Mullite Insulating Brick
Low iron content and low temperature smelt of alkali metal, good refractoriness and good affection of reducing atmosphere resistance.
The products has structure uniform, light weight, high cold crushing strength and good insulation resistance, so the furnace body has less heat storage during cooling and energy can be saved effectively.
At high temperature, the product has advantages with high strength, volume stability and good thermal shock resistance. After product being sintered, it will be grinded and shaped carefully to reach small size tolerance.
It is widely used for burning kiln, smelting furnace, refining furnace, heater in refractory, iron and steel, ceramics industries etc.
