Blast Furnace | steeluniversity
An improved fluxing method for the galvanization of steel, particularly batch galvanization, is disclosed. In this process, a metallic element is deposited (for example, by electroless plating) on the surface of the steel sheet or other article prior to its being dipped in the galvanization bath. Preferred metals for use in this fluxing process are tin, copper, nickel, with tin being more ...

Iron and steel industry in the United States - Wikipedia
Lime is used as a fluxing agent in electric arc furnaces and basic oxygen furnaces. Lime removes impurities (silica, phosphorus, sulfur) from the steel being manufactured. The lime fuses with the impurities to form slag, which separates from the steel and is removed. This process improves the quality of the steel.

Business Outline - Asahi Seiren Co.,Ltd.
"Integrated" steel mills use a blast furnace to produce iron from iron ore, coke, and fluxing agents. A basic oxygen furnace (BOF) is then used to convert the molten iron, along with up to 30% steel scrap, into refined steel. "Minimills" use an electric arc furnace (EAF) to melt steel scrap and limited amounts
