In a few days, the 32nd large marine crankshaft produced by Shanghai Marine Crankshaft Co., Ltd. will be delivered offline; half a month later, the company will be the first in the second phase of the Shanghai Lingang Heavy Equipment Industrial Zone. Root crankshaft. Large-scale marine crankshafts have been produced in China from scratch and are now in volume production. This year, Shanghai Crankshaft Co., Ltd. plans to complete 50, and after the second phase of the Lingang project, the annual production capacity will reach 240.
"After that, we will launch the third phase of the project, and finally reach the production capacity of one crankshaft a day. By 2015, we can fully meet the needs of the domestic shipbuilding industry." Lu Yachen, vice president of Shanghai Electric Group and chairman of Shanghai Crankshaft Co., Ltd. said.
Just two and a half years ago, China could not produce large-scale marine crankshafts. Lu Yachen remembers a sentence he said on February 25, 2005. On that day, the crankshaft localization project passed the national acceptance. When Lu Yachen was speaking, he said with excitement: "We have finally realized the dream of several generations of China's shipbuilding industry and ended the situation that China's large diesel crankshafts are completely dependent on imports!"
Since the mid-1990s, China's shipbuilding industry has always occupied the third place in the world, but the semi-combined crankshafts of large-scale marine diesel engines are all dependent on imports. In today's world, only a few countries such as Japan, South Korea, the Czech Republic, Spain, and Poland have the ability to manufacture large-scale marine crankshafts, and the market is highly monopolized.
According to the data, from 1978 to 1997, China spent more than 90 million US dollars on imported crankshafts. In recent years, the annual cost of importing crankshafts has reached 40 to 50 million US dollars. However, the high price is not the most difficult problem for China's shipbuilding industry. The biggest problem is that “one axis is hard to findâ€, and the domestic shipbuilding industry has to give up millions of tons of shipbuilding orders. At the same time, "ships, machines and other axes" also led to an extension of the shipbuilding cycle.
In May 2002, Shanghai Electric (Group) Corporation, Hudong Zhonghua Shipbuilding (Group) Co., Ltd., China Shipbuilding Industry Corporation and Shanghai Industrial Investment Corporation were appointed to invest in Shanghai Marine Crankshaft Co., Ltd., and invested 186 million yuan. Scientific research on large marine crankshafts.
At the beginning, everyone also planned to introduce technology or seek partners, but soon, such thoughts were dispelled, because countries such as Japan and South Korea imposed a “blockade†policy on marine crankshaft manufacturing technology. Lu Yachen recalled that the scene at the time was still vivid: "We went to Korea and Japan to visit the factory, and the crankshaft workshops of others were simply not allowed. We wanted to transfer manufacturing technology from the Czech Republic. They offered a price of 96 million yuan. This is more Inspired our determination: we must come up with the Chinese people's own crankshaft!"
In the past 30 years, the country has twice initiated the development of marine crankshafts, but all ended in failure.
"The key to our success in this development is to bring together the strengths of all parties." It took less than three years to build a Shanghai crankshaft by establishing alliances for production, learning, research, and use, and adhering to technological innovation and institutional innovation. The company has overcome a series of difficulties and accumulated a core manufacturing technology for the formation of a number of marine crankshafts with independent intellectual property rights. For example, in the field of thermal processing, in cooperation with enterprises and research institutes such as Shanghai Heavy Machinery Plant and China Shipbuilding Corporation 12 Research Institute, the research on chemical composition and heat treatment optimization of crankshaft high-purity steel and crankshaft bending forging technology were completed.
In January 2005, a 7.5-meter-long, approximately 60-tonne ship crankshaft was rolled off the line at Shanghai Crankshaft Company, achieving China's zero breakthrough in this field. On February 25th, this semi-combined crankshaft of marine diesel engine, which was written into the history of Chinese shipbuilding, was delivered to Hudong Heavy Machinery Co., Ltd. and became the "Chinese heart" of the 10,000-ton ship. At the same time, the localization project for marine semi-combined crankshafts was completed and passed the national acceptance.
“Now, from steelmaking, primary processing, heat treatment, red quilting to final finishing, we have applied for 10 national patents.†Shanghai Crankshaft's products have already entered the country and entered the Korean market, the second largest country in crankshaft production. The 29 crankshaft contracts signed with Korean shipowners last year have been basically delivered, and it is expected to sign another 50 crankshaft export contracts.
"However, we still have a certain gap in terms of production costs and raw material utilization rates compared with foreign countries." Lu Yachen said: "We are further researching and research, and more than 10 topics have been launched.
"After that, we will launch the third phase of the project, and finally reach the production capacity of one crankshaft a day.
