Ferroalloys purposes: as a deoxidizer. Add some relatively strong in combination with oxygen, calcium, barium aluminosilicate Deoxidizer Tianjin, and its oxidation products can be successfully excluded Jilin barium calcium aluminosilicate Deoxidizer from liquid steel, so that the oxygen content of the molten steel to reduce the element. This process is called deoxy steel. Elements or alloys are used for deoxygenation called oxygen scavenger. Ferroalloy production technology trends: The computer controlled electric furnace smelting process. With a computer-controlled electric furnace production process, such as ingredients, feed on materials, electrode pressure release, electric power conditioning, cooling water and control the flue gas purification system, can improve furnace work load and work rate, to avoid errors caused by the furnace operating conditions Volatility and equipment accidents.
