Raw materials for magnesia carbon bricks
High melting point basic oxide magnesium oxide (melting point 2800 ℃)
High melting point carbon materials that are difficult to be wetted by slag
Various non oxide additives
Features: No sintering, combined with carbon based binder
Magnesia Carbon Brick Characteristic
Magnesia Carbon Brick Characteristic
Good high-temperature resistance
Strong resistance to erosion
Good thermal shock resistance
Low creep under high temperature environment
Magnesia carbon brick, as a composite refractory material, effectively utilizes the slag corrosion resistance of magnesium oxide and the high thermal conductivity and low expansion of carbon, making up for the poor peeling resistance of magnesium oxide.
