Strong Slag Resistance Magnesia Carbon Brick

Product introduction of Magnesia carbon bricks

Magnesia carbon bricks are made of high melting point alkaline oxide magnesium oxide (melting point 2800℃) and high melting point carbon material which is difficult to be infiltrated by slag as raw material, adding various non-oxide additives. Combined with carbon bonding agent to make a non-burning carbon composite refractory material.

Advantages of Magnesia carbon bricks

Strong slag resistance

Good resistance to thermal shock

Low high temperature creep

Good high temperature resistance

Application of Magnesia carbon bricks

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, compensating for the biggest drawback of poor flaking resistance of magnesia. Magnesia carbon bricks are mainly used in the lining of converter, AC electric arc furnace, DC electric arc furnace, slag line of steel ladle and other parts.
