The aluminum-magnesia carbon brick 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, thereby becoming Newly developed high quality lining bricks. Containing Al2O3 60% ~ 69%, MgO 7% ~ 14%, C 5% ~ 12%. It has good slag corrosion resistance and thermal shock resistance, and has a slight amount of reburning expansion.

It has the advantages of anti-erosion, anti-flaking, balanced erosion, safe use, less slag dipped in steel, and easy unpacking. It is mainly used for the lining of Shenggang which is used in harsh conditions. In the continuous casting large trough and the refining package, the molten pool part and the bottom of the package are lined with aluminum-magnesium carbon bricks.

In order to improve its oxidation resistance, additives such as Si powder, Al powder, SiC powder or ferrosilicon powder may be appropriately added to the ingredients, and the resin is used as a binder, and is formed by high pressure molding, and can be used after being treated at 200 to 300 ° C, without using Calcination. Mainly used in large converters and ultra-high power electric furnace ladle lining and furnace refining furnace lining
