MgO is the main component of lightly burned magnesia used as catalyst in magnesia chemical industry. Magnesium oxide plays a special role in steelmaking because of its unique melting point. There are many kinds of specifications for light burned magnesia balls. It is mainly composed of 55% magnesia calcined magnesium balls, 60% light burned magnesia balls and 65% light burned magnesia 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 in the industry is also called low-silicon light-burned magnesium balls. The silica content of low silicon light burned magnesia ball is generally less than 3%. Different steel grades have different requirements for the content of light burned magnesia ball and the content of silicon dioxide.
Determination of sulfur and pyrite and sulfur and arsenic in steel. Used as a standard for white pigments. Light Magnesium Oxide is mainly used as raw material for preparing ceramic, enamel, refractory crucible and refractory bricks. It is also used as a polishing adhesive url] coating and paper filler, as an accelerator and activator for chloroprene and fluororubber. After mixing with magnesium chloride and other solutions, Magnesium Oxide can be made into water. It is used medicinally as an antacid and laxative, for gastric hyperacidity and for gastric and duodenal ulcers, as a catalyst in the chemical industry and as a raw material for the manufacture of magnesium salts. It is also used for making glazing, dyed dregs and phenolic plastics. The heavy Magnesium Oxide rice milling industry is used for grinding and semi rolling. The construction industry is used to make man-made chemical flooring marble heat shield board sound insulation board plastic industry as filler. It can also be used to produce other magnesium salts.
The natural super magnesite is selected for flotation purification and is calcined by light burning, fine grinding, ball pressing and ultra-high temperature oil shaft kiln. It is a high quality raw material for making bricks and indefinite refractories. Light burned magnesium oxide with 97% MgO content was produced by ball pressing and high temperature shaft kiln calcination. The product has good sintering degree and dense crystallization. It is a high-quality raw material for producing medium-grade magnesia refractory products. It can also be used to manufacture various magnesia bricks, magnesia-alumina bricks, ramming materials, furnace filling materials and so on. It contains more impurities and is used for laying the bottom of steelmaking furnace. Refired magnesia
