Pb-Sn合金连续结晶分离过程的模型化与优化

MODELLING AND OPTIMIZATION OF ELECTRIC-HEATING CONTINUOUS CRYSTALLIZER IN Pb-Sn SEPARATING PROCESS

电热连续结晶机是实现粗锡脱铅精炼的关键设备。本文在冶金热力学和动力学的基础之上,从系统简化和耦合分析的角度出发,探讨了结晶分离过程中物料因素和能量因素与产品产量、质量的相互关系,所得的静态数学模型与实际生产是吻合的。在此基础上,作者提出了一种综合收益目标函数并探讨了结晶分离过程的静态优化控制策略,所导出的有关优化控制算法经计算机仿真证明是实用可行的。本文工作将该领域的研究工作由定性分析引入到定量研究,同时为该设备的自动化奠定理论基础。

The electric-heating continuous crystallizer is an important equipment in tin metallurgical processes. In terms of thermodynamics and metallurgi cal dynamics, applying the method of system simplification and relation analysis, the effect of matter factor and energy factor in the crystalliza tion process on the quality and quantity of the product is determined. The steady mathematic model can simulate the practical process. Based on the steady model, the authors choose the integrative benefit function and de...
