Magnesium-Iron-Aluminum Composite Spinel Brick

The main raw materials of mgo-fe-spinel brick are high-purity magnesia and alumina-fe-spinel sand. Through reasonable proportion and high-pressure molding, the firing temperature and firing time are strictly controlled, so that the product has good flexibility and thermal shock stability, and there is no hexavalent chromium pollution to the cement. Furnace combustion area. The product has the advantages of high volume stability, high load softening temperature, good thermal shock resistance, better adhesion to kiln coating and erosion resistance than high-quality magnesia chrome bricks, small reaction to cement clinker, and far less impact on kiln skin falling off than magnesia chrome bricks. It has been proved that they not only have long life, smooth surface, but also have no harm of chromium.
