Abstract
In a method of producing coke for metallurgy by carbonizing a coal blend obtained by blending plural raw coals in an coke oven, a coal blend containing not less than 60 wt % of a medium coking coal of middle coalification degree and low fluidity having an inert component content of not less than 30% is used as a coal charged into the coke oven, whereby a great amount of raw coal of a brand being cheap and easily available can be blended in a great amount and hence coke for metallurgy having an excellent quality such as strength or the like can be produced by blending few brands of coals as compared with a coal blend of many brands.
