IM 23 Mullite Insulation Brick for Steel Mill and Hot Blast Furnace
1. Lower content of iron, alkaline and impurities, good high temperature properties.
2. Homogeneous structure, light weight, energy saving because lower heat storage in the furnace during cooling cycles.
3. High strength, good thermal shock resistance under high temperature.
4. Precise sizes due to grinding and shaping after firing, which meets the requirement of construction.
Mullite brick can be in direct contact with the flame,this insulating brick can be used as linings or as thermal preservation layers in various industrial furnaces and kilns in metallurgical industry, ceramic industry, chemical industry, machinery industry, such as blast furnace, hot blast stoves ,electric arc furnace, cement kiln,melting furnace, ignition furnace, flue, refining equipment, heating equipment and piping, regeneration device, gas furnace, soaking furnace, annealing furnace, heat reaction chamber and other thermal industrial equipment.
