In today’s industrial field, magnesia chrome bricks play a vital role with their excellent properties.
Magnesia chrome brick has been widely used in iron and steel metallurgy industry. In steel converter, the temperature inside the furnace is extremely high, and accompanied by violent chemical reaction and mechanical erosion. Magnesia chrome brick is an ideal material for Bessemer lining because of its good high temperature resistance, slag erosion resistance and mechanical strength. It can withstand the high temperature impact of molten steel and the chemical erosion of slag to ensure the stable operation and long service life of the converter. In electric furnace steelmaking, magnesia chrome bricks also perform well. The temperature in the electric furnace can be as high as thousands of degrees, and the requirements for furnace lining materials are extremely demanding. Magnesia chrome brick can not only withstand high temperature, but also resist local overheating and strong thermal shock effect caused by arc action. Its stable chemical properties make it less prone to chemical reactions when in contact with various complex liquid steel components, thus ensuring the quality of liquid steel.
In the cement production industry, cement rotary kiln is the core equipment. The working environment in rotary kiln is extremely harsh, high temperature, high wear, chemical erosion and other factors coexist. Magnesia chrome brick is widely used in cement rotary kiln lining because of its excellent high temperature resistance and chemical erosion resistance. It can withstand the high temperatures generated during the calcination of cement clinker, while resisting the chemical attack in the cement raw materials and combustion products. The use of magnesia chrome brick can effectively extend the operation period of cement rotary kiln and improve the production efficiency.
In the non-ferrous metallurgy industry, magnesia chrome brick also has an irreplaceable position. For example, in the smelting process of non-ferrous metals such as copper and nickel, the temperature and chemical environment in the smelting furnace are complex and changeable. Magnesia chrome brick can maintain stable physical and chemical properties at high temperatures and resist the erosion of metal melt and slag. It provides a reliable lining guarantee for the non-ferrous metallurgy process and ensures the smooth progress of the smelting process.
In the refractory industry, magnesia chrome bricks occupy an important position. Because of its excellent fire resistance, it is widely used in the key parts of various high temperature kilns. In glass melting kiln, magnesia chrome brick can withstand high temperature erosion and mechanical erosion of glass liquid to ensure the stable operation of glass melting kiln and the quality of glass products. In ceramic industrial kilns, magnesia chrome bricks can resist various adverse factors in the high-temperature sintering process, providing guarantee for the high-quality production of ceramic products. In some special industrial furnaces, such as calcium carbide furnaces, yellow phosphorus furnaces, etc., the high temperature resistance and corrosion resistance of magnesia chrome bricks have been fully utilized to ensure the smooth progress of these special processes.
In addition, in other high-temperature industrial fields, magnesia chrome bricks also play an important role. It provides a solid material guarantee for the development of modern industry, and plays an important role in the process of promoting industrial progress.
