Special refractory brick series - corundum mullite brick
Corundum mullite brick is made with imported flake corundum and high-purity electric fused corundum as main raw materials, and the added superfine powder technology is applied. After mixing, drying, molding, and firing in a high-temperature shuttle kiln, is a reliable high-purity refractory powder. According to the product requirements, the proportion of organic composite filler is added, and it is formed by vacuumusion molding and high-temperature sintering. It is a lightweight mullite product. Corundum mullite bricks are widely used in equipment such slag oil gasification furnace, synthetic ammonia second-stage conversion furnace, carbon black reaction furnace, and refractory furnaces. 1. Low conductivity and low specific heat 2. High purity and low impurity content 3. High temperature resistance and can directly contact the flame 4. High strength and excellent shock resistance Application of corundum mullite brick It is suitable for the inner and back lining of various industrial furnaces in industries such asurgy, petrochemical, building materials, ceramics, and machinery. For example: cracking furnace, conversion furnace, heating device, refining device, regeneration, hot blast furnace, heating furnace, homogenizing furnace, heat treatment furnace, resistance furnace, tunnel kiln, roller kiln, shuttle kiln, bellshaped kiln, glass pool furnace, etc.
