    How Does Coke And Coal Play Into Steel Making?

    Jun 22, 2016 The waste gas, and sometimes natural gas, can be used for drying additional coal, which is generally kept below 6 moisture content. Inert gases are used to minimize the risk of fire or ignition of the coal particles. Quality of coal In either coke or non coked coal, the quality of the coal affects the quality of the steel.
