(Hereinafter referred to as “Tongyu Heavy Industry”) has successfully shipped the first pumped storage sub-flap whole-cast runner (Dongfang Electrical Machinery Zhaoqing Project), realizing 100 days of short-term delivery, which marks an important step in the development of key cast steel parts for pumped storage projects.
For this product, the company's technical team carried out detailed process planning, using 3D printing technology to replace the traditional wooden mold, solving the problem of difficult molding of this type of complex products, and significantly shortening the production preparation time. At the same time, through the designation of a complete technical program, take strict quality control measures to ensure the product quality (zero weld patch) excellence, casting finishing cycle shortened by 60%, to achieve the product's short cycle smooth delivery, and for the subsequent pumped storage projects to provide a rapid smart manufacturing mode can be promoted and utilized.
Runner components is the pumped storage power station “heart”, its efficient operation will directly enhance the grid peak shifting capacity and clean energy consumption level, to help achieve the “double carbon” goal, and the company's first sub-flap runner castings developed successfully, is the technology to attack the lean management of the The successful development of the company's first split-flap rotor castings is a concentrated manifestation of the technology and lean management. The company will also take this as a new starting point, and constantly improve the level of technological innovation, improve product quality, in order to promote the development of China's pumped storage industry, add color.
