摘　　要：济钢在120m3高炉炉役后期采取增设炉底冷却水管及钒钛矿护炉的措施,解决了护炉和强化冶炼的矛盾,在确保安全生产的基础上,通过采取优化炉料结构、推行大料批技术等强化冶炼措施,高炉炉役后期取得了较好的技术经济指标,利用系数达到了3.257t/(m3.d)。Measures such as setting up hearth bottom water-cooling pipe and adding schreyerite for furnace maintenance are used by Jigang to solve the conflict of furnace maintenance and strengthening smelting in the later stage of campaign. Based on safe production, the better technical and economy indexes are acquired by adopting strengthening smelting measures as optimizing the burden design and utilizing large material charge. The utilization coefficient of BF is up to 3.257 t/(m^3.d).
