Steelmaking is the process for producing steel from iron ore and scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon are removed from the raw iron, and alloying elements such as manganese, nickel, chromium and vanadium are added to produce different grades of steel .
Basic oxygen steelmaking (BOS, BOP, BOF, or OSM), also known as Linz–Donawitz-steelmaking or the oxygen converter process is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel.
Steel Production: intro • Steel is one of the most important and widely used products in the world. Currently, the steel industry is undergoing a process of change.

After heating to steel making process flowchart rolling temperature in a reheating furnace, these castings are hot-worked to the required products.
Electric Arc Furnace (EAF) steel making (Figure 2). In the BOS process, molten iron is first produced by smelting iron ore in a blast furnace. This pig iron is then transferred to a steel making vessel called a converter. Some scrap steel (up to 30% of the charge) may also be added. High velocity oxygen is then blasted into the molten iron,
