摘要： PROBLEM TO BE SOLVED: To manufacture coke with still higher strength by strongly crushing coal while suppressing the occurrence of fine particles as far as possible. SOLUTION: A manufacturing method of coke with high strength is characterized in that: coal of various grades and properties is grouped based on a relation between an Ai value and a size distribution index n value each defined by equation (2); the coal of each group is separately crushed with a throughput Q(t/h) satisfying equation (1) by using a crusher with a maximum throughput Q 0 (t/h); and charged into a coke oven separately or after having been compounded with coal which has been either crushed with another method or not been crushed. Q(t/h)≤Q 0 (t/h)×Ai(%) ... (1), Ai(%)=-p×n+q (p, q>0) ... (2). Here, p and q are constants, n is an exponent of size distribution determined by Rosin-Rammler's equation R=a×exp(-b×x n ), (R is a cumulative amount of crushed coal on a sieve with sieve opening (grain size) of x, a and b are constants), i is a group classification number.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing high strength coke solving problems in working environmental aspects and operating aspects of a coke oven. SOLUTION: This method for producing high strength coke comprises the steps of classifying blended coal into dust coal and coarse particulate coal, adding a caking filler material to at least the dust coal and charging into the coke oven. When the caking filler (a) is added to the dust coal, the amount of the caking filler in the dust coal is increased by such an amount that migrates to the coarse particulate coal side until the time for the blended coal to be charged into the coke oven.
