Abstract

In the process of LF furnace steelmaking, alloys need to be added in the tapping process for deoxidation and composition fine-tuning. Aiming at the problem of alloy addition, an alloy charging optimization model is designed. First, use the radial basis function (RBF) neural network to establish the alloy yield prediction model; then use the improved particle swarm (PSO) algorithm to optimize the radial basis function neural network, and obtain the optimal neural network weights and thresholds through training; finally use the actual production data is simulated, and the results show that the model effectively improves the prediction accuracy of alloy yield.
