Dapatkah wadah besi digunakan untuk melelehkan tembaga dalam tungku peleburan induksi?

You can choose graphite crucible for melting copper in tungku peleburan induksi, 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.
