Sulphur removal in ironmaking and oxygen steelmaking 22 Mar 20 7 A sulphur balance is made for the steelmaking process of Tata Steel IJmuiden, the Netherlands. In this process, iron ore is reduced mainly by coke in the blast furnace BF . where it is oxidised by blowing pure oxy

Sulphur removal in ironmaking and oxygen steelmaking - Taylor usually most of the sulphur and some- times silicon and phosphorus as well is removed. The HM is then charged to the metal. In steel plants the basicity is calculated based on the weight ratio of basic oxides like CaO and MgO to a
