Molten iron is produced in a blast furnace by the following steps: 1. Charge (solid iron ore, coke, and limestone) is constantly dumped into the top of the furnace. 2. A blast of hot air is blown into the furnace from the bottom. 3. Coke is the fuel that supplies additional heat, increasing the temperature of the charge. 4.

Steel making process. Steel is produced from iron ore or scrap. Iron ore is a mineral aggregate that can be converted economically into iron. The quality of the iron ore is mainly determined by its composition; a high iron content and low sulphur and phosphorus contents are favorable. Iron ore can be found all over the world, but its iron ...

Homepage /; About us 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.
Process of extracting metallic iron from iron-bearing minerals (ores) occurring in nature Iron ore: Hematite (Fe2O3) Magnetite (Fe3O4) Siderite (FeCO3) Laterite (mixed oxide of Fe & Al) Goethite (Fe.O.OH) Pyrites (FeS2) Oxide Oolitic (silicate + oxide + carbonate) MM 439: Iron and Steel Making Reduction of iron oxide to metallic iron
Combustion process. The iron in the processed ores must be dissolved out by chemical processes. This requires an element that binds oxygen more strongly than iron. ... More than 90 % of the pig iron is beeing tapped as white pig iron ("steel pig iron") and processed in liquid form in ironworks to the actual steel by special after-treatment ...
How steel is made. First, the raw materials, either iron ore or scrap iron (depending on the process), are converted into molten steel. The ore-based process uses a blast furnace or smelter and the scrap-based process uses an electric arc furnace. Next, the molten steel is poured and solidified in a continuous caster.
Interactive Steel Manufacturing Process AIST's Making, Shaping and Treating of Steel ® Wheel.

Steel making process ArcelorMittal is the world's leading steel and mining company. Our steel is at the heart of the modern world, forming the fabric of life from railways, to cars, to washing machines, to iconic towers and sculptures. We have diversified production facilities, using both basic oxygen furnaces and electric arc furnaces. From
The direct reduction process can serve as a complementary alternative to iron making in the steel industry. The process is regarded as environment friendly, with less dependence on high-grade metallurgical coke. During this process, the reduction of iron oxides is conducted in a solid state below the fusion temperature of pure Fe.
With this in mind, here are the 6 steps to modern steel production explained. Step 1 – The iron making process. As iron is the main component of steel it firstly needs to be made. Iron ore, lime, and coke are placed into a blast furnace and melted. The resulting liquid known as molten iron is then formed.
The production of steel at an integrated iron and steel plant is accomplished using several interrelated processes. The major operations are: (1) coke production, (2) sinter production, …
