  • Can We Make Steel Without Coal  Coal Action

    Can We Make Steel Without Coal Coal Action

    Why is coal used to make iron and steel Firstly coal is converted to lump coke in a coking oven. A particular rank of coal, known as coking coal, is required to make the preferred quality of coke. Then raw iron is made by reducing removing the oxygen from iron ore iron oxide by reacting it at high temperature with coke in a blast.
