The main component of dead-burned magnesia light-burned magnesia is MgO, and the melting point of magnesia creates the special role of light-burned magnesium balls in steelmaking. Mid-grade magnesia and light-burned magnesia balls have a variety of specifications and contents. Mainly 55% magnesium content light-burning magnesium balls, 60% light-burning magnesium balls, and 65% light-burning magnesium balls. Light-burned magnesium balls have certain requirements for other small indicators and moisture. According to the content of silica in light-burned magnesium balls, there is also a saying in the industry that it is called low-silicon light-burned magnesium balls. The content of low-silicon light-burned magnesium balls is generally below 3%. Different steel grades have different requirements for the content of light-burned magnesium balls and silica.
Determination of sulfur in coal and pyrite and sulfur and arsenic in steel. Used as a standard for white pigments. Light magnesia is mainly used as a raw material for the preparation of ceramics, enamels, refractory crucibles and refractory bricks. Also used as polisher binder url] paint] and filler for paper, accelerator and activator for neoprene and fluororubber.
After mixing with solutions such as magnesium chloride, it can be made into magnesium oxide water. In medicine, it is used as an antacid and a laxative for gastric hyperacidity and duodenal ulcer disease. In the chemical industry, it is used as a catalyst and a raw material for the manufacture of magnesium salts. It is also used in the manufacture of glass, dyed meal, phenolic plastics, etc. Heavy magnesia is used in the rice milling industry for firing mills and semi-drums. The construction industry is used to make artificial chemical floors, artificial marble, heat protection panels, sound insulation panels, and plastic industry as fillers. It can also be used to produce other magnesium salts.
It is made by flotation and purification of natural magnesite ore through light burning, fine grinding, ball pressing and calcination in shaft kiln. It is a raw material for brick making and indefinite refractories. It is produced from light-burned magnesia with a MgO content of 97% by means of briquetting and high-temperature shaft kiln calcination. The product has good sintering degree and dense crystallization. It is the raw material for the production of mid-grade magnesia refractory products. Those containing more impurities are used for laying steelmaking furnace bottoms, etc.
