摘　　要：研究了配煤粒度及添加沥青对无烟煤配合炼焦所得焦炭的界面结合状况的影响情况。结果表明,在配煤比、堆密度相同的情况下,适当降低装炉煤粒度,有利于界面结合。沥青在配料中对煤有不同程度的改质,从而增加了容惰性组合的能力和改善了界面结合状况。The effects of coal grains for coal blending and addition of pitch on the in-terface bonding of the coke from cokemaking with blend from anthracite are studied. The results show that at the same coal blending ratio and bulk density, the appropriate re-duction of coal grain size is favourable to interface bonding, the addition of pitch into the blend can modify coal in some degree and therefore the index of capacity for inerts is in-creased and interface bonding improved.
