Magnesia ferric spinel brick is a new generation of chromium-free alkaline refractory material for belt firing in large-scale rotary kiln. It uses high purity spinel as raw material and sintering at high temperature to form chromium-free environmental protection products.
Magnesia ferric spinel brick products have the characteristics of high compressive strength, good thermal shock stability, good thermal creep resistance, corrosion resistance and permeability, and high softening temperature under load, and also have the characteristics of easier to stick to the kiln skin than directly combined magnesia chrome brick, which can effectively solve the problem of environmental pollution caused by hexavalent chromium generated in the use of magnesia chrome brick for cement kiln.
