As a kind of refractory material, the magnesia chrome refractory brick is made of magnesite and chromium concentrate as the main raw material, molded through high pressure and fired in the high temperature.
Heat-resistance temperature, the maximum allowed environment temperature is 1700℃. It has features of high strength, high refractoriness under load, high alkali erosion resistance and high thermal shock resistance under the load conditions of 1500~1650℃. It has big advantages of environmental protection and long service life.
Direct Bonded magnesia chrome refractory brick is manufactured with quality magnesia and chromic oxide as the raw material, molded through high press and fired in the high temperature. It has features of large crystal and high direct bonding rate. The product also has good cracking resistance and good acid slag erosion resistance with its low-alkaline property. Finaly, the refractory brick is the ideal lining brick material for finery out of furnace, electric furnace, glass furnace, melting furnace and rotary cement kiln.
