摘要:

通过汇总和分析6.25m捣固焦炉的配煤结构、配合煤质量、加热制度等工艺控制条件,总结了适宜的推焦电流控制条件,配合煤指标需控制为焦肥煤≤55%、肥煤≤10%、Vdaf≥28%、Rmax=1.11~1.17、b/a=15~30、G值≤80、Y值≤16,以稳定焦炉生产。

Abstract:

By summerizing and analyzing the process control conditions of  6.25m stamp-charging battery such as coal belending structrue, quality of coal blended and heating schedule, this essay concludes suitable pushing current control conditions. In order to have stable operation. It is required to control the blended coal as per the follwing indexes, coking fat coal≤55%, fat coal≤10%, Vdaf≥28%, Rmax=1.11~1.17, b/a=15~30, G≤80, Y≤16.
