| description | 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 mu m is from 12 vol% to 15 vol% and a content ratio of pores having a diameter of from 10 mu m to 100 mu m is from 10 vol% to 15 vol% and the production method thereof. |
