DESCRIPTION
Currently in the smelting process of aluminum ingots and special steel, the use of silicon metal 97 as a smelting material has become to normal. Silicon metal 97 is also called the off-grade silicon and industrial silicon, which is a non-ferrous alloy additive. Usually the main raw materials required for the production of silicon metal 97 are silica and semi-choke which are made by heating and smelting the raw materials in an electric furnace. Silicon metal 97 is rich in silicon, up to 98.99%, so it can play a better role in the production of aluminum ingots and special steel.
