摘　　要：以2％的废焦油渣作粘结剂制备型煤，在40b小焦炉中进行配型煤炼焦试验研究，得出最佳配型煤比为20％，焦炭的冷热态强度均符合高炉冶炼要求，M40大于82％，焦炭反应后强度CSR在60％以上。The experimental study on coking by mixing moulded coal in 40kg small coke oven is made through using 2% waste tar residue as binder in preparation moulded coal. The results show that the optimal proportion of moulded coal is 20% in mixed coal and cold, hot strength of coke conform to the requirements of blast-furnace process, which index of M40 is more than 82 % and index of CSR is more than 60%.
