What are the main components of heavy burned magnesia and light burned magnesia!

The main component of heavy burned magnesia is MgO. Magnesium oxide plays a special role in steelmaking because of its melting point. Heavy burned magnesia and light burned magnesia balls have many specifications and contents. It mainly includes 55% light burned magnesium balls, 60% light burned magnesium balls and 65% light burned magnesium balls. Light burned magnesium balls have certain requirements for other small indicators and moisture. According to the content of silicon dioxide in light burned magnesium balls, it is also called low silicon light burned magnesium balls in the industry. The silica content of low silicon light burned magnesium spheres is generally less than 3%. Different steel grades have different requirements for the content of light burned magnesium ball and silicon dioxide.

It is used to determine sulfur and pyrite in coal and sulfur and arsenic in steel. Used as a standard for white pigments. Light magnesium oxide is mainly used as raw material for preparing ceramics, enamel, refractory crucible and refractory brick. It is also used as polishing agent, adhesive url] coating] and paper filler, accelerator and activator of neoprene and fluororubber.

Calcined magnesia

After mixing with magnesium chloride and other solutions, magnesium oxide water conditioner can be made. In medicine, it is used as antacid and laxative, for hyperacid stomach and two finger intestinal ulcer. It is used as catalyst and raw material for manufacturing magnesium salt in chemical industry. It is also used in the manufacture of glass, dyed meal, phenolic plastics, etc. Heavy magnesium oxide is used for firing, grinding and half drum in rice milling industry. The building industry is used to make artificial chemical floor, artificial marble heat proof board, sound insulation board, and plastic industry is used as filler. It can also be used to produce other magnesium salts.

It is made of natural magnesite ore by flotation purification, light burning, fine grinding, ball pressing and shaft kiln calcination. It is the raw material for making bricks and refractory materials. It is produced from light burned magnesium oxide with 97% MgO content by ball pressing and high temperature shaft kiln calcination. The product has good sintering degree and dense crystallization. It is the raw material for the production of medium-grade magnesium refractory products. It can also be used to manufacture all kinds of magnesium bricks, magnesium aluminum bricks, ramming materials, furnace charging materials, etc. Those containing more impurities are used to pave the bottom of steelmaking furnace, etc.
