Lightweight insulating castable is a type of refractory materials characterized by low density and low thermal conductivity, offering excellent thermal insulation and moderate mechanical strength. They are widely applied in insulation layers across industries including steel, glass, ceramics, and cement. ·Low density: Reduces structural load and simplifies installation. ·Low thermal conductivity: Minimizes heat transfer and energy loss. ·Moderate strength: Capable of withstanding operational loads.
Power industry: boiler lining insulation layer.
Steel industry:Thermal insulation layers in blast furnaces and hot blast stoves.
Glass industry:Insulation zones in glass melting furnaces.
Ceramic industry:Thermal linings for ceramic kilns.
Cement industry:Insulation layers in cement rotary kilns.
