Mathematical modeling of the current technological process of forming an aluminum melt in the mixer of the foundry department

Improving the existing technology for the production of aluminum and its alloys is still an urgent task. The search for a solution to the presented technological problem is directly related to improving the technical and economic indicators of production, as well as increasing the efficiency of the corresponding algorithms for modifying aluminum alloys. The use of a mathematical apparatus to formalize the features of the presented production process will ensure finding the most optimal option for the formation of established grades of aluminum alloys in the foundry department of an industrial enterprise. This becomes possible thanks to the conduct of an unlimited number of scientific experiments and empirical operations aimed at calculating the required values of the parameters for mixing raw aluminum from casting ladles. At the same time, it is possible to analyze the already obtained values of the concentrations of chemical elements of raw aluminum in casting ladles, taking into account the specified requirements of the order portfolio, in order to selectively modify the fundamental elements of the chemical composition of the formed grade of aluminum alloy. The software-algorithmic implementation of the presented mathematical model using modern high-performance devices and computers will ensure a higher competitiveness of finished products in the non-ferrous metals market due to a systematic reduction in the cost of producing a ton of metal and obtaining new practical results. Also, the formalization of the technological process and the development of a mathematical model of the investigated process will allow organizing initial training and professional retraining of technological personnel of an industrial enterprise. Carrying out career guidance activities and organizing the process of improving the qualifications of technological personnel are possible by setting up various options for the initial combinations of casting ladles and determining the initial conditions of the set technological problem, taking into account the current production features and the available set of available modifying materials. The result of this study is the development of a mathematical model of the process of forming an aluminum melt in a mixer in the foundry department, consisting of equations of heat and material balances, taking into account the physicochemical laws of the course of metallurgical processes based on the law of conservation of masses in relation to the selected heterogeneous system. In addition, it is worth noting that using mathematical modeling, it is possible to continuously monitor the most important indicators of the technological process based on similar mathematical models in order to further improve the existing software complex or information system of the enterprise to an independent automated control system and user decision-making.
