摘要
本研究在国内外首次研制了镍冶炼矿热电炉的三维电、热解析模型及计算机仿真软件,并通过现场测试和模型试验对金川16500kVA矿热电炉的仿真结果进行了验证。运用这一模型可快速、直观地计算并显示出电炉内部各处的电压、电流、功率、温度及热流分布,计算出电炉的操作电阻、化料量、电能单耗及热平衡。依据这些信息可对电炉的结构参数与操作条件进行技术经济评价与优化。
A three dimensional mathematical model of a nickel matte smelting furnace is developed for the first time in this paper and the simulating results for a 16 500 kVA smelter in Jinchuan are in agree- ment with the data obtained from this furnace and its physical model. The software of the model can be used to plot in visualized graphical formats the distributions of the electrical current, voltage, power density, temperature and heat flux in the furnace, so as to calcu- late the electrode-to-grouud resistance of the bath as well as the output and the electric energy con- sumption of the operation. With this useful information the model may be considered as a new tool for evaluating and optimizing the design and operation of the furnace.
