The BOS process uses pure oxygen, injected by a lance, for refining the relatively impure hot metal (and scrap is used for temperature control). The electric arc furnace uses primarily electrical energy to supply heat to melt scrap steel, sponge iron, or mixtures of scrap and other iron units. Compared to the BOS process, the EAF requires

Steel Manufacturing Process The steel manufacturing process can be divided into six steps: Making the iron, primary steelmaking, secondary steelmaking, casting, primary forming, and secondary forming. Step 1: Making the Iron. Steel is a metal alloy made of iron and carbon. Thus, the steel manufacturing process starts by making iron.

Steel is made from iron ore, which can be found in the earth's crust at many locations. In some places in Australia, South America, India and Scandinavia, ore is close to the surface, making it easy to extract.

4. BASIC OXYGEN STEELMAKING • Around 71 % of steel is made by this process. • BOF process was developed in Austria in the early 1950s at the two Austrian steelworks at Linz and Donawitz and hence the BOF process is also called LD (first letters of the two cities) steel making. • basic oxygen steelmaking, which has liquid pig-iron from the blast …

#1. Making the Iron. Steel is a metal alloy made of iron and carbon. Thus, the steel manufacturing process starts by making iron. To do this, limestone, coke, and iron ore are combined and put into a blast furnace. The elements are melted together to create a hot metal known as molten iron. #2. Primary Steelmaking.

It involves two main steps: 1. Production of molten iron from iron oxides through reduction in rotary kilns using carbon monoxide produced from coal and limestone. This yields a product called RPCC that is around 70% metallic iron. 2. Steel making which involves removing impurities from the molten iron through oxidation and producing molten steel.
