On Nov. 27, Sinomach-erzhong conquers F Grade, a major forgings on heavy duty gas turbine turns daughter forging manufacturing bottleneck, boost domestic first self-developed F 50 mw heavy duty gas turbine in dongfang turbine co., LTD., dongfang electric group gas turbine engine lab smooth realizaTion running at full capacity, unit run successfully using the key materials and core forgings are independently developed by the company and supplier.

Since the day of independent research and development of f-class 50MW heavy gas turbine, Sinomach-erzhong has carried out a lot of basic research work. Especially in sichuan province key core technology to increase support to strategic emerging industries, the company actively declare the heavy duty gas turbine rotor forgings research on key technology of manufacturing project, take the lead in offering east steam for 4 sets of F 50 MW heavy gas compressor rotor forgings and a full set of turbine wheel forging, make the company become the first in the domestic manufacturing heavy duty gas turbine rotor forgings.

After the development of rotor forgings for f-class 50MW heavy gas turbine, the company has successfully developed a complete set of rotor forgings for 300MW F-class heavy gas turbine compressor and turbine, and formed mass production capacity. According to the expert group's appraisal, the product technology and quality have reached the domestic leading and world advanced level, filling the domestic gap, and the product can completely replace the import, achieving a major breakthrough in the manufacturing field of the key large components of heavy gas turbine in China, and making a positive contribution to the sustainable and high-quality development of China's energy industry
