Product description
The high strength castable refractory lining is prepared by adding special grade aluminum bauxite clinker or corundum as aggregate and powder, adding binder, admixture and heat-resistant stainless steel fiber. It has the characteristics of high compressive strength, high flexural strength, thermal shock resistance, wear resistance and volume stability. Such high strength castable refractory is suitable for furnace wall, furnace roof, furnace of cemented bed boiler, kiln mouth, cooling machine and feed tank of cement kiln. And other parts.
Applications of castable refractory lining:
Refractory castables 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.
