8月28日,我国自行设计、制造的第一只大型集装箱船用螺旋桨在大连船用推进器厂交工,从而改写了以往我国集装箱船用螺旋桨只能依赖进口的历史。该螺旋桨将安装在上海船厂为德国船东建造的3500箱集装箱船上。该5叶桨直径7.75米,成品重量44.34吨,生产过程中采用了国际先进水平的双炉体中频感应电炉进行铜合金熔炼,使用了国外引进的五轴联动数控铣床进行桨叶面加工,产品的质量和加工精度都达到了国际先进水平。目前,渤船重工、上海外高桥造船公司、沪东中华造船(集团)公司等国内大船厂分别与大连船用推进器厂签订了
August 28, China’s own design and manufacture of the first large-scale container ship propeller Delivered at Dalian Marine Propulsion Plant, thus rewriting the past, China’s container ship propeller can only rely on the history of imports. The propeller will be installed on 3,500 container vessels built by Shanghai Shipyard for German owners. The 5-blade diameter of 7.75 meters, the finished product weight 44.34 tons, the production process using the international advanced level of two-furnace induction furnace for copper alloy melting, the use of imported five-axis CNC milling machine blade surface processing, product The quality and processing precision have reached the international advanced level. At present, Bohai Shipbuilding Heavy Industries, Shanghai Waigaoqiao Shipbuilding Company, Hudong Zhonghua Shipbuilding (Group) Company and other domestic shipyards and Dalian Marine Propulsion Plant signed
