Temperature prediction of titanium concentrate by microwave heating based on one dimensional convolutional neural network

Based on the research of microwave carbothermal reduction of low grade titanium concentrate, it is of great significance to accurately predict the temperature of microwave heating materials for improving the safety and reliability of the heating process. For the process temperature prediction of microwave heating titanium concentrate by microwave input power, heating time, initial temperature, three factors as input of neural network, builds a one-dimensional convolutional neural network predictive model, the root mean square error and coefficient of determination of the predicted results were 1.4527, 0.9927 and 6.0355, 0.8734 and 6.5986 and 0.8486, respectively, compared with the predicted results of the thermal effective energy transfer model and the general transfer model. The results show that the model can effectively predict the results and provide theoretical guidance for the subsequent production process.
