The castings for hydropower station is mainly hydro-turbine blades. For machined surfaces of the castings, 100% area MT and 100% volume UT shall be carried out in accordance with “Specification for Inspection of Steel Castings for Hydraulic Machines” after finishing/grinding. In the actual use the quality of the products has won unanimous praise from the third-party inspection agency and the customers. Main products： Castings for mixed flow hydroturbine Castings for axial flow hydroturbine Application Martensitic stainless steel castings (such as runner ,the core component of hydropower equipment, runner crown, band, blade) and duplex stainless steel castings (such as pump casing, pump cover, guide vane) are strictly tested to meet the user's requirements. Features 01.The company has complete inspection and testing means. A variety of inspection and test, for instance, UT (Ultrasonic Test), MT (Magnetic Particle Test) and RT (Radiographic Test) can be carried out to meet the user's requirement for internal quality 02.The most real data have been mastered through summary, verification and optimization of a large amount of accumulation in the early stage. The casting product can be manufactured successfully just at one time thanks to the reliable, accurate and stable technical parameters. 03.Resin sand moulding is adopted. And the first-grade standard is used for all the patterns. For all the key areas the chromite sand, imported from South Africa, is used. In addition, the domestic best-quality crude sand, resin curing agent, paint and other raw materials are used.
