Abstract Scope |
A fusion ELM model based on ensemble learning was proposed to predict slab temperature. Combined with the actual production data of a steel mill, the integrated ELM, ELM, ANN, BP network is designed and the comparison test proves that the integrated ELM model has more advantages in the aspects of running time and prediction accuracy. The number of base models for integrating ELM model is determined to be 3, the number of hidden layer nodes is 20, and the neuron activation function Hardlim is the most suitable for steel mill data set. The results show that the average hit rate of the predicted temperature is 88.89% within ±5℃, and the MAE and RMSE of the predicted results are 2.46℃and 2.85℃respectively, indicating that the model has high accuracy and stability, and can be used to predict the casting slab temperature. |
