摘　　要：本文介绍了高铁水耗条件下转炉冶炼存在的问题,在综合评估炉型稳定维护的基础上,从留渣制度、供氧制度、造渣制度和终点控制制度等方面进行优化,不仅提高了过程控制的稳定性,转炉生产成本降低了3.42元。This article introduces the discussion of problems existing in converter smelting process under the conditions of the high molten iron ratio.Through optimizing the slag residual,oxygen supply,slag forming and terminal control of converter smelting on the basis of comprehensive assessment of furnace type stability maintenance.The practice showed that the optimized smelting process not only improved the stabilization of process control,but also the production costs per ton was reduced by 3.4 yuan.
