Waste reduction and implementation of environmentally safe and efficient production processes using high-silicon alloys of the Al – Si system

The modern metallurgical industry, especially in the field of ferrous metallurgy, faces significant challenges in improving energy efficiency, reducing waste volumes, and minimizing environmental impact. One of the promising directions is the use of high-silicon silumin alloys, which, due to their high strength, wear resistance, and thermal stability, are finding increasingly broad applications, including their capability for multiple recycling. This paper analyzes the composition and physico-mechanical properties of these alloys and their role in technological processes of ferrous metallurgy, such as smelting, casting, heat treatment, and mechanical processing. Innovative approaches aimed at reducing the energy intensity of production operations, minimizing waste, and creating closed production cycles are examined, which is particularly relevant for ferrous metallurgy, where waste volumes are traditionally high. Examples of application of high-silicon silumins in the production of casting molds, wear-resistant coatings, and structural materials for heavy industries are provided. Special attention is given to recycling and waste utilization technologies at metallurgical enterprises, contributing to lower production costs and increased competitiveness. Thus, the use of high-silicon silumin alloys demonstrates potential for shaping environmentally friendly, energy-efficient, and economically sustainable processes in ferrous metallurgy.
