On May 12, the delivery ceremony of China’s first large-scale marine crankshaft forging with a bore of 920 cylinders was held. Shanghai Electric Group’s Shanghai Heavy Casting and Forging Co., Ltd. obtained the WinGD patent certification for two-stroke engine crankshaft forgings with a bore of 96cm and below. Shanghai Marine Crankshaft Co., Ltd. delivered the first set of domestic X92 large-scale marine low-speed engine crankshaft forgings.
Sheng Jigang, member of the party group of China State Shipbuilding Corporation, deputy general manager, and Jin Xiaolong, member of the party committee and vice president of Shanghai Electric Group, attended the ceremony and had talks and exchanges. Persons in charge of CSSC headquarters and relevant member units, and Shanghai Electric Group headquarters and relevant member units attended the ceremony.
As a key resource for marine engines, crankshafts are crucial to the safety of China’s shipbuilding industry chain and supply chain. The domestic large-scale marine low-speed engine crankshaft forging obtained patent certification and the delivery of the first set of forgings is a symbolic achievement of China State Shipbuilding Corporation and Shanghai Electric Group to realize the power of shipbuilding, and it is a symbol of China State Shipbuilding Corporation and Shanghai Electric Group giving full play to their advantages in industry, technology and resources. In the field of ship power and high-end equipment manufacturing, it is a model of strong alliances and deepened cooperation, laying a solid foundation for building a safe, independent and controllable industrial chain and supply chain for ship power, enhancing international competitiveness, and promoting high-quality development of both parties.
Large-scale castings and forgings are key basic components necessary for a country’s major technical equipment and major engineering construction. Its manufacturing capacity and level directly determine the manufacturing capacity and overall level of a country’s equipment industry.
SHC is a well-known large-scale casting and forging manufacturing base in my country. It undertakes the important task of researching key products and technologies such as thermal power generation equipment, pulverizing equipment, metallurgical steel rolling machinery, forging equipment, marine crankshafts, nuclear power main equipment and other large-scale casting and forging. , continue to fill the gaps for the needs of China’s power stations, metallurgy, forging, navigation and other industries, provide high-quality large-scale castings and forgings for heavy equipment, and create “China’s first” and “world’s first” one after another.
Large-scale marine crankshaft forgings are another key product of SCR. Large-scale marine crankshaft forgings are the core components of high-power low-speed diesel engines. Because of their high precision manufacturing technology, demanding performance requirements, and complex processes, whether they can be independently developed represents the level of the national shipbuilding industry. In 2005, Shangzhong Factory successfully manufactured the first large-scale marine crankshaft, which changed the history of my country’s dependence on imports of marine crankshafts, and also reversed the situation of “the ship waits for the machine, and the machine waits for the shaft” in the shipbuilding industry. In addition, Shanghai Heavy Casting and Forging also produced container ship rudders exported to Denmark and the world’s largest marine hook.
