en.Wedoany.com Reported - Lanzhou LS Heavy Equipment Co., Ltd. (referred to as "LS Heavy Equipment"), through its subsidiary Superalloy Company, recently completed the development of a key large cylindrical forging for high-end general machinery and delivered it to the customer on schedule. The cylindrical forging, weighing 45 tons per piece, is a core pressure-bearing component for general mechanical equipment, featuring large external dimensions and high wall thickness redundancy. This successful delivery marks the growing maturity of LS Heavy Equipment's manufacturing processes for large-scale forgings, with stable and reliable product quality, further solidifying the technical foundation for the industrialization of large cylindrical steel products in the high-end specialty sector.
LS Heavy Equipment is a leading Chinese manufacturer of energy equipment and large forgings, headquartered in Lanzhou New District, Gansu Province. Its predecessor, Lanzhou Petroleum and Chemical Machinery Plant, was one of the 156 key projects during China's First Five-Year Plan and was established in 1953. The company was listed on the Shanghai Stock Exchange in 2014 (stock code: 603169), with its main business covering the R&D, design, manufacturing, and engineering, procurement, and construction (EPC) of high-end equipment for sectors such as oil refining and chemicals, coal chemicals, nuclear power, and new energy. The Superalloy Company is a core subsidiary of LS Heavy Equipment, specializing in the R&D of specialty alloy materials and the production of large forgings, equipped with advanced facilities such as a 10,000-ton free forging press.
According to the Superalloy Company of LS Heavy Equipment, the cylindrical forging delivered this time had extremely high requirements in terms of external dimensions and wall thickness redundancy. Leveraging long-term technical expertise in the field of large cylindrical forging, the R&D team optimized process plans, utilized process simulation technology, and customized dedicated forming tooling. After multiple process trials, the team precisely adjusted key parameters such as forging deformation, holding time, and feed rate, addressing manufacturing challenges from the process design stage, including cylinder eccentricity, plastic deformation, and dimensional tolerance exceedances common in large forging forming. During production, the Superalloy Company strengthened full-process control over equipment maintenance, process coordination, and on-site operations. Through systematic process improvements and refined quality management, the product achieved compliance in dimensional accuracy, internal metallographic structure, and comprehensive mechanical properties, with all technical parameters meeting customer customization requirements.
The successful delivery of the product has laid a solid technical foundation for the mass production of thick-walled cylindrical forgings in high-end specialty steel by the Superalloy Company, also demonstrating its product manufacturing and contract fulfillment capabilities. The Superalloy Company stated that it will closely align with the demand for localization and independent development of high-end equipment, continue to tackle key core technologies in specialty alloy forging, iteratively improve the full-process intelligent manufacturing system, and support the upgrading of the high-end equipment industry with high-quality products and full-cycle services. This successful delivery holds positive significance for advancing China's independent manufacturing capabilities for large cylindrical forgings.
