Production Methods of Ferro Silicon

Traditional smelting method: Uses silica, steel scraps, and carbon-based reducing agents such as metallurgical coke, gas coke, semi-coke, lignite, or anthracite. The materials are smelted in a submerged arc furnace to produce ferrosilicon.

New smelting method: Designed to produce ferrosilicon powder at lower costs, reducing or eliminating the need for metallurgical coke and steel scraps. Primary raw materials include ferrosilicon coke and silica, with optimized raw material ratios to enhance product quality and reduce production costs.

Packing and Shipping of Ferro Silicon

Packing	Jumbo bags or as per customer requirements
Shipping	Shipped by road, sea, rail

FAQ

Q: What is ferro silicon used for?

A: Ferrosilicon is also used for manufacture of metallic silicon, corrosion-resistant and high temperature-resistant ferrous silicon alloys and silicon steel for electric motors and transformer cores. In the manufacture of cast iron, ferrosilicon is used for inoculation of the iron to accelerate graphitization.

Q: Where is ferro silicon found?

A: Ferrosilicon is produced by reduction of silica or sand with coke in the presence of iron. Typical sources of iron are scrap iron or millscale. Ferrosilicons with silicon content up to about 15% are made in blast furnaces lined with acid fire bricks.

Q: What are the raw materials for ferro silicon?

A: Main raw materials for Ferro Silicon production are quartz, charcoal and mill scale.

Q: How to make ferrosilicon?

A: The process of Ferrosilicon production involves the reduction of sand or silica (Si) with coke / coal (C), and then reacting it with iron (Fe) which can be obtained from scraps. The Carbon in the coal is required to remove the oxygen, leaving a pure Silicon and Iron product.

Q: What are the grades of ferrosilicon?

A: There are two standard grades of ferrosilicon, with one grade approximately 50 percent silicon and the other 75 percent silicon by weight. 2 The purity of silicon metal generally ranges from 96 to 99 percent.
