1A Manufacturing Process for Iron and Steel

The main reaction in this process is the oxidization of the carbon in the hot metal by both pure oxygen gas (O 2) and iron oxide (Fe 2 O 3). The residual oxygen, after contributing to this decarburization reaction, remains in the molten steel.

The Steel Manufacturing Process - How is Steel Made?

10/4/2020· Using crucibles, or clay containers, the ironworkers would blend iron and charcoal pieces together in a high-temperature furnace. While cooking, the iron would melt and absorb carbon atoms from the charcoal. After cooling down, the crucibles contained what we now know as steel — an iron-carbon alloy.

Steel Production - American Iron and Steel Institute

Steel is primarily produced using one of two methods: Blast Furnace or Electric Arc Furnace. The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day.

How we make steel | British Steel

Making steel. At Scunthorpe, we use the Basic Oxygen Steelmaking (BOS) process – our modern convertors (or vessels) take a coined charge of scrap and liquid iron of up to 330 tonnes and convert this into steel in just 25 minutes. When the liquid iron arrives at the BOS Plant, it’s poured from the torpedoes into refractory-lined charging
