How does coke and coal play into steel making? -

2016-6-22  By the 1990s coal use became the norm. Typically coal preparation involves drying and grinding coal to tiny particles of less than 1mm for injection. The coal particles are separated from released gases in a cyclone. The waste gas, and sometimes natural gas, can be used for drying additional coal, which is generally kept below 6% moisture content.
