On November 28, 2019, the polar icebreaker steel technology seminar and exhibition jointly organized by the academia sinica of baosteel group and Shanghai maritime university was held at the baosteel complex. Baoshan iron and steel co., LTD., general manager assistant, dean wu jun, academia sinica, baoshan iron and steel co., LTD. Department of thick plate Meng Wenwang, director of the institute, vice minister of thick plate and thick plate jian-hua ding, former party secretary of Shanghai maritime university yong-xing jin, a professor at the Shanghai maritime university institute of Marine science and engineering professor li-hua dong, and polar research center in China, jiangnan shipbuilding group (share) co., LTD., China classification society, China shipping and Marine engineering design and research institute and other polar shipping operations, design, construction, evaluation experts in the field of present.
Wu jun, assistant to the general manager of baoshan iron & steel co., LTD., and President of academia sinica, delivered the opening speech. He pointed out that in recent years, with the exploration and research of the world's maritime powers and powers expanding to the polar regions of the deep sea, the need to build high-tech ships adapted to the extremely cold and ultra-low temperature environment has become increasingly urgent. The research, development and preparation of steel materials for ships and Marine engineering are of great importance in order to ensure ships to carry out operations in polar ice sea area, extremely cold and low temperature environment, deep sea hydrothermal area and high humid and hot sea area of the south China sea. For a long time, the research on the science and technology of material preparation in China has lagged behind, some special materials are imported, and the research and development of Marine extreme environmental equipment is in a gap, which has become a bottleneck restricting the exploration of the deep sea and the research of polar science in China. Therefore, baosteel and Shanghai maritime university aiming at national polar ocean research and the demand of ship and ocean engineering polar waters play their respective advantages, deepen the cooperation between colleges, since 2014, to build "Marine extreme environmental steel material preparation and erosion control joint laboratory", cold high level Marine environment of ship steel mass production technology system research and development, It has successively applied for approval of the "13th five-year plan" national key research and development projects -- extremely cold and ultra-low temperature environment steel for ships and its application, Shanghai special fund project for civil-military integration development -- applied technology research of steel engineering for ships with extreme environment and high safety, and other major projects. In Shanghai university plateau - ship and ocean engineering disciplines construction projects, under the impetus of the sea of materials science and engineering research institute at Shanghai maritime university team has invited customs icebreaker "snow dragon" original planking r&d unit Ukrainian iron and steel research institute of the national academy of sciences related materials metallurgy experts to Shanghai polar Marine high abrasion resistant steel technology exchange and joint experiments, promoted the development of a new type of polar steel development, promoted in extremely cold, deep, extremely hot and humid sea under extreme conditions such as key service performance. With the support of the China polar research center, the polar ship high abrasion resistance steel jointly researched and developed by universities and enterprises has been produced in batches of nearly 1000 tons and successfully applied to the construction of "snow dragon 2" after many shipboard experiments on "snow dragon". Baosteel and maritime university colleges and universities "enterprise +" cooperation in research and development mode, is the successful model of combining theory with practice, give full play to both the colleges and universities, systems, advanced materials research and development and failure mechanism analysis and research ability, and through the enterprise strong implementation and application of the industrialization of the ability to convert scientific research achievements into productivity, realize the win-win purpose.
In his concluding remarks, professor jin yongxing, former party secretary of Shanghai maritime university and head of ship and ocean engineering in Shanghai university, thanked baosteel for its support to the joint laboratory of baosteel and Shanghai maritime university over the years. He pointed out that the design and construction of the polar icebreaker is fully localized, which largely depends on the r&d and production of domestic steel for low-temperature ships. Baosteel and Shanghai maritime university with "the anxious state of urgent, to build national needs" as own duty, not afraid difficulty, go forward, to "build China's own icebreaker" as the goal, adhere to the long-term, finally overcome the friction resistance to low temperature corrosion materials preparation, processing and testing technology and methods such as bottlenecks, research and development to produce performance to achieve even more than abroad with cryogenic vessel steel of the industrialization of the price of steel products, application and the testing result, the ship and ocean engineering for our country the polar waters with domestic steel into a powerful demonstration and guarantee, This is both sides "do not forget the original intention, keep in mind the mission" theme education learning practice results of the vivid embodiment.
Commissioner of polar research center of China ship 53:2479, baosteel group chief researcher Gao Shan academia sinica, jiangnan shipyard (group) co., LTD. "snow dragon 2" total craftsmen zhao, and Shanghai maritime university institute of Marine science and engineering professor xue-ting chang, professor liu tao respectively for the arctic environment and ice-class material requirements, "the polar ship steel development and engineering application research", "" snow dragon 2" polar research icebreaker structure and welding technology ", "the polar platform and ship material failure mechanism research report", "the polar Marine steel welding materials development and evaluation of the research, the theme of the report.
The university-enterprise cooperation organize technical seminars and exhibition, we demonstrate the university-enterprise cooperation research achievements, also use the service to the integration of the polar cold steel, processing and application side, the power of the ship design construction and the standard of third party agencies set up a platform, help together production, promote the polar cold steel development and engineering application of systematic, platform and specialization, further consummates our country low temperature Marine special metal processing from manufacture to application and service the whole process of a complete solution, breakthrough of the polar ice environment vessel materials of "their" dilemma, For vigorously promote the construction of the "silk road" on the ice to clear the material obstacles.
