Dalian Heavy Industry develops large crankshaft products to fill domestic gaps

The crankshaft, as the "heart" of the ship, and the important moving parts of the marine diesel engine, has always been the top priority of the heavy industry research. A few days ago, Dalian Heavy Industry successfully developed several large-scale crankshaft products that filled the domestic gap through independent research and development and technological breakthroughs.
Since the beginning of this year, the international shipbuilding market has recovered, and Dalian Heavy Industry has achieved breakthroughs in a number of large-scale marine crankshaft crankshaft technologies and has broken Japanese and Korean monopolies in this area. Its only mastered "drilling method" manufacturing technology has broken Japan's monopoly; the only mastery of large butt jointed crankshaft manufacturing technology and ultra-long stroke crankshaft manufacturing technology has broken the monopoly of Japan and South Korea; the company's production of large butt joint type marine crankshaft exports to South Korea It broke the record of "Zero Export" for marine crankshafts in China, and it is the only enterprise in China that maintains export of products. Dalian Heavy Industry expects that this year, the production of crankshafts will reach 100, and will reach more than 100 in the next year. It is expected that more than 10 crankshafts with a single weight of more than 200 tons will be delivered.
