Radial-Axial Rolling, Solving Deformation and Misalignment Issues
We use radial-axial integral rolling technology to manufacture hydroelectric yoke forgings, overcoming the inherent defects of the traditional steel plate splicing model:
More Stable Performance: Through the integrated forming process, we can solve the deformation, misalignment, and other issues caused by traditional steel plate splicing, ensuring that hydroelectric products have safer and more stable performance.
Better Overall Stiffness: This forming method gives hydroelectric yoke products excellent overall stiffness, which can significantly improve product processing and installation accuracy. This is particularly important for generator motors that need to start and stop frequently and quickly switch between pumping and power generation states.
More Flexible Dimensions: The radial-axial rolling technology breaks through the limitations of traditional free forging press opening space on forging dimensions, enabling the production of extra-large forgings with a diameter exceeding 10 meters and a weight exceeding 300 tons. This has opened up new design ideas for many large pumped storage power plants in China.
Accumulated Experience in Large Projects
Iraeta has long-standing expertise in the hydroelectric field. Since 2019, Iraeta has successively provided 26 integral yoke forgings for the Fengning project, the world's largest pumped storage power plant at that time.
Subsequently, we have provided various forgings such as yoke discs, ring plates, mirror plates, cover flanges, and center bodies for multiple projects, including the Jinsha River Yinjiang tubular turbine unit, Zhejiang Jinyun Pumped Storage Power Plant, Heilongjiang Huanggou Pumped Storage Power Plant, Guangdong Yangjiang Pumped Storage Power Plant, and Guangxi Datengxia Hydropower Station.
These projects are widely distributed and cover different types, fully demonstrating the durability of Iraeta' products in extreme environments such as high speed and high centrifugal force.
Customized Solutions
We pursue not only adaptability to meet customer needs but also aim to achieve performance breakthroughs.
Based on deep technical expertise and industry insights, we have established a full-chain customized service system covering material research and development, process design, and precision manufacturing.
For core parameters such as water head drop and installed capacity of different power plants, we conduct in-depth analysis of working condition characteristics to tailor exclusive solutions for key components such as large buckets, runners, retaining rings, and lower rings, thereby ensuring the stable operation of high water head and large capacity units.
