High Carbon Silicon HC Silicon

High carbon silicon (HCSi) is a type of ferroalloy that is made from silica, coke, and high-quality scrap steel or other raw materials. It has a high carbon content, typically ranging from 3% to 6%, and a silicon content of 50% or more.

HCSi is used as a reducing agent and alloying element in the production of steel and cast iron, as well as in the production of other ferroalloys such as ferrosilicon, magnesium ferrosilicon, and calcium silicide. It is also used as a deoxidizer and desulfurizing agent in steelmaking and as an inoculant in foundries.

Chemical Composition of High Carbon Silicon:

- Carbon (C): 3% - 6%
- Silicon (Si): 50% - 85%
- Phosphorus (P): 0.05% max
- Sulfur (S): 0.05% max
- Aluminum (Al): 1.5% max
- Calcium (Ca): 1.5% max
- Iron (Fe): balance
