What is Slag Cement? (with pictures) - wiseGEEK

Jun 16, 2020 · Slag cement, often called ground granulated blast-furnace slag (GGBFS), is one of the most consistent cementitious materials used in concrete. It is actually a byproduct of iron production. When the iron is processed using a blast furnace, slag and iron both collect at the bottom of the furnace.The molten slag must first be separated from the molten iron.

Steelmaking - Wikipedia

Steelmaking is the process of producing steel from iron ore and/or scrap.In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel. ...

Dross - Wikipedia

Dross is a mass of solid impurities floating on a molten metal or dispersed in the metal, such as in wrought iron. It forms on the surface of low-melting-point metals such as tin, lead, zinc or aluminium or alloys by oxidation of the metal.For higher melting point metals such as steel, oxidized impurities melt and float making them easy to pour off.
