Magnesia carbon bricks are made of high melting point alkaline oxide magnesium oxide (melting point 2800℃) and high melting point carbon materials that are difficult to be wetted by slag as raw materials, and various non-oxide additives are added. It is a non-burning carbon composite refractory material combined with a carbon binder. Magnesia carbon bricks are mainly used for the lining of converters, AC arc furnaces, DC arc furnaces, slag lines of ladles and other parts. As a composite refractory material, magnesia carbon bricks effectively utilize the strong slag erosion resistance of magnesia sand and the high thermal conductivity and low expansion of carbon, compensating for the biggest disadvantage of poor spalling resistance of magnesia sand.

      The main features are: good high temperature resistance, strong slag resistance, good thermal shock resistance, and low high temperature creep.
