철 도가니를 사용하여 유도 용해로에서 구리를 녹일 수 있습니까?

You can choose graphite crucible for melting copper in 유도 용해로, or you can buy induction furnace ramming material yourself, and directly ram the furnace wall lining on the furnace wall to directly smelt copper. It is definitely not possible to use an iron crucible.
