Description of Refractory Mullite Insulating Brick :
Mullite bricks are high alumina refractories with mullite as the main crystal phase. Generally, the alumina content is between 65% and 75%, and the refractory of mullite brick is relatively high, reaching above 1790 ℃. The starting temperature of load softening is 1600 ~ 1700 ℃. Good thermal shock resistance. There are two kinds of sintered mullite bricks and fused mullite bricks.
Applications of Refractory Mullite Insulating Brick :
Mainly used for hot blast furnace top, blast furnace stack and bottom, glass furnace regenerator, ceramic sintering kiln, dead corner lining of petroleum cracking system,ethylene pyrolysis furnaces, tubular furnaces,reforming furnaces of synthetic ammonia,gas generators,linings or heat-insulating materials of the industries,etc.
