Prediction of the Temperature of Liquid Aluminum and the Dissolved Hydrogen Content in Liquid Aluminum with a Machine Learning Approach

Abstract: In aluminum casting, the temperature of liquid aluminum and the dissolved hydrogen density are crucial factors to be controlled for the purpose of both quality control of molten metal and cost efficiency. However, the empirical and numerical approaches to predict these parameters are quite complex and time consuming, and it is necessary to develop an alternative method for rapid prediction with a small number of experiments. In this study, the machine learning models were developed to predict the temperature o… Show more

“…The lowest MSE value was also obtained for this model (MSE = 85.36). The linear regression model can be a proper model to predict if the accuracy is sufficient, which is known as one of the simplest machine learning models [50]. As their comparison shows, the best results were obtained for the GPR model.…”

“…The regression trees that we will use in the current study are binary, and every step in prediction included examining the value of one predictor parameter. The lowest leaf size will be 4, 12, and 36 for fine trees, medium trees, and coarse trees, respectively (Kim et al, 2020).…”

“…There are a large number of aluminum products in the manufacturing industry [2][3][4][5][6][7][8], and efficient production process control can reduce production costs and improve product quality. In the process of manufacturing casting products, the temperature control of molten aluminum is a key factor [3,[8][9][10][11]. In this sense, it is of great significance to control the temperature of molten aluminum to improve the performance of castings.…”
