基于响应曲面法优化氧化锌还原过程的研究
Optimization of zinc oxide reduction by response surface methodology
摘要
Abstract
Lead-zinc sinter was used as material and the effect of interaction between various factors on zinc oxide reduction process was studied by response surface methodology.Firstly,three process parameters of reduction temperature,reduction time and carbon addition amount were regarded as independent variables,and zinc reduction ratio was regarded as dependent variables.Optimization scheme with 3 factors and 5 levels was designed by response surface methodology based on central composite design.Secondly,optimized results were fitted,and regression model of znic oxide reduction was obtained.Finally,zinc reduction process was optimized by regression model.The results show that regression model is highly accurate,and zinc reduction ratio is influenced by reduction temperature and reduction time significantly.Under the optimized conditions of reduction temperature of 1 422 K,reduction time of 18.7 min,and 2.94 times of stoichiometric carbon,the predicted value of zinc reduction ratio is 94.13%,the experimental value is 94.36%,and the relative error of them is 0.24%.The optimization scheme is accurate and reliable,and the purpose of optimizing the process is achieved.关键词
