配沥青改善焦炭热性能的试验研究

Experimental study on the improvement of coke thermal properties by adding pitch to coal

为改善焦炭质量,在炼焦煤中添加改质沥青进行试验研究。配加改质沥青后,CRI平均降低3.82%,CSR平均提高3.49%,焦炭质量指标明显提高。

The experimental study shows that coke quality can be improved by adding modified pitch to coking coal. After the application of modified pitch,it reduces CRI by an average of 3. 82% and raises CSR by an average of 3. 49%,a noticeable improvement in coke quality index.
