    摘要： Related to a blast furnace coke and a production method thereof. A coke having high reactivity and high strength in which coke strength, reactivity with CO2 and a pore size distribution are each at a desired level can be produced at a low cost by using a coal blend composed of a small number of brands comprising a large quantity of caking coal having medium rank and low fluidity. The blast furnace coke, being obtained by charging a coal blend comprising 60 wt % or more of semi-heavy caking coal having medium rank and low fluidity in which a content of inert component is 30 vol % or more in total or another coal blend comprising 60 wt % to 95 wt % of semi-heavy caking coal having medium rank and low fluidity in which mean reflectance (Ro) is 0.9 to 1.1 and maximum fluidity (MF) is less than 3.0 and the balance being a caking coal in which mean reflectance (Ro) exceeds 1.1 into a coke oven and coking the coal blend, which has a pore size distribution where a content ratio of pores having a diameter of less than 10 μm is from 12 vol % to 15 vol % and a content ratio of pores having a diameter of from 10 μm to 100 μm is from 10 vol % to 15 vol % and the production method thereof.

    摘要： 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.
