摘    要：通过开发的新型煤粉改性剂(ZZZ),对非炼焦煤改性和配煤炼焦。ZZZ能改善添加非炼焦煤后的焦炭质量,提高非炼焦煤的添加量,降低炼焦成本,扩大炼焦用煤资源。在2 kg试验焦炉开展非炼焦煤配煤炼焦试验,研究ZZZ对焦炭质量的影响。通过试验确定出白煤的添加粒度为全部小于3 mm,其中小于1 mm的占70%;非炼焦煤的最佳配入量为15%,其中白煤5%,喷吹烟煤10%,ZZZ的最优添加量为0.1%。由此方案炼得的焦炭质量达到南钢生产焦炭质量的水平。

Abstract: In order to blend non-coking coal in coal blending of coke-making,a new coal modifying additive(ZZZ),which can be applied to modify the non-coking coal’s ability,was developed.The results show that the coke’s quality is improved,the proportion of non-coking coal can be increased,the cost of coke is decreased and the coal resource for coke-making is expanded.The coking test of blended non-coking coal was carried out in 2 kg oven.The influence of ZZZ on coke’s quality was studied.The experimental results show that the optimal particle size is less than 3 mm,and 70% of them is less than 1 mm;the optimal ratio of non-coking coal is 15%,in detail,the anthracite and bitumite are 5% and 10% respectively;the ratio of ZZZ is about 0.1%.The coke’s quality can be up to the level of coke produced in Nanjing Iron and Steel Co.
