Ferrosilicon natural block
product description
This product is used as a deoxidizer or alloying element additive. The silicon iron is 72%, 75%, etc. The silicon content is silicon, steel and coke. The silicon is melted at 1500-1800 degrees. In the molten iron, a ferroalloy is formed. It is an important alloy variety in the smelting industry.
Characteristics
1. Used as a deoxidizer and alloying agent in the steelmaking industry.
2. Used as an inoculant and spheroidizing agent in the cast iron industry. Cast iron is an important metal material in modern industry. It is cheaper than steel, easy to melt and smelt, has excellent casting properties and much better seismic resistance than steel. In particular, ductile iron has mechanical properties that are at or near the mechanical properties of steel. Adding a certain amount of ferrosilicon to cast iron can prevent the formation of carbon in iron and promote the precipitation and spheroidization of graphite. Therefore, in the production of ductile iron, ferrosilicon is an important inoculant (helping to precipitate graphite) and spheroidizing agent. .
3. Used as a reducing agent in the production of ferroalloys. Not only is the chemical affinity between silicon and oxygen high, but the high silicon ferrosilicon has a very low carbon content. Therefore, high silicon ferrosilicon (or siliceous alloy) is a commonly used reducing agent in the production of low carbon iron alloys in the iron alloy
