Improvement of production technology aluminum alloys in the mixers of the casting compartment using software and instrument system for modeling and optimization

The article discusses the features of the technological process for the production of aluminum alloys of various grades in electric resistance mixers in the foundry department of an industrial enterprise. The process of obtaining aluminum alloys with a given chemical composition is a complex physical and chemical process that includes sequential mixing of raw aluminum obtained by electrolysis and its interaction with various master alloys and fluxes. At this stage, the formation of the required chemical composition and quality of aluminum alloys occurs through refining and degassing of the melt. This stage of production is associated with the presence of an excessive number of corrective actions due to the multitasking and multifactorial nature of the metallurgical process, which leads to an increase in the melt preparation time, a decrease in the productivity of the electric resistance mixer and an increase in the cost per unit of finished product. Improving the technological process of forming aluminum alloys is associated with the cost of conducting experimental studies. In this regard, mathematical modeling with the use of software and instrumental systems is of great importance, which ensures the high quality of aluminum alloys as a result of predicting the final parameters of the chemical composition. Therefore, within the framework of the intensive digital transformation of the metallurgical industry, the development and industrial application of software tools that allow optimizing the technological process of producing aluminum alloys, reducing energy and material costs, as well as increasing the productivity of foundry mixers is relevant.
