摘　　要：通过对开滦肥煤与外购1/3焦煤煤质指标的测定及对比评价,研究了少量1/3焦煤代替肥煤配煤炼焦的可能性。以40 kg焦炉炼焦法为基础,着重对焦炭的冷热态强度、孔结构及表观形貌等参数进行了测定和分析。研究结果表明,1/3焦煤与肥煤互配炼焦,前者比例应控制在10%以内,此时焦炭的CSR下降不明显,表面积与孔体积变化不大,焦炭的表观形貌亦不会出现明显劣化。Through determination and comparative evaluation of Kailuan fat coal and outsourcing 1/3 coking coal quality index, the possibility of mixing fat coal replaced by a small amount of 1/3 coking coal was studied. Based on the coal-coking method of 40 kg coke oven, the cold and hot strength of the coke, pore structure, apparent morphology and other parameters of coke were measured and analyzed emphatically. The results show that 1/3 coking coal and fat coal were blended for coking, the former ratio should be controlled within 10%, the coke has no significant decline of CSR in this case, and the specific surface area and pore volume change a little, the apparent morphology of coke is no obvious deterinration.
