Which coals are used in steel mills? I was under the impression it would be coke? But why did the steel mill people say it was 3 medium coal? I'd like to ask the experts to enlighten me.

General steel plants are equipped with coking plants, to use the main coking coal, one-third of the coking coal, lean coal and part of the fat coal according to a certain proportion with the use of this industry in our industry is called "coal blending", in order to improve coking performance, increase the coke conversion index M10 and M40. in addition, the boilers of the steel plant steam and power generation plants use power coal, blast furnace blowing with blowing coal---anthracite and anthracite, and the boilers of the power plant are used in the steel plant. coal, blast furnace blowing with blowing coal --- anthracite and bituminous coal.

The answer upstairs is wrong, steelmaking does not use coke, ironmaking uses coke. Sorry, please correct.
