SELECTION METHOD OF CAKING FILLER, AND MANUFACTURING METHOD OF HIGH STRENGTH COKE USING THE FILLER |
摘要 |
PROBLEM TO BE SOLVED: To provide a method for properly selecting a caking filler suitable for each type of coal in manufacturing of high strength coke; and a manufacturing method of a high strength coke using the filler.SOLUTION: By a testing method of swelling properties in accordance with JIS M8801, the maximum shrinkage temperature Tand the maximum expansion temperature Tof a caking coal are obtained. From premeasured mass decrease curves of a plurality of caking filler, the mass decrease rate of each caking filler in the temperature range of T-Tis obtained as a gas utilization rate. The selection method of caking filler includes selecting a caking filler having a gas utilization rate equal to or higher than the volatilization rate of caking coal in the temperature range of T-T. The manufacturing method of a high strength coke includes obtaining coke by adding the caking filler thus selected to caking coal. |
