Magnesia carbon brick

Magnesia carbon brick is based on high melting point basic oxide magnesium oxide (melting point 2800 ° C) and high melting point carbon material which is hard to be infiltrated by slag as raw materials, and various non-oxide additives are added. Non-burning carbon composite refractory material combined with a carbonaceous binder. Magnesia-carbon brick is mainly used in converter, AC electric arc furnace, DC electric arc furnace lining, ladle slag line and other parts.
As a composite refractory material, magnesia-carbon brick effectively utilizes the strong slag erosion resistance of magnesia and the high thermal conductivity and low expansion of carbon, which compensates the biggest disadvantage of poor resistance to flaking of magnesia.
Its main features are: good high temperature resistance, strong slag resistance, good thermal shock resistance, low temperature creep.
