降低炼焦配煤成本工业试验

Industrial experiments of decreasing cost of coking coal blending

为了在稳定焦炭质量的条件下降低炼焦配煤成本,西昌钢钒有限公司与攀钢集团研究院一起设计降低炼焦配煤成本200kg焦炉炼焦试验方案并进行试验。试验表明,在配煤中配加低价的气煤和瘦煤后,焦炭质量可达到要求。在200kg焦炉炼焦试验的基础上选择方案3开展工业试验研究,研究结果表明,在大幅增加气煤和瘦煤配比的情况下,焦炭反应后强度为61.57%,M40大于90%,达到了西昌钢钒对捣固焦炭质量的要求,且试验期配煤成本比基准期配煤成本下降39.24元/t,降成本效果明显。

In order to reduce the cost of coking coal blending under the stable stage of coke quality,the experiment plan on 200 kg coke-oven was designed by the Xichang Steel and Vanadium and Pangang Group Research Institute,and the experiments were carried out.The results showed that with introducing gas coal and lean coal of low price in the coal blending process,the coke quality could meet the requirements.On the basis of the results of experiments on200 kg coke-oven,the scheme 3were chosen to carry out the industrial experiment.The results of industrial tests showed that the coke′s CSR was 61.57%and M40 was more than 90%in the case of a substantial increase in the ratio of gas coal and lean coal,which met the requirement of stamping coke quality in Xichang Steel and Vanadium.And the cost of the coking coal blending in the test period decreased by 39.24 yuan per ton compared with it in the benchmark period.Thus,it had obvious effect on cost reduction.
