转炉应用助熔剂调渣的炼钢工艺研究

Study on steelmaking process with slag conditioner in converter

为了解决高炉铁水成分波动大、铁水冶炼过程很难实现稳态控制和冶炼操作标准化的问题,在转炉操作中引入助熔剂调渣操作。应用实践表明,转炉使用助熔剂调渣操作后,在吹炼过程中不喷溅、不返干、不粘枪,能够降低渣料消耗9.3 kg/t,金属吹损由11.60%降为10.01%,取得了显著的经济效果,达到了转炉冶炼顺行并降低生产成本的目的。

In order to solve problems of the great fluctuation of hot metal composition, the difficulty on steady-state control during steelmaking and the standardization for steelmaking operation, the slag adjusting process with a slag conditioner was introduced into converter steelmaking. The practice results showed that there were no splashing, no drying and no lance sticking during steelmaking by the slag adjusting process. The slag consumption reduced by 9.3 kg/t, and the metal loss reduced from 11.60 % to 10.01%. The smelting was smooth during steelmaking and the cost was reduced.
