How Steel is Made Steel Manufacturing Process – Mixer Direct

27/06/2019  When the bessemer method is used, pig iron is oxidized in a bessemer converter. This is used to oxidize the iron. As the iron is being oxidized, it remains at the right to temperature to keep the steel molten. During this process, impurities in the iron combine with the oxygen.

20/01/2017  To create pure steel, the products that go into it- lime, coke and iron ore- must be made into iron. These are all put into a blast furnace and melted down to create what is called molten iron or hot metal. The iron still has many impurities at this point, and they will have to be removed to ensure the metal is not brittle.

Magnetite - Wikipedia

The industrial catalyst is obtained from finely ground iron powder, which is usually obtained by reduction of high-purity magnetite. The pulverized iron metal is burnt (oxidized) to give magnetite or wüstite of a defined particle size. The magnetite (or wüstite) particles are then partially reduced, removing some of the oxygen in the process.
