Magnesia carbon brick is a high melting point basic oxide magnesium oxide (melting point 2800 ° C) and a high melting point carbon material which is difficult to be infiltrated by slag as a raw material, and various non-oxide additives are added. A non-burned carbon composite refractory material combined with a carbonaceous binder. As a composite refractory material, magnesia carbon brick effectively utilizes the strong slag corrosion resistance of magnesia and the high thermal conductivity and low expansion of carbon, which compensates for the biggest disadvantage of poor flaking resistance of magnesia.
Its main features are:
1. It has good high temperature resistance
2. Strong slag resistance
3. Good thermal shock resistance
4. Low temperature creep

Magnesia carbon brick is mainly used for: lining of converter (MC12---MC18), AC arc furnace, DC arc furnace, low-cladding for ladle (MC-8A, MC-10A), slag line for ladle ( MC-12A, 14A, 16A, 18A) and other parts.
