Iron and Steel Manufacturing | Department of Energy

How Do We Decarbonize Iron and Steel Manufacturing? Traditional steel furnaces burn fossil fuels to reach the temperatures needed to smelt raw iron and carbon into steel. Process emissions are created when carbon is used to remove oxygen from iron ore, reducing it to pig iron, the key feedstock in the steel industry.

About Making steel Steel is made from iron ore, a compound of iron, oxygen and other minerals that occurs in nature. The raw materials for steelmaking are mined and then transformed into steel using two different processes: the blast furnace/basic oxygen furnace route, and the electric arc furnace route.

An introduction to steelmaking

Molten iron (called 'hot metal') produced in a blast furnace from iron ore, coking coal and steel scrap are the principal materials used in Basic Oxygen Steelmaking (BOS). Modern furnaces, or 'converters' take up to 350 tonnes of these materials and convert it into steel in around 15 minutes.

Infographic: the Iron and Steel Manufacturing Process

In the primary steelmaking step, liquid iron is converted into steel by the basic oxygen furnace (BOF) process, or by melting scrap steel or direct reduced iron (DRI) in an electric arc furnace. Secondary steelmaking is a refining process in which alloying metals are added and impurities are removed.

Steel production: from iron ore to functional industrial products. Sep 18, 2019 12:24:31 PM / by Victor Nieto Steel is an alloy of iron (Fe) and carbon (C) as well as some other alloying elements, depending on the required properties.

How is Steel Made? Steel Production Process (With PDF)

To produce steel first the iron ore is heated and melted in a furnace. The impurities are then removed from the molten iron. Carbon and other required alloying elements are added to make steel. Modernday steelmaking is highly improved and specialized. There are two processes that are widely popular for modernday steelmaking. They are:

Challenges and Outlines of Steelmaking toward the Year 2030 and ... MDPI

Demand for iron ore has been increasing with the increased production of iron and steel in developing countries such as India and China. However, the quality of iron ore has deteriorated over the years globally due to longterm mining. The lowgrade iron requires beneficiation before agglomerating for use in the ironmaking process.

Steel production process: what are the steps?

Step 1: Cargo preparation. In the steel industry, the raw material for steel production is iron ore. And in the first stage of the production process for this material, iron ore is agglomerated using lime and coke fines. At the end of this step, the resulting product is called sinter. The charcoal used is processed in the coke oven plant and ...

Process. Direct reduction processes can be divided roughly into two categories: gasbased, and coalbased. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).
