Nonferrous smelting intelligent factory architecture and key technologies

Nonferrous smelting is a strategic raw-material industry that provides fundamental support for national economic development and defense-related industries. At present, the nonferrous smelting industry is confronted with increasingly complex raw materials, increasingly stringent environmental requirements, and an urgent need to reduce costs and improve efficiency. Therefore, it is imperative to promote the development of smelting plants toward high-end, intelligent, and green manufacturing. Focusing on the practical needs and challenges of intelligent factory construction in the nonferrous smelting industry, this paper designs a system and functional architecture based on an industrial Internet platform, proposes the key technologies for intelligent workshops featuring perception-decision-control-execution linkage as well as the key technologies for intelligent factories characterized by factor interconnection, centralized control, and business collaboration, clarifies an implementation pathway of progressing from points to lines, from lines to planes, and from planes to an integrated whole, and further puts forward a priority analysis strategy for implementation content by considering business dependency, technological maturity, economic feasibility, and urgency of demand. Finally, the paper discusses the expected outcomes and future development of intelligent factory construction in nonferrous smelting, with the aim of providing a reference for the planning and development of intelligent factories in this industry.
