1A Manufacturing Process for Iron and Steel

2019-6-13  The hot metal is decarburized to the required carbon content in the BOF. 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.
