Revitalization of high-end equipment manufacturing in China National Machinery Corporation
This forging is a key core component of a high head and large capacity impulse turbine, jointly developed by the group's subsidiary enterprise Erzhong (Deyang) Heavy Equipment Co., Ltd. (hereinafter referred to as "Erzhong Equipment") and other units. It will be used for the construction of Zhala Hydropower Station, the first hydropower station project in Tibet with an installed capacity of over one million kilowatts. Zhala Hydropower Station is the core power station of the Southeast Tibet Clean Energy Integration Base, and is the only hydropower project in China that can carry out the development and application demonstration of 500MW high head and large capacity impact type units at present. It is of great significance for achieving national energy security and the energy development strategy of "power transmission from Tibet to the outside".
This casting is developed by the Second Equipment Company, fully utilizing numerical simulation technology and lean management tools to carry out multi field coupling simulation calculations for filling, solidification, and stress, as well as full process value flow analysis. It has conquered key manufacturing technologies such as high-quality H/J grade heavy gas turbine thin-walled complex steel castings, providing important support for the localization of heavy gas turbines in China and ensuring energy security in China.
