Iron and steelmaking process is energy intensive. Generally speaking, energy constitutes a significant portion of production cost, from 20% to 40%, according to the estimation from world steel association [7]. About 95% of energy for an integrated steelmaking plant comes from solid fuel (mainly coal), 3–4% from gaseous fuel and 1–2% from ...

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.Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel.The process is

During the basic oxygen process (BOP), oxygen blown into a combination of molten pig iron and scrap metal refines the product into steel. Some steelmakers blow oxygen from the top onto the surface of the melt, in a basic oxygen furnace.

Primary steelmaking has two methods: BOS (Basic Oxygen Furnace) and the more modern EAF (Electric Arc Furnace) methods. The BOS method adds recycled scrap steel to the molten iron in a converter. At high temperatures, oxygen is blown through the metal, which reduces the carbon content to between 0-1.5%.

Metal ores are generally oxides, sulfides, silicates (Table 12.3.1) or "native" metals (such as native copper) that are not commonly concentrated in the Earth's crust, or "noble" metals (not usually forming compounds) such as gold (Figure 12.3.1 ). The ores must be processed to extract the metals of interest from the waste rock and from

Steelmaking is the second step in producing steel from iron ore. In this stage, impurities such as sulfur, phosphorus, and excess carbon are removed from the raw iron, and alloying elements such as manganese, nickel, chromium, and vanadium are added to produce the exact steel required.
