Light weight insulating castable is made of high quality, high strength material aggregate, superfine powder and composite additive to be with high refractoriness, high strength and low thermal conductivity. It has the advantages of low density and low thermal conductivity, which not only reduce the thermal energy consumption of industrial furnace, but also reduce the weight of the lining.
Applications:
It is suitable for middle and low temperature furnace linings,ceiling and mobile cover.
Use:Rotary kiln and industrial kiln for heat insulation or single-layer lining.
