MgO-C砖被广泛用作BOF、RH、电炉等炼钢设备的内衬材料。但碳含量较高的MgO-C材料也有一些缺陷,例如,由于高的热导率,炉壳产生大的应力和高的热量损失。由于碳的氧化程度决定了MgO-C材料的损毁速率,因此与高碳MgO-C材料相比,低碳MgO-C材料可能更耐用。而低碳MgO-C材料的问题则 MgO-C bricks are widely used as lining materials for BOF, RH, electric furnace and other steelmaking equipment. However, the higher carbon content MgO-C material also has some drawbacks. For example, the furnace shell generates large stress and high heat loss due to the high thermal conductivity. Since the degree of carbon oxidation determines the rate of destruction of MgO-C materials, low carbon MgO-C materials may be more durable than high carbon MgO-C materials. The issue of low-carbon MgO-C materials then
