    摘要: Methods for pretreating and improving coking coal quality for producing blast-furnace coke by: (a) rapid-heating the coal charge in a fluidized-bed to a temperature range between not lower than 300° C. and not higher than the temperature at which the coal charge begins to soften, at a rate of 30 to 103 ° C./min., (b) classifying the rapid-heated coal charge to fine- and coarse-size coal, and then (c-1) briquetting the fine-size coal or (c-2) rapid-heating the fine- and coarse-size coal individually in a pneumatic preheater to a temperature range between not lower than 300° C. and not higher than the temperature at which the coal charge begins to soften, at a rate of 103 to 105 ° C./min., and (d) forming the fine-size coal.
