摘要
受7.63 m干熄焦炉检修的影响,八高炉被迫由全干焦冶炼调整为全湿焦冶炼50天。重点分析了全湿焦冶炼期间对于高炉风量、煤气利用、消耗等的影响,高炉始终坚持以风为纲,增加中心布焦量,在保持中心气流畅通稳定的前提下调整边缘和中心两股气流的动态平衡,风量较干焦冶炼损失300~400 m^(3)/min,日均铁水产量损失500 t/d,但燃料比仍稳定在510.9 kg/t,整体炉况稳定顺行,各项指标稳定,为大型高炉湿焦冶炼提供了重要的参考借鉴意义。
Affected by the maintenance of a 7.63 m dry quenching coke oven, the No.8 blast furnace was forced to adjust from full dry coke smelting to full wet coke smelting for 50 days. The effect of full wet coke smelting on blast furnace air volume, gas utilization and consumption was analyzed. The blast furnace always insisted on taking wind as the core, increased the amount of coke in the center, and adjusted the dynamic balance between the edge and the center flow on the premise of keeping the center flow smooth and stable. The blast furnace air volume loss was 300-400 m^(3)/min compared with dry coke smelting, and the average daily hot metal yield losa was 500 t/d. However, the fuel ratio was still stable at 510.9 kg/t. The whole production of full wet coke in blast furnace was stable and smooth, and all indexes were stable, which provided an important reference for wet coke smelting in large blast furnace.
