发明名称 METHOD FOR MANUFACTURING HIGHLY REACTIVE COKE WITH HIGH STRENGTH USEFUL FOR BLAST FURNACE
摘要 PROBLEM TO BE SOLVED: To provide a method for manufacturing of highly reactive coke with high strength, having both of coke tumbler strength (TI<SB>6</SB><SP>400</SP>) and strength after the reaction (IRI<SB>25</SB>) on a reaction ratio of 25% in a reaction with CO<SB>2</SB>keeping a desired level or more without using much amount of caking coal or a caking material. SOLUTION: The method comprises use of only the coal with a middle degree of carbonization, containing a semi-fusinite exhibiting semi-melting characteristics of≥25 vol.% in a inert component and having a maximum reflecting power (Ro) of 0.9-1.1 and a maximum flow rate (MF (log)(ddpm))) of≥2.5 and of≤3.4 as the coking coal for charging into a coke oven.
