Magnesia Carbon Brick

MgO-C bricks are used extensively in high quality steel alloy making processes especially in basic oxygen furnaces, electric arc furnaces, ladle refining furnances. As a composite refractory, magnesia carbon brick effectively makes use of the strong slag erosion resistance of magnesia and the high thermal conductivity and low expansion of carbon, and compensates for the poor spalling resistance of magnesia. It has the characteristics of slag erosion resistance, slag permeability, thermal shock stability and thermal conductivity.

The main raw materials used in the production of MgO-C bricks are magnesia aggregate, graphite, resins, and other additives. Magnesia-carbon (MgO-C) refractory is important and widely used refractory in the steelmaking. It is characterized by a reduced slag infiltration depth and a high thermal shock resistance due to its carbon (C) content. Applications of this refractory not only include wear linings in basic oxygen furnace (BOF), electric arc furnace (EAF), and steel ladle, but also functional products such as purging and taphole bricks. The success of the use of basic MgO-C refractory in the steelmaking is based on its good properties of resistance to erosion, corrosion, and thermal shock.

Magnesia Carbon brick Advantages:

1.Good high temperature resistance
2.Strong anti-slag penetration resistance
3.Resistance to thermal shock
4.High Corrosion resistance to slag
5.Non-Wettability to molten slag
6.Increases lifespan of the vessal.
7.Low thermal expansion

MgO-C brick is a composite material based on MgO.These bricks show excellent resistance to thermal shock and corrosion at eleveted temperatures.MgO-C bricks are used extensively in Steel industry. Magnesia carbon bricks are mainly used for the lining and tapping port of steelmaking oxidation converter, the hot spot of high-power electric furnace wall, refining furnace lining, the slag line of steel barrel, etc.

Magnesia Carbon Brick Features:
