The Modern Steel Manufacturing Process - ThoughtCo

At high temperatures, oxygen is blown through the metal, which reduces the carbon content to between 0-1.5%. The EAF method, however, feeds recycled steel scrap through high-power electric arcs (with temperatures of up to 1,650 degrees Celsius) to melt the metal and convert it into high-quality steel. 4

Metal Forging Processes, Methods, and Applications | TFGUSA

Metal forging is the process in which metals are formed and shaped using compressive forces. The forces are delivered using hammering, pressing, or rolling. There are a number of forging processes – cold forging, warm forging, and hot forging – which are classified by the temperature of the metal being worked with.

Steel making process – ArcelorMittal

There are two main processes for producing steel: by means of a blast furnace (= indirect reduction) in combination with a converter, or by means of an electric furnace. In the former process, iron ore is the main raw material. In an electric furnace, scrap iron is used and occasionally also sponge iron. Sponge is an intermediate product, which ...

Basic Oxygen Furnace Steelmaking | Steel Technology

The Basic Oxygen Steelmaking process differs from the EAF is that BOF is self-sufficient in energy. The primary raw materials for the BOP are 70-80% liquid hot metal from the blast furnace and the steel scrap need to be balanced. These are charged into the Basic Oxygen Furnace (BOF) vessel. Oxygen (>99.5% pure) is "blown" into the BOF at ...

Steel Manufacturing Process

The molten steel is formulated to precise chemical compositions during the secondary refining processes. The refined steel is then cast into a variety of solid shapes usually by a continuous casting method. The solidified shapes are processed into finished goods by various processes, including hot rolling, cold rolling, annealing and coating.
