Magnesia Carbon Brick--Refractory Brick---Changxing Refractory material

Magnesia Carbon Brick is widely used in Electric Arc Furnace sidewalls, converters, hotspots and coldspots, and ladle furnace slag lines.

Magnesia Carbon Brick is mainly used for electric furnace lining, which enjoys advantages including high temperature resistance strength, corrosion and spalling resistance. 

Magnesia Carbon Brick

Introduction:
Magnesia carbon brick series used for the electric furnace are made by adoption of fused magnetite, high-purity magnesium sand and graphite as principal raw material, through high-pressure molding and low-temperature treatment. This product is mainly used for electric furnace lining, which enjoys advantages including high temperature resistance strength, corrosion and spalling resistance. According to the smelting conditions and the kind of smelting steel, different brands magnesia carbon bricks are available. Magnesia-carbon bricks are resin bonded bricks containing high-purity fused and or sintered magnesia and flake graphite as their main ingredients.

Advantages:
It has excellent corrosion resistance together with good thermal shock properties. It offers good oxidation resistance due to use of high purity flake graphite.

Application:
It is widely used in Electric Arc Furnace sidewalls, converters, hotspots and coldspots, and ladle furnace slag lines.

Technical Innovation of Carbon Brick for Blast Furnace Hearths

Carbon Brick for Blast Furnace Hearths

Possessing with the excellent corrosion resistance and high thermal conductivity which can lead to easily form a protective layer for blast furnace hearth, refractory brick carbon bricks have been used as refractory material for hearths for more than half century.

To further improve its performance, the refractory experts have carried out many investigations recently. Finally, they find out some main reasons which caused the damage. They are including as below:
1) The penetration of molten iron into pores.
2) Erosion due to direct contact with molten iron (dis-solution by carburizing).
3) Embrittlement of the material on hot side (loss of cooling capacity).

In order to enhance its corrosion resistance, the experts have developed new technology to get new magnesia carbon brick through numerous experiments.
1) Add the aluminum oxide which has a good resistance to molten steel.
2) Reduce the pore diameter to prevent the penetration of molten steel and other impurity items.
3) Enhance the high thermal conductivity to reduce the surface temperature.
4) Add the TiC to improve the corrosion against molten steel, increase its viscosity and slow down the flow which could effectively reduce the damage on the MgO-C bricks.
