Low density: The density of lightweight mullite castables is usually between 0.5-1.5g/cm³, which is lighter than traditional refractories. This allows it to form a lighter load inside the heating furnace, reducing the pressure on the heating furnace structure.
Low thermal conductivity: The thermal conductivity of lightweight mullite castable is very low, which can effectively reduce heat conduction. This helps to improve the thermal efficiency of the heating furnace and reduce energy consumption.
Excellent high temperature resistance: Light mullite castable can withstand high temperature environment, its fire temperature can reach 1600ºC or more. This gives it excellent performance and long life in high temperature heating furnaces.
Low coefficient of thermal expansion: Light mullite castable has a low coefficient of thermal expansion and excellent thermal stability. It can reduce the influence of thermal stress under high temperature conditions and delay the aging and fracture of materials.
Good insulation performance: Light mullite castable has good insulation performance, which can effectively prevent heat loss, reduce the temperature of the furnace wall, and improve the safety of the working environment.
Our total annual production capacity is about 100,000 tons of dense-shaped refractory product, and 100,000 tons of monolithic refractory product.
We have three tunnel kilns for silicon-aluminum dense bricks and one new plant for the monolithic refractory.
We're sure our custom-made products and professional services will bring you a stable quality supply and more profit.
