  • How does coke and coal play into steel making?

    Quality of coal In either coke or noncoked coal, the quality of the coal affects the quality of the steel Metallurgical coke is made from bituminous coals by a distillation process Ash deposited by the coal must be kept to a minimum, preferably below 10% of the original massprocessing, where process design changes are more likely to occur at 10 to 15year intervals Life expectancy may also vary from company to company within any given industry For example, in thermalcracking stills in the petroleum industry, some plants have standardized on Type 304 stainless steel, whereas, other plantsHigh Temperature Characteristics of Stainless Steel
