摘要
对核电泵壳用钢Z3CN20-09M的冶炼工艺进行了改进。分别熔炼钢水及合金,合兑后简单微调成分即进行VOD操作。能够保证质量并将冶炼时间大大缩短。
The smelting process of Z3CN20-09M steel used for nuclear electric pump housing has been improved. The steel and alloy have been smelted separately, then after mixing process the composition has been fine adjusted （ that is VOD process）. All this can guarantee the quality and sharply shorten the duration of heating.
