Refractory Magnesia Carbon Brick

Product introduction of Magnesia carbon bricks

Magnesia carbon brick is made of high purity magnesium powder, carbon material (including graphite) and tar pitch or resin by batching, hot mixing and forming, roasting at about 300℃ or above 1000℃.

Advantages of Magnesia carbon bricks

Magnesia carbon brick is composed of magnesium oxide and carbon, both of which have high melting point, and the two components do not solid melt, so MG-carbon brick has high melting resistance.

Due to the excellent heat shock resistance of dry graphite, magnesia carbon brick inheriting the excellent characteristics of graphite has the characteristics of high thermal conductivity, small linear expansion coefficient and elastic modulus, and high temperature strength, basically avoiding the tissue damage and spalling caused by cracking in the process of use.

Application of Magnesia carbon bricks

Magnesia carbon brick is mainly used in clearance and slag line when it is used in ladle furnace and ladle refining. According to the operating conditions, these parts require the use of refractory materials must have high temperature resistance, heat shock resistance, resistance to slag erosion caused by mechanical erosion.
