为了使炼铜转炉达到节能降耗、提高炉寿的目的，必须严格控制转炉内造渣期和造铜期熔体温度．基于此，作者简化了转炉中所用的各种冷料的熔化过程，建立了熔化速率与熔化时间的动力学模型，并确定了模型中的各个参数的值．将该熔化模型用于“炼铜转炉优化操作智能决策支持系统”中，利用VC++开发了一套工业软件，根据软件中炉况监控界面提供的当前剩余热和当前熔体温度，系统自动告诉操作者每种冷料的最大加入量，操作者可以动态调整冷料加入量，从而达到将炉内熔体温度控制在合理范围之内的目的．生产实践结果表明，该模型的应用使转炉平均炉衬寿命由原来的213炉提高到235炉，在冷料量供应不足的情况下使冷料处理量增大了近8%．该模型的使用在类似的企业中可以推广使用．

To control the smelting temperature of the copper converter((1 250±10) ℃ in slag-making period, (1 180±10) ℃ in copper-making) and improve the life-cycle of the converter, the smelting process of cold materials is simplified in this paper and the dynamic models of smelting rate and smelting time are established. The parameters of the models are determined. The models are used in the Intellectual Decision Support System of the Operation- Optimization of copper converter. The software system automatically tells operators the maximum feeding of each cold material according to the current left heat and the melt temperature showed in the monitor interface of furnace conditions. Thus, the melt temperature can be controlled within a feasible limits. The practice shows that the application of the models makes the average life-cycle of the converter lining be improved from 213 furnace-times to 235 furnace-times and make the cold materials feeding improved by 8 percent under the condition that not enough cold materials are provided.
