【Major Equipment in the Chemical Engineering Sector】122 – 10-meter-diameter integral seamless forged transition section
Thread Content
The past decade has been a period of rapid development in China’s chemical industry, with the emergence of many new processes, products, and equipment. China’s chemical processing equipment has also seen significant progress, which has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and greater use of domestic equipment. We invite everyone to share their insights and engage in discussions, to cheer for Made in China and to support the development of chemical processing equipment! ***********************************
On April 18, 2018, the world’s largest ring rolling machine completed its first hot-piece commissioning at Yilait Co., Ltd. in Zhangqiu District, Jinan. The debugging process lasted two days, and the two prototype wide components, each with an outer diameter of 6 meters and a weight of 35 tons, were successfully manufactured in one go. The surface of these components was smooth and even, and all the specified parameters were met with precision. The next month. The equipment will continue with stepped trials for target outer diameters of 10 meters, 12 meters, and 16 meters, as well as trials for thick-walled cylinder components with a maximum height of 3 meters. At present, the largest ring forging manufactured using the radial axial rolling technique has an outer diameter of 10 meters; this record is expected to be broken multiple times by Elyte Co., Ltd. soon, possibly around Labor Day.
The super ring rolling machine was introduced by Elett Group; it is capable of rolling various large-scale disc, ring, and cylinder-shaped forgings with a diameter of 16 meters, a height of 3 meters, and a weight of up to 200 tons. Its radial rolling force is 2500 tons, while its axial rolling force is 1250 tons – making it the largest radial-axial ring and cylinder rolling machine in the world today. This equipment, together with large-scale machines such as a 13,500-ton press, a shaft-type heat treatment furnace with an inner diameter of 17.5 meters, a quenching tank with a diameter of 19 meters and a depth of 5 meters, and a vertical CNC lathe with a diameter of 16 meters, forms part of Elet Corporation’s project for manufacturing large forgings made from high-alloy and non-ferrous metals. It involves collaborative research and development with the team led by Academician Li Yiyi from the Institute of Metal Research, which is one of China’s top metal research institutions. This project is a typical example of the ‘Made in China 2025’ initiative aimed at strengthening China’s industrial foundation, and it plays a crucial role in supporting the research, development, and production of nuclear power systems, advanced petrochemical facilities, heavy manned space missions, very large offshore wind turbines, and large-scale integrated equipment in China’s future.
