Silicon Slag
What is silicon slag?
Silicon slag is a by-product of smelting metal silicon and ferrosilicon.It is a kind of scum floating on the furnace in the process of smelting silicon.It's content is from 45% to 70%,and the rest are C,S,P,Al,Fe,Ca. It is much cheaper than purity silicon metal. Instead of using ferrosilicon for steelmaking, it can reduce the cost.
How to produce Silicon Slag ?
Silica slag comes from the residue of ore refining, It is a by-product of silicon metal and Ferro silicon production process. It also can be deeply processed into briquette, lump, powder to improve efficiency. Silicon slag is used for steel slag refining pig iron, ordinary casting, etc. The silicon slag can improve the furnace temperature and increase the flow of molten iron.Performance,effective slag removal, increase markings, improve the toughness and cutting ability of castings.
What is the use of silicon slag?
Silicon slag is widely used in steel slag re-smelting iron and ordinary casting. It can improve the furnace temperature, dilute the molten iron, increase the fluidity of the molten iron, promote slag discharge, and increase the label. 1. Silicon slag can be used for refining, recrystallization and purification; 2. Effectively discharge slag, increase the label, improve the toughness of the casting and the cutting ability. Stainless steel manufacturers use silicon slag as a reducing agent in the process of refining stainless steel in an electric furnace to increase the rate and output;
Silicon slag can be used in steel mill instead of Ferro silicon .
Silicon slag is used for steel slag refining iron, ordinary casting, etc. The silicon slag can improve the furnace temperature and increase the flow of molten iron.Performance, effective slag removal, increase markings, improve the toughness and cutting ability of castings. According to its content, silicon slag can be divided into silicon slag 30, silicon slag 40, silicon slag 50 and other silicon slags. Among them, 50 silicon slag is the most advantageous and widely used. It has been well received by customers and its production scale is also expanding. Next, Hensfate Metal will focus on the use of 50 silicon slag for you, and hope that our customers can help when choosing products. The silicon slag can be recrystallized and purified during this process; Effectively discharge slag, improve the toughness and cutting ability of castings, and can also be used as a reducing agent in the production of stainless steel; Silicon slag alloy can participate in the purification process of other ferroalloy products, which can effectively improve the silicon purity of ferroalloy products, resulting in better product quality and better results; The addition of silicon slag alloy in steelmaking has the effect of increasing the furnace temperature, which can provide a stable high temperature environment for the smelted materials and make the smelting more thorough.
