ප්‍රේරක දියවන උදුනක තඹ උණු කිරීම සඳහා යකඩ කූඩුවක් භාවිතා කළ හැකිද?

You can choose graphite crucible for melting copper in induction melting furnace, 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.
