Magnesia Chrome Bricks are made from high grade magnesite clinker and chrome oxide. By high pressure shaping and high temperature firing, its characteristic is the high direct-bonding rate, and big crystallite. It has a good thermal spalling resistance. The low-basic neutral nature gives itself a good slag resistance when servicing low-acid feed furnaces. The bricks is a realistic lining material for refining furnace, electric furnace, glass melting furnace and cement rotary kiln etc.
