Wusteel plates were used in the world's first 650℃ high-efficiency ultra-supercritical coal-fired power generation unit.
Recently, the world's first 650℃ high-efficiency ultra-supercritical coal-fired power generating unit—the Huaneng Yuhuan Power Plant Phase IV project—officially entered the full-scale construction phase, with the first batch of concrete poured. As a key project at the forefront of industry technology, the core equipment of this unit utilizes high-end boiler drum steel plates developed and manufactured by Hebei Iron & Steel Group Wusteel Company, used in critical structural components such as the boiler.
The boiler drum is a core pressure-bearing component of a thermal power generating unit, and its material properties directly affect the unit's operational safety, reliability, and energy efficiency. To meet the unit's long-term stable operation requirements under complex conditions of 650℃ high temperature and ultra-high pressure, Wusteel Company fully leveraged its technological research and development and production advantages, systematically optimizing production organization and process routes, and innovating key production technologies to address the practical challenges of complex on-site processes and tight delivery schedules.
The high-end boiler drum extra-thick plates supplied this time are characterized by high purity, uniform and dense microstructure, and excellent strength-toughness ratio. They particularly possess excellent comprehensive performance at medium and high temperatures, fully meeting the stringent standards for high-temperature resistance, creep resistance, and fatigue resistance required by high-efficiency ultra-supercritical units. Through precise control throughout the entire process, Wusteel not only ensured that the material performance fully met design requirements but also completed high-quality delivery 15 days ahead of schedule, effectively guaranteeing the project's construction schedule.
The successful application of this product marks another breakthrough for Wusteel in its high-end material R&D and supply capabilities in the energy steel sector, providing strong support for the development of advanced coal-fired power generation technology and the localization of major equipment in my country.
