On August 28th, the first joint inspection of 11S90ME-C9.2 crankshaft developed by Dalian Heavy Industry was successfully completed by the Lloyd's Register of Shipping, South Korea's STX Heavy Industries, and the shipowner ZODAIC. This is Dalian Heavy Industry's focus on high-end products and intelligence, based on independent innovation, vigorously transforming the economic development mode, and accelerating the product structure adjustment. It is the successful production of the first domestic Mann series 90 crankshaft and Wärtsilä. After the series of 82T crankshafts, another major breakthrough in the development of marine crankshafts above the super-large class has filled the domestic gap, marking that Dalian Heavy Industry has fully mastered the technology of the highest-end manufacturing of large-scale marine crankshafts.
It is reported that the total length of the crankshaft is 21.56 meters and weighs 426 tons. It is the first large-scale butt-type crankshaft in China. It only has more than 1,700 data detected. The precision is demanding and the manufacturing process is very complicated. It represents the latest technology in the world. Level. The biggest technical difficulty of the crankshaft lies in five technologies, such as overall machining of the crankshaft, sectional crankshaft docking, butt-to-crank ground leveling, large-diameter butt flange hole with the same hinge and ground detection. These technologies are all in Dalian Heavy Industry. The first domestic research and development application. Among them, 2 technologies are applying for national patents, and 1 technology will form industry standards.
It is understood that in recent years, Dalian Heavy Industry has made great efforts to strengthen the high-end core technology of crankshaft manufacturing by adhering to the combination of independent innovation and introduction of innovation. Now it has accumulated more than 200 types of crankshafts of various types, and its manufacturing capability covers Mann. Series 50 and above, Wärtsilä series 58T and above, has realized the serialization and mass production of large and above crankshafts with international leading level. The product quality has been highly recognized by users, and the market share has been increasing year by year, becoming world-class. Crankshaft development base.
The successfully-launched 11S90ME-C 9.2 crankshaft will be installed in the 16000 TEU container ship low-speed diesel engine of Zodiac, UK. The diesel engine used by the ship reduces engine emissions by reducing the engine speed, significantly reducing the content of sulfur oxides, nitrogen oxides and carbon dioxide in the combustion products of the engine, meeting the requirements of the International Maritime Organization Tier II emission standards, and achieving energy conservation and environmental protection. With a total length of 21.56 meters and a weight of 426 tons, this crankshaft is the first extra large butt-type crankshaft in China, representing the latest technological level in the world.
It is understood that the same type of crankshaft can be produced in the world. Currently, there are only three companies in Korea and Japan. Dalian Heavy Industry is the fourth company in the world and the first company in China to develop this type of crankshaft. The successful production of the extra-large butt-type crankshaft provides support for the core components of China's super-large vessels. It is very important to promote China's progress from a shipbuilding power to a shipbuilding power and further enhance the overall level and international competitiveness of China's shipbuilding industry. The meaning.
