优化6m焦炉配煤方案,提高焦炭质量

Optimizing Blending Plan of 6m Coke Oven for Improving the Coke's Quality

济钢的两座6m焦炉投产初期焦炭强度波动,为此,以20kg小焦炉试验、岩相检测、焦炭反应性和反应后强度检测为主要试验手段,对新汶、官庄、圣佛、阳泉曲、新坡、两度、卜村等10多个煤种作了70余炉配煤炼焦试验,优化了配煤,完善了6m焦炉的用煤结构。

At the beginning of 6m coke oven starting-up, the coke＇s quality was not steady. Therefore, more than 70 times of coking test for blend were finished with many coal ranks such as Xinwen coal, Guanzhuang coal, Shengfu coal, Yangquanqu coal Xinpo coal, Liangdu coal,Pucun coal etc. by 20kg test oven, petrographic examination and using CRI and CSR examination as main means. The blending plan was optimized and the coke＇ s quality was improved.
