A few days ago, leaders of CLP Heavy-Duty Gas Turbine Co., Ltd., made a special trip to Shougang Beiye Company and gave full recognition to the new breakthroughs made by the company in actively participating in the development of major special materials for aero-engines and heavy-duty gas turbines, hoping that the two sides would further strengthen their cooperation and build great power heavy-duty equipment.

Aero-engine and heavy-duty gas turbine represent the overall level of a country’s manufacturing industry, which are an important symbol of the world’s recognized manufacturing power. They are the great power heavy-duty equipment for the key breakthroughs and development of “Made in China 2025”, which are listed as the first of the 100 key tasks to be implemented in the “13th Five-Year” development plan of China. Since the launch of the “aero-engine & gas turbine” major special project, Shougang Beiye Company, as an important research and production base of special materials in China, has actively participated in the basic research, the development of important materials, the construction of industrial systems, and so on.

“It is the honor and responsibility of Beiye to undertake the research and development of the country’s major national special project and to participate in building the great power heavy-duty equipment. The country needs Beiye’s objective of the struggle,” Jiang Xiangdong, Party Secretary and Chairman of Shougang Beiye Company said, “in order to meet the requirements of the core materials of “aero-engine & gas turbine” major special project for the design and manufacture of advanced technological equipment, we have invested in the transformation of the smelting production line and built a new vacuum smelting furnace with a capacity of 3 tons, and at the same time, we have set up a high-tech talent team composed of various professions and posts, so as to do a series of researches from the investigation of materials, design to the experiment”.

Aero-engine is known as the “pearl on the crown” of the modern industry, and gas turbine is a new generation power device after steam turbine and internal combustion engine, which is mainly used in many fields such as electric power, ship and manufacturing. Only a few countries in the world can develop independently aero-engine and gas turbine because of their extremely complex material manufacturing process. “Without reference material, pressing time is the biggest difficulty encountered in the R & D process.” Li Zhenrui, Director of the Materials Research Institute of Beiye Company, said, “the development of core materials of “aero-engine & gas turbine” must be based on a large amount of empirical data. Due to the tight blockade of foreign technology, we could only explore by ourselves and constantly do experiments to obtain data. The research team sometimes ate and lived in the office for a week, working day and night, experimenting over and over again for a piece of data”. It is with a high sense of urgency, responsibility and mission that they persevered in their research and obtained data and results. At present, Shougang Beiye Company has successfully developed special materials such as casting high-temperature master alloy, deformed high-temperature alloy, high-temperature brush wire seal and high-end welding, which can be used in the manufacture of aero-engine power components and control systems. At the same time, in the project research on the first batch of materials for heavy-duty gas turbine blade, the company has successfully developed high-temperature and corrosion-resistant cobalt-based high-temperature master alloy and nickel-based high-temperature master alloy sample materials with a long service life.

Shu Guogang, President and Party Secretary of CLP Heavy-Duty Gas Turbine Co., Ltd., said during his survey research that he hoped to further strengthen cooperation with Shougang Beiye Company, so as to give full play to its advantages in research and production of special materials such as casting high-temperature master alloy, deformed high-temperature master alloy and other special materials to support the localization of heavy-duty gas turbines in China.
