Rosewool Magnesia Carbon Bricks To Nigeria

This Nigerian customer needs magnesia carbon bricks for his furnace. Magnesia carbon bricks are made of high melting point basic oxide magnesia (melting point 2800 ℃) and high melting point carbon materials that are difficult to be infiltrated by slag. Non-oxide additives. A non-burning carbon composite refractory material combined with a carbonaceous binder.



Magnesia-carbon bricks are made of magnesia, dead-burned magnesia, fused magnesia, high-purity magnesia, high-quality graphite and bauxite additives. The performance of magnesia carbon bricks has a lot to do with the graphite content in the bricks. As the graphite content increases, the strength of the brick decreases, the thermal expansion rate decreases, and the residual expansion rate increases.

When building magnesia-carbon bricks on ladles, care should be taken not to mix them with bricks with high Si02 content. Otherwise, the local melting loss of magnesia carbon bricks will be increased, and the melting loss mechanism is as follows;

It is mainly used for the furnace lining and tapping hole of the steelmaking oxidation conversion furnace, the hot spots of the furnace wall of the high-power electric furnace, the lining of the refining furnace outside the furnace, and the slag line of the steel ladle, etc.
