Hot iron and/or scrap metal are the primary metals to make steel in each process. Lime is injected to act as a fluxing agent. The lime combines with the silies, aluminum oxides, magnesium oxides, manganese oxides and ferrites to form steel furnace slag, commonly called steel slag. Slag is poured from the furnace in a molten state.
Slag generally comes from factories such as cement plants, thermal power plants, smelters, etc., mainly from the following sources: ① Oxides formed by oxygenation of various impurity elements (such as Si, Mn, P, etc.) contained in iron and steel (hot metal, scrap).

Steel recycling generates a small water impact. This impact is due to steel production from sources generating blast furnace slag which in turn is used in concrete production as a substitute for cement. When recycling is undertaken, this process no longer occurs, so concrete production must revert to cement in place of blast furnace slag.
