Products Details





1.The use of silicon metal 411 can be said to be very large for us. In the past, it was mainly used in traditional industries, such as metallurgy, and now it is also used in the information industry, such as semiconductors. So this mineral resource is becoming more and more important.
2.Silicon metal 411 is a mineral resource that exists in large quantities on the earth, but it is troublesome to mine and smelt, and requires advanced industrial technology and platforms. The mining and use of silicon metal also involves many other metals and technologies.
3.The process of chemical silicon metal 411 includes charge preparation, electric furnace melting, refining and casting of silicon, and crushing to remove slag inclusions. All raw materials are subjected to the necessary processing before the charge is prepared.
4.The silicon is crushed to a lump size of no more than 100mm in the jaw crusher, and the fragments less than 5mm are screened out and rinsed with water. Because the pieces melt in the furnace at the top of the furnace, the gas permeability of the charge is reduced, making the production process difficult. Petroleum coke has a high conductivity coefficient, and it is necessary to crush to a lump degree of no more than 10mm, and to control the amount of petroleum coke powder. Because it burns directly on the furnace mouth, it will cause a shortage of reducing agent.
