance and strong peeling resistance. Mainly used in thermal equipment such as high furnaces, soaking furnaces, and heating furnaces.

Application of high alumina castable refractory

High alumina castable refractory are used in various heating furnaces, soaking furnaces, circulating fluidized bed boilers, waste incinerators, waste heat power generation boilers, hot blast furnaces, continuous casting tundish, hot metal tanks and tapping troughs, etc.
