Fused rebonded magnesia chrome bricks are re-sintered products made of fused magnesia chrome particles.
Magnesium-aluminum-chromium composite spinel brick is a new type of high-grade composite material, which developed by Rongsheng according to the characteristics of zinc volatilization kiln. It not only has excellent scouring and erosion resistance, but also has good peeling resistance. After being used by Zhuzhou Smelting Co., Ltd., Yunnan Copper Zinc Co., Ltd. and other large zinc smelting enterprises, this kind of brick has obvious advantages over chrome slag bricks, direct-bonded magnesia chrome bricks, magnesia bricks and thermal shock resistant high alumina bricks. It is the ideal material for zinc volatilization kilns.
