The calcined magnesium powder is made of natural magnesite ore and calcined in a high temperature shaft kiln. It is the raw material for making bricks and producing unshaped refractory materials, and the finished products are used for steelmaking, electric furnace bottom and ramming furnace lining.
Magnesite ore with more than 46% content is mainly used for re calcined magnesium powder. Magnesite ore is calcined in a high temperature shaft kiln and heated to 1400-1800 ℃ when Mg (CO3) is completely decomposed to generate periclase, which becomes hard reddish brown re calcined magnesium with high fire resistance. It is an ideal raw material for the production of unshaped refractory materials, and the products are used for steel making open hearth furnace, electric furnace bottom and ramming furnace lining.
The reburning magnesium powder plant said that sewage treatment plays a role in magnesium oxide. Magnesium oxide can react with sewage to generate magnesium hydroxide. Powdered magnesium oxide reacts with sewage to generate magnesium hydroxide first. Magnesium oxide reacts with sewage to generate magnesium hydroxide. At the same time, it reacts with sewage to remove harmful impurities in sewage. Magnesium hydroxide can be used as a neutralizer. Magnesium hydroxide is alkaline and has good adsorption performance. It can be used as acid containing waste gas Neutralizers for wastewater treatment, waste liquid treatment containing heavy metals and organic substances have been widely used in water treatment systems in recent years.
When magnesite is calcined at 1800 ℃, carbon dioxide completely escapes. Magnesia forms a compact block of periclase. Weigh the calcined magnesium (also known as sintered magnesium powder). This kind of calcined magnesium has a high refractoriness. Its main component is magnesium oxide, which is made of natural super grade magnesite ore through flotation purification, light burning, fine grinding, high-pressure ball pressing, and ultra-high temperature oil shaft kiln calcination.
