Hercynite Fused for Cement Kiln:
Compared with traditional brick spinel, magnesium oxide - aluminum ferrite spinel brick has excellent structure flexibility, low thermal expansion, low heat conductivity and good alkali salt erosion ability. Especially for large-scale rotary kiln (the maximum daily output 6 800t), the life of hercynite fused brick can be up to 17 to 18 months. After using, the brick Chemical and microstructural analysis results showed that even at extremely high volatile, large thermal mechanical stress and rotary kiln operating conditions, magnesia - hercynite brick erosion rate remains very low.

回复删除Ladle magnesia carbon brick takes use of fused magnesia sand, high carbon graphite as raw material, adding proper amount of antioxidants, bonded with phenolic resin,made by high pressure molding. Ladle mgo-c bricks has good erosion resistance and shock resistance. Ladle lining magnesia carbon brick are generally used in furnace lining.
