Xinhua News Agency, Harbin, December 30th The 15,000-ton heavy-duty free forging hydraulic press with the largest tonnage and the most advanced technology designed and manufactured by China First Heavy Machinery Group Co., Ltd. was successfully tested on December 30th. Zeng Peiyan, member of the Political Bureau of the CPC Central Committee and vice premier of the State Council, sent a congratulatory letter to emphasize the successful commissioning and commissioning of the 15,000-ton hydraulic press. It is another major equipment achievement after the successful development of a 10,000-ton hydraulic press in 1958. It will provide important hardware conditions for the production of large forgings. Greatly improving the level of equipment manufacturing in the power, metallurgy, petrochemical and shipbuilding industries is of great significance for accelerating the revitalization of major equipment manufacturing industries. Zeng Peiyan said that Yizhong Group, as a key backbone enterprise in China's equipment manufacturing industry, has provided a large number of technical equipment for national economic construction and national defense security over the years and made outstanding contributions. In recent years, driven by the national implementation of the strategy of revitalizing the old industrial bases in Northeast China and accelerating the revitalization of the equipment manufacturing industry, enterprises have accelerated technological transformation and strived to improve their independent innovation capabilities and achieved remarkable results. Zeng Peiyan pointed out that during the "11th Five-Year Plan" period, China's national economy will continue to maintain rapid development, industrial structure will accelerate, and demand for major technical equipment market will be strong. He hopes that Yizhong Group will fully implement the scientific development concept and accelerate the development of equipment manufacturing in accordance with the country. Strategic deployment, taking the opportunity of the successful development of 15,000 tons of hydraulic press, seize the opportunity, develop and innovate, further improve the technical level, strive to enhance manufacturing capacity, and build a world-class large-scale casting and forging steel and heavy equipment production base as soon as possible, in order to accelerate the revitalization of China The equipment manufacturing industry makes a greater contribution. At present, there are 3 forging hydraulic presses with more than 10,000 tons in China, all built in the 50s and 60s of the last century. These hydraulic presses have low production efficiency, and the grades and precision of the forged parts produced are difficult to meet the requirements for the production of large forgings in key areas. Internationally, Russia and Romania each have a 15,000-ton hydraulic press. One heavy group's new 15,000-ton hydraulic press not only surpasses the existing domestic hydraulic press, but also becomes one of the world's largest tonnage hydraulic presses, and at the level of the mainframe structure and control system. It has also been comprehensively improved and is currently the most advanced heavy-duty free forging hydraulic press in the world. The construction project of 15,000 tons of hydraulic press started from the beginning of 2002. All development work was independently completed by the technical staff of Yizhong Group, with all independent intellectual property rights. After the operation machine matched with the hydraulic press is put into production, Yizhong Group will increase the output of forgings by 70,000 tons per year, with an output value of nearly 400 million yuan.
