OMZ-Special Steels signed a contract to supply China with a new generation of high-chromium rotors

OMZ-Special Steels, part of OMZ Group, has signed an agreement with the Chinese company Shanghai Electric Power Generation Equipment for the supply of a new generation of high-chromium rotors. The weight of each product — about 18 tons. The term of the order — the second quarter of 2013.

The rotors are designed for the next generation steam turbines operating at supercritical steam parameters (SSKPP) — with a pressure above 300 bar, and steam temperatures 590-650 ° C. These rotors require harvesting of High, quite complex in the production of steel. Chemical composition — about 10% chromium, and molybdenum, tungsten, vanadium, niobium, nickel and other alloying elements. Heat treatment of the rotor forgings produced by special technology developed by OMZ at elevated temperatures in the range of 1070-1100 ° C.

As previously reported, the production of a new generation of rotors for steam turbines operating at supercritical steam parameters have been utilized by specialists of OMZ-Special Steels recently: In August 2011 the company first manufactured and supplied by request of the Chinese company Shanghai Electric two blanks for rotors of high-chromium steel. Preliminary research work on the development of innovative products was carried out by specialists of the Research Center TK OMZ-Izhora, OMZ-Special Steels and NGOs TSNIITMASH since 2005. The successful development of high-technology products has enabled the company OMZ Special Steels to market a new generation of producers of turbines for Russia as well as China, CIS and Europe.
