Abstract: In response to challenges such as overcapacity in the steel industry, the “dual carbon” goals, the upgrading of customer customized demands, and the technological transformation of Industry 4.0, Xichang Vanadium and Titanium Steel has initiated the construction of a smart factory for high-quality vanadium-titanium steel. The aim is to achieve cost reduction, efficiency improvement, flexible production, and sustainable development through digital transformation. Addressing the problems of data isolation horizontally and attenuation vertically in the traditional pyramid architecture of information systems, Xichang Vanadium and Titanium Steel has carried out top-level architecture design, adjusted business, technical, data, and application architectures, and explored the migration of existing applications to a cloud-edge collaborative industrial Internet platform to achieve deep integration of systems and data. Focusing on scenarios such as “digital design of processes, dynamic optimization of processes, intelligent online detection, online operation monitoring, intelligent warehousing, real-time monitoring and emergency response of safety risks, environmental pollution monitoring and control, and supply chain optimization”, data empowerment has been carried out. A domestic largest-scale integrated control center for the iron-making area of vanadium-titanium magnetite smelting has been built, and a three-in-one digital system for consistent quality management has been constructed. Centering on the customer, the entire supply chain data and collaborative optimization from production to sales, distribution, and transportation have been integrated, significantly enhancing product quality and enterprise competitiveness.
