  • Castable refractory for cement kiln and boiler
  • Application:
    The Corundum wear castable: pulverized coal burner, fluidized bed, power generation boilers, rotary kiln mouth, cooler mouth.
    Alumina castables: cement kiln inlet, kilns, coolers, under the feeder.
    Clay castable: pre - heater with kiln hood and cyclone.
    Feature:
    According to the service conditions of different parts of cement kiln and boiler, corundum, high aluminum and clay castable prepared by corresponding refractory aggregate, binding agent, additive are selected. It is of high heat and cold strength, good wear-resisting property, resistance to heat shocks, anti-stripping and good stability of volume in high temperature.
