Magnesium-carbon bricks
Magnesium-carbon bricks is a kind of high melting point basic oxide magnesium oxide (2800 ℃) and high melting point carbon material which is difficult to be infiltrated by slag as raw materials, adding various non oxide additives. The unburned carbon composite refractories are made of carbon binder. Magnesia carbon brick is mainly used for lining of converter, alternating current arc furnace, direct current arc furnace, slag line of ladle, etc.
As a kind of composite refractories, magnesia carbon brick effectively utilizes magnesia's strong slag corrosion resistance, high thermal conductivity and low expansion of carbon, and compensates for the biggest disadvantage of magnesia's poor spalling resistance.
Its main characteristics are: good high temperature resistance, strong slag resistance, good thermal shock resistance, low high temperature creep.
