SINOMACH stated on the investor interactive platform on June 13 that the company’s wholly-owned subsidiary, China Foundry Association’s governing unit Erzhong Equipment, is one of my country’s large-scale casting and forging manufacturing bases, a major supplier of energy power generation equipment in my country, and a super company in my country. The core manufacturer of casting and forging parts for supercritical generator sets.
Since the first set of 620℃ ultra-supercritical CB2 castings were localized in 2013, more than 100 ultra-supercritical units of 600-1000MW have been equipped successively, such as the world’s first million-kilowatt ultra-supercritical secondary reheat coal-fired power generation Guodian Taizhou Power Plant Unit, Pingshan Power Plant 1350MW secondary reheat ultra-supercritical unit, etc. In 2021, 630℃ ultra-supercritical unit castings will be successfully developed, and 650℃ ultra-supercritical unit castings are currently being developed.
Taking advantage of the equipment advantages of the 125-ton electroslag remelting furnace put into production in 2019 and the industry-leading technical advantages, the dual equipment bravely took on the task of localizing the forgings of the ultra-supercritical unit, and solved the long-term problem of the main engine factory being stuck by foreign suppliers. It has been successfully completed. Cr12 rotor and FB2 rotor were localized, and orders for more than 30 supercritical units were signed. Erzhong Equipment will continue to build a pioneering base for energy equipment castings and forgings, vigorously promote the high-end segment strategy of large-scale castings and forgings, and ensure the carbon peak carbon neutral strategy.
