Dead Burnt Magnesite powder
Why the Burnt Magnesium Powder is strong?
The reburned magnesium powder is made by using natural magnesite ore and calcined by a high temperature shaft kiln. It is a raw material for brick making and production of amorphous refractories. The finished products are used in steel making, electric furnace bottoms and linings
The calcined magnesium powder is mainly selected from magnesite ore with a content of more than 46%. When the magnesite ore is heated to 1400-1800 °C by high temperature shaft kiln, Mg(CO3) is completely decomposed to form periclase, which becomes a hard reddish brown burnt. Magnesium, which has a high degree of refractoriness. It is an ideal raw material for the manufacture of amorphous refractories. The products are used in steelmaking open hearth furnaces, electric furnace bottoms and linings.
The function of sewage treatment in magnesium oxide is that the magnesium oxide powder reacts with the sewage to form magnesium hydroxide. The powdered magnesium oxide reacts with the sewage to form magnesium hydroxide first, and the magnesium oxide reacts with the sewage. At the same time of magnesium hydroxide, the harmful impurities in the sewage are reacted and treated. The use of magnesium hydroxide can be used as a neutralizing agent, the magnesium hydroxide is alkaline, the adsorption performance is good, and it can be used as an acid-containing waste gas, wastewater treatment, Neutralizing agents containing heavy metals and organic waste liquids have been widely used in water treatment systems in recent years.
When magnesite is calcined at 1800 °C, carbon dioxide completely escapes, magnesium oxide forms a dense block of periclase, and weighed magnesium (also known as sintered magnesium powder), which has a high degree of refractoriness. Its main component is magnesia, which is selected from natural super magnesite ore by flotation purification, light burning, fine grinding, high pressure ball pressing and ultra-high temperature oil shaft kiln calcination.
