From mcbfire.com:
When smelting sulfur-containing and easy to cut steel, ferrous sulfide is used to increase the sulfur content of the steel liquid.
The main component of ferrous sulfide is FeS, with a theoretical sulfur mass fraction of 36.4%. The melting point of pure FeS is 1190 ℃, and the density is 4.79/. The grade of industrial pure ferrous sulfide is FeS with a mass fraction of 80% to 85%. Using ferrous sulfide as an additive for sulfur has a higher recovery rate than using sulfur, and it does not pollute the environment. When using ferrous sulfide to increase sulfur, it can be directly added to the surface of the steel liquid, or wrapped with aluminum foil or iron sheet and inserted into the interior of the steel liquid or added to the steel flow or ladle. Its recovery rate is high and stable.
