OREANDA-NEWS. July 23, 2012. The very first pre-stressed steel wire-wound multicored forging production line (40MN) was successfully put into commissioning in the Precision Forging Industry Base of the 22nd China Metallurgical Construction Group (22MCC Group), reported the press-centre of 22MCC Group.  

This line is designed with the most advanced technologies of the world, filling the blank space of China in this field.

According to the Restructuring & Revitalization Planning of Equipment Manufacturing Industry of China, the large-sized die forgings and the heavy equipment are not only the key products attached with essential support, but also the most scarce matching products and technical equipment in our country. In 2010, MCC Group, 22MCC Group, Tsinghua University and Yanshan University started collaboration and took the first to launch the hydraulic press with large tonnage, high pressure and high flow rate by means of pre-stressed steel wire-wound technology. On this basis, the first set of multicored forging press (40MN) was finally invited. In the meantime, quite a few technical problems were resolved and the first precision die forgings were produced. As a matter of fact, the multicored forging has opened a new era for production of large-sized forging equipment on a worldwide advanced level in China.

The Precision Forging Industry Base of 22MCC Group, which is located in the High-tech Zone of Tangshan City, is mainly engaged in the manufacturing of multicored die forgings and heavy equipment (including precision forgings for valves with large diameter, high temperature and high pressure; oil wellhead forgings; and die-forging hydraulic press).

The completion and commissioning of the base marks that 22MCC Group has stepped onto a new height in terms of equipment manufacturing business. This will make a new chapter in the history of die-forging equipment production in China, and give a great push on Chinese valve industry for technical advancement and upgrading.
