The role of magnesia carbon brick

Magnesia-carbon bricks are made of high melting point alkaline oxide magnesia (melting point 2800C) and high melting point carbon materials that are difficult to be infiltrated by slag as raw materials, and various non-oxide additives are added. Non-burning carbon composite refractory material combined with carbon binder. Magnesia-carbon bricks are mainly used for the lining of converters, AC electric arc furnaces, DC electric arc furnaces, and the slag line of ladle.

 

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 for the biggest disadvantage of poor spalling resistance of magnesia.

 

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