对太钢4号高炉炉役后期长期休风后快速恢复的操作经验进行了总结,主要是:休风前炉况基础较好,没有波动;休风料安排控制合理,全炉燃料比合适;加风的速度和开风口的时机把握比较好;恢复过程的操作参数调整比较到位;渣铁排放安排较好,能够吻合炉况恢复的进程。
The operating experience of rapid recovery after the long-time resting-off at the late stage of the second stage of the TISCO blast furnace was summarized. The main conclusions are as follows: The pre-break-before-ground condition is good and there is no fluctuation; The speed of the wind and the timing of the vent to grasp better; the recovery process of operating parameters to adjust more in place; slag iron emissions arrangements better able to meet the furnace recovery process.
