摘　　要：基于多相平衡原理、过程反应机理和MetCal软件平台,采用化学平衡常数法,建立铜阳极炉精炼过程热力学仿真模型和仿真系统。在典型生产工况条件下,模拟计算氧化期和还原期的产物组成和关键技术指标。结果表明:氧化期铜液中Cu含量的计算相对误差为0.14%,微量元素S、O的含量计算绝对误差分别为0.0057%和0.252%;还原期铜液中Cu含量相对误差为0.16%,S、O的含量计算绝对误差分别为0.0003%和0.002%,精炼渣Cu含量计算误差为4.69%,Pb、Zn、As、Sb和Bi等杂质元素在氧化期铜液与粗铜中的分配比计算结果与生产数据误差分别为2.82%、4.94%、6.24%、6.69%和0.07%。因此,所构建模型和计算系统能较好地反映铜阳极炉精炼过程的实际生产情况,具有精准预测该精炼过程和优化工艺参数的潜力,可有效指导铜阳极炉精炼过程的生产实践。Based on the principle of multiphase equilibrium,process reaction mechanism and MetCal software platform,the thermodynamic simulation model and simulation system of copper anode furnace refining process were established by chemical equilibrium constant method.Under typical production conditions,the product composition and key technical indexes of oxidation and reduction periods were simulated.The results show that the relative errors of Cu,S and O elements in copper liquid during oxidation stage are 0.14%,19.29%and 47.94%,respectively,the relative errors of Cu,S and O elements in copper liquid during reduction stage are 0.16%,5.47%and 1.15%,respectively,and the calculation error of Cu in refining slag is 4.69%.The distribution ratios of Pb,Zn,As,Sb and Bi in liquid copper and crude copper during oxidation are only 2.82%,4.94%,6.24%,6.69%and 0.07%,respectively.Therefore,the established model and calculation system can reflect the actual production of copper anode furnace refining process well,and has the potential to accurately predict the refining process and optimize the process parameters,and can effectively guide the production practice of copper anode furnace refining process.
