(Summary description)Refractory material is a solid material that can resist the effects of high temperature and is widely used in the metallurgical industry. Henan Weilong Special Refractories is an enterprise specializing in the research and development of special refractories for steelmaking furnaces. Its refractory spray coatings, refractory castables, environmental protection gun clay and other products have experienced 20 years of market test and have won unanimous praise from more than 300 steel plants, power plants, and cement plants. Refractory materials are usually divided into: acidic refractories (quartz, silica bricks); semi-acid refractories (semi-silica bricks); neutral refractories (chrome bricks, clay bricks, high Aluminum bricks); basic refractory materials (magnesia bricks, chrome magnesia bricks, magnesia alumina bricks, dolomite bricks, magnesia, dolomite and magnesia refractory clay), etc. Alkaline refractories are currently widely used in smelting equipment due to their excellent characteristics such as high refractoriness, good thermal stability, and good slag resistance. In the converter and electric furnace steelmaking process, molten steel will mechanically scour the refractory lining of the furnace. At the same time, the constituent elements of the refractory industrial electric furnace are dissolved into the molten steel and chemically reacted with the molten steel. The mechanical scouring of molten steel on the furnace lining and the chemical reaction between the two: on the one hand, cause damage and erosion of the refractory materials of the furnace lining; on the other hand, it will affect the quality of molten steel and steel.
