Mg ingot, alias magnesium ingot, is a new type of lightweight and corrosion-resistant metal material developed in the 20th century. Its application is mainly concentrated in four major fields: magnesium alloy production, aluminum alloy production, steel desulfurization, aviation, and military industry. It is widely used in automobile manufacturing, light industry, metallurgy, chemical industry, electronics, instrument manufacturing, and other industries. Magnesium ingot is the lightest metal, the specific gravity of magnesium is about 2/3 of aluminum, and 1/4 of iron, with the advantages of lightweight, high strength, and high rigidity, etc. XLS Metals can produce high purity magnesium ingot with Mg ≥ 99.99%, is the world's largest magnesium ingot manufacturer, has a number of magnesium ingot production patent technology, can deliver various grades of magnesium ingot to the world, and provide professional technical We are the largest magnesium ingot manufacturer in the world.
The raw material of magnesium ingot is mainly calcined dolomite or magnesite. at present, the method of producing magnesium ingot is mainly based on the silicon-thermal reduction method and electrolysis method, calcined dolomite is put into a kiln and heated to 1100℃~1200℃, burned to calcined white (MgOCaO), and then ferrosilicon is added as reducing agent and fluorite as a catalyst, each raw material needs to be strictly Each raw material needs to be weighed and proportioned strictly, and then pressed into balls after grinding into powder. The pressed balls will be heated to 1200℃ in the reduction tank, and then kept under the vacuum condition of 13.3Pa for 8~10 hours, after which the magnesium oxide will be reduced to magnesium vapor, and the crude magnesium will be made after it is cooled. And then the crude magnesium will be heated to 710℃ and melted, and cast into magnesium ingots after refining with the melt. In order to make high purity magnesium ingots, the ingots need to be pickled, using sulfuric acid or nitric acid to clean the surface to remove the impurities on the surface of the ingots to make them beautiful.
