Application range of magnesia carbon bricks
Application range of magnesia carbon bricks Application range of magnesia carbon bricks Magnesia carbon bricks are made of magnesia, dead-burned magnesia, fused magnesia, high-purity magnesia, high-quality graphite and bauxite additives. The performance of alumina magnesia carbon bricks has a great relationship 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. Refractory MgO-C bricks are very suitable for the requirements of steel smeltin. This kind of brick has the characteristics of high fire resistance, high corrosion resistance, excellent heat resistance, high temperature spalling stability, high thermal shock resistance, etc. It has been rapidly popularized and applied. Using carbon materials that are difficult to be wetted by slag, molten steel, and the high refractory properties of magnesia, high slag resistance and solubility, and lo
