Main properties and uses of magnesia carbon bricks

Date:2018-05-03 Author: Click:

Magnesia carbon bricks are made of magnesia, heavy magnesia, fused magnesia, high purity magnesia, high quality graphite and bauxite additives. The performance of magnesia carbon brick has great relationship with the graphite content in bricks. With the increase of graphite content, the strength of brick decreases, the thermal expansion rate decreases, and the residual expansion rate increases.

The price of magnesia carbon brick

Therefore, the graphite content in the brick should be controlled about 20%. Magnesia carbon brick has little wettability to slag and has excellent spalling resistance and corrosion resistance. It is suitable for slag line location of ladle, especially for multi furnace continuous casting. In order to meet the needs of producing clean steel, the application area of magnesia carbon brick has expanded from the slag line to the side wall when refining in ladle.

When building magnesia carbon bricks on ladle, be careful not to mix with bricks with high Si02 content. Otherwise, the local melting loss of magnesia carbon bricks will be increased.

It is mainly used for lining, tapping hole, hot spot of high power electric furnace wall, as well as lining of refining furnace lining and slag line of high power electric furnace.
