为进一步提高钇基重稀土球墨铸铁焊条质量和批量转厂生产,10月20日—31日在福建省建阳县召开了钇基重稀土球墨铸铁电焊条第三次攻关会。会议由钇球铁电焊条研究课题组组长哈尔滨焊接研究所和武汉内燃机厂负责召集。参加单位有山东工学院、建阳焊条厂、冶金部有色院、长春稀土合金厂、吉林工大、潍坊发动机厂、大连造船厂等25个单位、33名代表。会议分两个阶段进行:第一阶段是在建阳焊条厂,确定了钇球铁焊条配方,进行了批量
In order to further improve the yttrium-based heavy rare earth ductile iron electrode quality and batch production plant, October 20 -31 Day held in Jianyang County, Fujian Province yttrium-based heavy rare earth ductile iron welding electrode third meeting. Meeting by the yttrium iron electrode welding research group leader Harbin Welding Institute and Wuhan internal combustion engine factory is responsible for convening. There are 25 units and 33 representatives from Shandong Institute of Technology, Jianyang Electrode Factory, Ministry of Metallurgy, Changchun Rare Earth Alloy Factory, Jilin Industry and Technology University, Weifang Engine Factory and Dalian Shipyard. The meeting was divided into two phases: the first stage is in Jianyang electrode factory, to determine the yttrium iron ball electrode formula, the bulk
