Product Description

Special Insulating Refractory Brick Mullite Insulation Brick
The Description:
Mullite thermal insulation refractory brick refers to mullite as the main raw material, through grinding, mixing, forming, drying, sintering and other processes made with excellent thermal insulation, refractory properties of the brick. Mullite is a natural mineral with a magnesia-aluminosilicate structure, and its main chemical components are SiO2, Al2O3 and MgO

Product feature:
Special Insulating Refractory Brick Mullite Insulation Brick Low iron content and low temperature smelt of alkali metal,Good refractoriness and good affection of reducing atmosphere resistance.The product is featured with even structure,light weight,high CCS 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 is characterized by high strength,stable volume and good thermal shock resistance.After product being sintered,it will be ground resulting in small size tolerance and can meet the requirements of construction.
