Description:It is usually called magnesia-chrome brick, made of sintered magnesite clinker and chrome ore and sintered at high temperature about 1,600oC. Its mineral component is mainly periclase, magnesia-chrome spinel and a certain number of silicate phase. The product is a kind of basic refractory with the advantages of high temperature structural strength, excellent thermal shock resistance, high refractoriness and strong resistance to alkaline mass. Magnesia-chrome brick is extensively applied in non-ferrous furnaces, electric arc furnaces, open hearth furnaces, converters, torpedoes, vacuum refining furnaces, burning zones of cement rotary kilns, recuperators of glass kilns. Our branch produces a great amount of magnesia-chrome series bricks containing Cr2O3 8-20% or even more according to the requirements of customers. The quality reaches the advanced level in China, finding the favor in the customers. The high-chrome brick is made of synthesized materials, concentrated chromite and appropriate amount of additive. After the reaction of chromite with magnesia clinker in synthesized material, spinel phase forms, so the product features low apparent porosity, high crushing strength, good corrosion resistance and so on. It is widely used in non-ferrous furnaces.
