| Abstract: |
| Based on practical copper flash smelting and control process, neural network model was studied in copper flash smelting process on-line control. Based on analysis of the effecting factors on solvent rate, oxygen consumption of melting, and air volume of reaction tower, a back propagation neural network prediction model was presented to predict the above parameters. BP neural network models with input vector containing only main elements and impurity elements in concern were established. The simulative results show that the maximum relative error between output value and actual value is less than 1.0%. Output value accords with practical data very well. The mode including impurity elements in input parameters has higher calculation accuracy. |
