The magnesia-carbon brick magnesia-carbon refractory was successfully developed by the United States in the mid-1960s. In the 1970s, the Japanese steel industry began to use magnesia-carbon bricks in water-cooled electric arc furnace steelmaking. At present, magnesia-carbon bricks have been widely used in steelmaking around the world, and have become a traditional use of graphite. In the early 1980s, magnesia-carbon bricks began to be used for the lining of oxygen top-blown converters.
At present, most of the materials used for oxygen top-blowing steel lining in the UK are magnesia-carbon bricks, and the lining life is 1,000 times to 1,500 times, while in Japan, the life of the furnace lining is 2,000 times to 2,500 times.
Magnesia-carbon bricks are steel-making consumables. High temperature resistance of about 1700 degrees. In great demand. The main raw materials are magnesia and graphite, and the binder is phenolic resin.
Magnesium-carbon refractory is a carbon composite refractory widely used in industrial production. It has good performance in practical application, especially slag resistance.
