为了提高球铁曲轴的内在质量,解决用地方铁生产曲轴的技术难关。一机部下达计划,由永康拖拉机厂、省机械科学研究所负责,上海内燃机研究所,上海冶金研究所参加的S195型柴油机铁型复砂“杭钢”球铁曲轴的攻关项目,经过四年多的大量试验和深入研究,并在简易生产线上经历了三个月的批量试生产,证明采用铁型复砂新工艺,可大大提高曲轴的性能和质量。省机械局受农机部委托,于去年十二月十七日至二十日召开了鉴定会议。与会代表经过现场复测和技术交流,一致认为这项科
In order to improve the intrinsic quality of the ductile iron crankshaft, the technical difficulties in producing the crankshaft using local iron are solved. The First Ministry issued a plan, and the Yongkang Tractor Factory and the Provincial Institute of Mechanical Science were responsible for the research project of the Shanghai Iron and Steel Institute and the Shanghai Metallurgical Research Institute for the S195 diesel engine iron-sandesite “Hanggang” ball iron crankshaft. Extensive trials and in-depth studies, and three months of trial production on a simple production line, proved that the new iron-based resurfacing process can greatly improve the performance and quality of the crankshaft. The Provincial Machinery Bureau, commissioned by the Ministry of Agricultural Machinery, held an appraisal meeting from December 17 to December 20 last year. The participants met the site retesting and technical exchanges and agreed that this section
