双底吹炼铅是一种典型的富氧强化熔池熔炼炼铅工艺，在协同处理铅基固废时，其实际生产操作相对于传统矿铅冶炼时更为复杂。为确保其生产状况处于稳定、经济的状态，对其工艺控制有了更高要求。采用MetCal desk冶金计算平台，基于冶炼过程物料平衡、热平衡及化学平衡的原理，建立了双底吹炼铅协同处理铅基固废工艺计算模型，模拟计算了双底吹炼铅工艺协同处理铅基固废工艺参数；同时通过反馈控制算法对模型进行修正及反馈控制，使其更符合实际生产情况，为现场工艺工程师实际生产操作提供指导，实现工艺过程的优化控制。

The double bottom blowing lead smelting is a representative kind of oxygen-enriched enhanced molten pool smelting process. Comparing with the traditional ore lead smelting, its production operation is more complex for coprocessing lead based solid waste. In order to ensure its production status in a stable and economic state, there are higher requirements for its process control. MetCal desk metallurgical computing platform was used to establish a calculation model for the double bottom blowing lead smelting process for coprocessing lead based solid waste through the principles of material balance, thermal balance and chemical balance in the smelting process. The process parameters of the double bottom blowing lead smelting process for coprocessing lead based solid waste were simulated and calculated. Meanwhile, the model was modified and controlled by the feedback control algorithm to make it more in line with the actual production situation, which can provide guidance for the actual production operation of the process engineers and realize the optimal control of the process.
