<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing formed coke by using low quality coal as a main ingredient of raw material coal that achieves surface breakage strength targeted in advance. <P>SOLUTION: The method for manufacturing formed coke comprises obtaining in advance test-formed coke under a plurality of test dry-distilling conditions where the average temperature-raising rate H.R.<SB POS="POST">400-500</SB>between a point of time when the temperature at the central part of formed coke reaches 400°C and a point of time when the temperature reaches 500°C is changed, measuring the surface breakage strength DI<SP POS="POST">150</SP><SB POS="POST">6</SB>of each test-formed coke, determining the relationship between H.R.<SB POS="POST">400-500</SB>and DI<SP POS="POST">150</SP><SB POS="POST">6</SB>, defining the correlation region where H.R.<SB POS="POST">400-500</SB>and DI<SP POS="POST">150</SP><SB POS="POST">6</SB>have a correlation with each other, and dry-distilling formed coke by setting H.R.<SB POS="POST">400-500</SB>so that the desired DI<SP POS="POST">150</SP><SB POS="POST">6</SB>is attained based on the correlation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
