Ferrosilicon is a kind of ferrosilicon alloy made by electric smelting with coke, steel scrap, quartz (or silica) as raw material.

Size: 0-1mm, 1-3mm, 3-10mm, 10-50mm, 50-100mm or customized.


(1) used as deoxidizer and alloy agent in steelmaking industry.

(2) it is used as inoculation agent and spheroidizing agent in cast iron industry. Adding a certain amount of ferrosilicon in the process of cast iron can prevent the formation of carbide in iron and promote the precipitation and spheroidization of graphite.

(3) 75# ferrosilicon is the main raw material for the production of magnesium, which consumes about 1.1 tons.

(4) the pulverized or atomized ferrosilicon powder can be used as suspended phase in the mineral processing industry and as suspended phase in the welding rod manufacturing industry
