On the stage of the metallurgical industry, magnesite plays a pivotal role and is undoubtedly a mainstay. With its excellent high-temperature resistance, it has become the ideal choice for producing refractory materials. After special processing, magnesite can be transformed into metallurgical magnesia, magnesia bricks, magnesia-chrome bricks, magnesia-alumina bricks, and silica-magnesia bricks, etc., with a refractoriness of over 2000℃. These refractory materials are widely used in the linings of high-temperature kilns such as open-hearth furnaces, electric furnaces, converters for steelmaking, and non-ferrous metal smelting furnaces. During the steel smelting process, the temperature inside the furnace is extremely high, accompanied by the erosion of various chemical substances. However, the furnace linings made of magnesite can withstand such harsh environments, effectively resisting high temperatures and chemical erosion, ensuring the smooth progress of metallurgical production, significantly improving the service life and production efficiency of the furnaces, and reducing production costs. For example, in the steelmaking workshops of large iron and steel enterprises, the application of magnesite refractory materials has extended the maintenance cycle of steelmaking furnaces, greatly improved production efficiency, and created considerable economic benefits for the enterprises.
