DETAILS

Aluminum magnesia carbon brick
The aluminum-magnesium carbon brick is a lining fire product which is made of super high alumina bauxite or corundum sand, magnesia sand and flaky graphite. It is characterized in that it has the advantages of high corrosion resistance and low peeling property due to carbon content at high temperature, and also has the advantage of exhibiting a high residual linear expansion ratio due to heat generation of spinel during use, and thus becomes a new development quality. Lined with bricks. . Containing Al2O3: 60%~69%, MgO: 7%~14%, C: 5%~12%. It has good resistance to slag erosion and thermal shock resistance, and has a slight amount of reburning expansion.

The aluminum-magnesium carbon brick has the advantages of anti-erosion, anti-flaking, balanced erosion, safe use, less slag adhering to steel, and easy unpacking. It is mainly used for the lining of Shenggang which is used in harsh conditions. In the continuous casting large tundish and the refining package, the molten pool part and the bottom of the package are lined with aluminum-magnesium carbon bricks. Mainly used in large converters and ultra-high power electric furnaces, ladle lining and furnace refining furnace lining.
