Magnesia-carbon bricks are very suitable for the requirements of iron and steel smelting due to their excellent high temperature resistance, slag corrosion resistance and good thermal shock stability. Taking advantage of the properties of carbon materials that are difficult to be wetted by slag and molten steel, high refractory properties of magnesia, high slag resistance and solubility resistance, and small creep at high temperature, magnesia-carbon bricks are used in slag lines and outflows with severe corrosion damage. Steel mouth and other parts. So far, huge economic benefits have been created due to the extensive use of magnesia-carbon bricks in the steelmaking process and the improvement of the iron and steel smelting process.
