Abstract
本发明公开了一种射频超导腔用高纯铌铸锭的制备方法，该方法为：对铌板条进行3～7次真空电子束熔炼，得到高纯铌铸锭；所述真空电子束熔炼的比电能为8度/kg～12度/kg，真空度不大于5×10-3Pa。本发明设计合理、方法简单、操作简便，能有效解决传统铌铸锭生产工艺所存在的实际问题，达到稳定化、批量化生产射频超导腔用高纯铌铸锭的要求，采用3～7次真空电子束熔炼，通过控制比电能，制备的铌铸锭的RRR值和成分均符合射频超导腔用高纯铌铸锭的要求。
English (machine translation): The invention discloses a preparation method of a high-purity niobium ingot casting for a radio frequency superconducting cavity. The preparation method comprises performing vacuum electronic torch melting on a niobium batten for 3-7 times, thereby obtaining the high-purity niobium ingot casting; the specific electric energy of the vacuum electronic torch melting is 8-12 degrees per kilometer, and the vacuum degree of the vacuum electronic torch melting is not greater than 5*10<-3>Pa.…
