ALUMINUM SHAVINGS USING THE TECHNOLOGY OF PRODUCING MODIFIERS FOR PROCESSING ALLOYS

Abstract

Modern metallurgy requires efficient and cost-effective methods to improve the properties of metal alloys. One promising approach is the development and implementation of new modifiers that not only enhance the mechanical characteristics of materials but also reduce their gas saturation and the number of non-metallic inclusions. This study explores the possibility of using aluminum chips as raw material for producing multicomponent modifiers, which helps to reduce production costs and improve the quality of cast aluminum alloys. The relevance of this research is driven by the need to optimize metallurgical processes in the context of limited energy resources. In traditional technologies, the deoxidation and modification of aluminum alloys are carried out using ingot aluminum, leading to significant energy consumption. The proposed method of recycling aluminum chips involves pressing them into briquettes, which provide a complex effect: deoxidizing, micro-alloying, and modifying the structure of the alloy. Experimental melts were conducted at PJSC "Dnipro Metallurgical Plant." During the tests, the influence of briquetted aluminum chips on the chemical composition, microstructure, and mechanical properties of the AL2 alloy was evaluated. Analysis results showed that the use of such modifiers ensures the uniform distribution of alloying elements and improves the performance characteristics of the final product. The scientific novelty of this study lies in proving the possibility of obtaining cast aluminum alloy AL2 from raw material consisting of crushed chips of the same metal. A detailed analysis of the technological process, chemical composition, and mechanical characteristics of the modified alloy was conducted for the first time, confirming the compliance of the obtained products with regulatory requirements. The study’s conclusions confirm the feasibility of implementing the developed technology in industrial production. The use of pressed briquettes made from aluminum chips significantly reduces energy costs, improves the quality of metal products, and increases production profitability, making the proposed method a promising solution for modern metallurgy.
