Product Introduction
Lightweight insulating castable is made from high-quality lightweight aggregates and powders, combined with binders. It has a bulk density ranging from 0.6 to 1.7 g/cm³ and is suitable for use at temperatures between 800°C and 1600°C. Compared to dense castables, lightweight castables have a lower thermal conductivity and significantly reduce the weight of the furnace lining. The rate of combustion temperature diffusion in industrial kilns can be reduced by approximately 30% compared to dense castables. Therefore, using lightweight insulating castables as an insulation layer effectively lowers the thermal energy consumption of industrial furnace linings.
Lightweight castables are typically applied as the first layer of the kiln lining, closely adhering to the furnace shell. However, high-grade lightweight castables, such as alumina hollow ball castables and lightweight mullite refractory castables, can also be used as working layers in some lightweight kilns. This allows them to be used directly, reducing the overall furnace weight while lowering heat loss and saving energy costs.
