随着炉容量的大型化,作业中,真空感应熔炼炉脱气时间所占比例明显增高,生产效率下降,引起人们的关注。为了缩短脱气时间、提高生产效率,美国AJAX公司开发了熔化过程中使用单相交流电源,脱气时使用多相交流
With the large-scale furnace capacity, operation, the vacuum induction furnace degassing furnace significantly increased the proportion of time, production efficiency decreased, aroused people’s attention. In order to shorten the degassing time, improve production efficiency, the United States AJAX developed a melting process using single-phase AC power, degaussing the use of multi-phase AC
