Steel Making Raw Material

Description of Steel Raw Material
Steel is one kind of alloy, made of iron and carbon. The carbon content is usually
less than two percent and for manganese, silicon, phosphorus, sulfur, and oxygen，
the the content is even smaller. Steel is the most important engineering and
building materials in the world. In the steelmaking process, the impurities, such
as nitrogen, silicon, phosphorus, sulfur and excess carbon (which is the most
important impurities) are removed from the source iron. To produce different
grades of steel, some different alloying elements such as manganese, nickel,
chromium, carbon, and vanadium need to add.

The Steel-making Process
There are two main business processes for steelmaking: blast furnace basic oxygen
steelmaking (using blast furnace liquid pig iron and scrap as the main feedstock)
and electric arc furnace (EAF) steelmaking, which uses scrap or direct reduced
iron (DRI) as the main feedstock. Oxygen steelmaking provides fuel mainly through
the exothermic properties of the reaction inside the vessel. Instead, in EAF
steelmaking, electrical energy is used to melt solid waste and/or DRI materials.
In recent years, with more chemical energy introduced into the process, the
development of EAF steelmaking technology has approached that of oxygen
steelmaking.

The main difference between routes is the type of raw material they consume. For
the BF-BOF route, it is mainly iron ore, coal, and recycled steel, while the EAF
route uses recycled steel and electricity to produce steel. Depending on the
configuration of the plant and the availability of recycled steel, other metallic
iron sources such as direct reduced iron (DRI) or molten iron can also be used in
the EAF route. Depending on the configuration of the plant and the availability of
recycled steel, other metallic iron sources such as direct reduced iron (DRI) or
molten iron can also be used in the EAF route.

The principle of steel-making is to use oxygen or iron oxide to remove the excess
carbon and other impurities contained in pig iron into gas or slag under high
temperature.
