The raw material of the preparation of magnesia carbon bricks is 98% MgO fused magnesia, magnesia carbon bricks are they have low porosity, resistance to slag erosion, thermal shock resistance and high temperature strength characteristics, magnesia chromium bricks, they are mainly used in basic oxygen furnace, ladle slag line and electric arc furnace hot spots. Magnesia carbon brick is a kind of high quality refractory material. Their main components are magnesium oxide and carbon, with a magnesium oxide content of 60-90% and a carbon content of 10-40%. This material is made from high purity magnesium oxide particles, carbon material, tar, asphalt or resin baked at high temperatures. These magnesia refractory bricks have the characteristics of slag corrosion resistance, heat shock resistance, thermal conductivity and so on.

Magnesia carbon brick is an unburned carbon composite refractory material, which is made of magnesium oxide with a high melting point (2800℃) of basic oxide and a high melting point of carbon material, which is difficult to be corroded by slag, and has added various non-oxide additives and carbon adhesives.

As a kind of composite refractory material, magnesia-carbon brick effectively uses the strong slag corrosion of magnesium, effectively improves the thermal conductivity and low expansion of carbon, and makes up for the shortcomings of magnesium's poor spalling resistance. Magnesia carbon brick is mainly used in the lining of converter, electric arc furnace, DC electric arc furnace, ladle slag line and other parts.
