JM23 Mullite Insulation Brick

JM23 Mullite Insulation Brick Introduce
 
JM23 Insulation Brick, using high pure mullite as raw material, is made by adding alumina powder according to different type and then sintering in high temperature. JM insulating brick is the new energy saving material for insulation. JM23 insulation brick are produced accordance with German industrial standard that especially for export to foreign countries.
 
Application of JM23 Mullite Insulation Brick
 
JM23 Insulation Brick are widely used for heat-insulating purpose in many kinds of industrial furnace, electric furnace and metallurgical stove,Cracking furnace in petroleum, Hot blast furnace in metallurgy,Ceramic roller kiln, tunnel kiln, shuttle kiln for electrical porcelain,Pot furnace for glass industry, Inner lining of kinds of electrial furnaces and high temperature equipment.
