为了提高船用轻型高速柴油机构件的寿命和配合新型大马力轻型柴油机的设计工作,1971年六机部召开的<8.15>会议决定,由四○七厂与部十二所等有关单位协作,积极开展新型高强度铸造铝合金的研制工作。几年来,试制小组在各级党组织领导下,在上海交大、南京铁合金厂等兄弟单位协助下,已基本完成了新合金的成份调试、熔炼、热
In order to improve the service life of marine light high-speed diesel engine components and to cooperate with the design work of the new high-horsepower light-duty diesel engine, the <8.15> meeting decided by Liujiu Machinery in 1971 was decided by the cooperation of relevant departments such as No.407 Factory and No.12 Dept. Development of new high-strength cast aluminum alloy. In recent years, under the leadership of party organizations at all levels and under the help of the party organizations such as Shanghai Jiaotong University and Nanjing Ferroalloy Factory, the trial production team has basically completed the commissioning, smelting and heating of the new alloy
