the use of magnesium metal in metallurgical industry
Metal magnesium is an important metallurgical raw material, which is widely used in metallurgical industry. The following are the main uses of metallic magnesium in metallurgical industry:
1. Manufacture of light metal alloy: Magnesium can be alloyed with other metal elements to manufacture light metal alloy with good mechanical properties and corrosion resistance. For example, Al-Mg alloy with high strength and low density can be produced by alloying with aluminum alloy, which is widely used in automobile, aerospace, shipbuilding and other fields.
2. Casting process: Magnesium metal has good fluidity and solidification performance and is suitable for casting process. Through the production of magnesium alloy castings, castings with complex shapes and high precision can be manufactured. These castings are widely used in automobile, ship, mechanical equipment, engineering construction and other fields.
3. Non-ferrous metal smelting flux: Metal magnesium can be used as flux in non-ferrous metal smelting. Because of its high ignition point and strong oxidation, magnesium can absorb oxygen during melting, reduce the impurity content in non-ferrous metals and improve product quality.
4. iron and steel smelting deoxidizer: Magnesium can be used as deoxidizer in iron and steel smelting. Adding metallic magnesium in steel-making process can react with oxygen in slag to generate magnesium oxide, thus reducing the oxygen content in steel and improving the quality and performance of steel.
5. Manufacture of high-temperature alloy: Magnesium metal has good thermal stability and high-temperature corrosion resistance, and can be used to manufacture high-temperature alloy. Superalloys are widely used in aerospace, shipbuilding, nuclear industry and other fields, and can withstand complex working conditions such as high temperature, high pressure and corrosion.
details of magnesium metal
Metal magnesium has a melting point of 650 degrees Celsius and a boiling point of 1090 degrees Celsius. It has good electrical and thermal conductivity. Metal magnesium is also a good reflective material, which can reflect more than 80% of visible light, so it is often used to manufacture optical lenses, lighting devices and reflectors.
