The invention relates to a
coke oven coking method for improving a ratio of long
flame coal for chemical
coke. The method comprises the following steps: a, performing secondary crushing on long
flame coal, and mixing the long
flame coal with an
adhesive in a storage warehouse; b, performing pre-
grinding on the long flame coal mixed with the
adhesive, feeding the coal into a
coal blending chamber, improving a ratio of the long flame coal mixed with the
adhesive to 80 percent, adjusting a gas-fat coal ratio with high adhesiveness to 20 percent, and feeding the coal into a
crusher for crushing after mixing; c, performing primary water injection on the prepared mixed coal, crushing the coal in a
crusher chamber, performing secondary water injection on the crushed mixed coal, feeding coking coal into a charging car for tamping, so that the coking coal is smashed into a dense coal cake, and feeding the coal into a
carbonization chamber for performing high-temperature
dry distillation; and d, performing high-temperature
dry distillation on the coking coal, performing
coke quenching by adopting a dry method, and finally naturally cooling to obtain the chemical coke product. According to the method, low-cost
smelting and
chemical industry carbon materials can be produced, and the gap that
smelting and
chemical industry carbon materials are deficient is overcome.
