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。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 suit- able 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%, Vbf≥28%. Rmax=1.11- 1.17, b/a=15-30, G≤80, Y≤16.
