Steelmaking - Wikipedia

Today there are two major commercial processes for making steel, namely basic oxygen steelmaking, which has liquid pig-iron from the blast furnace and scrap steel as the main feed materials, and electric arc furnace (EAF) steelmaking, which uses scrap steel or direct reduced iron (DRI) as the main feed materials. Oxygen.

May 13, 2015 . In the blast furnace of the ironworks – with a ceramic tile lining – the reduction of iron ore to iron takes place by removing the oxygen from the iron oxide minerals . With scrap-based production, electric arc furnaces are mainly used for the melting of steel scrap, a process which demands electric energy.

scrap is used in blast furnaces,Raw materials - Jernkontoret

May 13, 2015 . Iron and steel scrap is used as a secondary raw material, both for scrap-based and ore-based steel production. The scrap is . oxide to iron. But the coke also has further functions: to act as a physical support material for the blast furnace charge, to raise the carbon content in the iron and to supply energy.

How is Steel Produced? | World Coal Association

During the iron-making process, a blast furnace is fed with the iron ore, coke and small quantities of fluxes (minerals, such as line, which are used to collect impurities). Air which is . In the basic oxygen furnace, the iron is combined with varying amounts of steel scrap (less than 30%) and small amounts of flux. A lance.

scrap is used in blast furnaces,How Steel Is Made | Metal Supermarkets

Jun 5, 2015 . To make steel, iron ore is heated and melted in furnaces where the impurities are removed and carbon added. Today, most steel is made using one of two processes: Blast Furnace; Electric Arc Furnace (EAF). Blast furnaces use mainly raw materials (iron ore, line and coke) with some scrap steel to.

6 Steel Industry | Separation Technologies for the Industries of the .

The second, and fastest growing, part of the U.S. steel industry is based on the electric arc furnace (EAF), which can melt steel scrap to make liquid steel without . The first step in this process is the conversion of coal to coke, a porous, strong, carbon-rich material used in blast furnaces to provide most of the reducing power.
