Copper melting furnace, graphite crucible or iron crucible, which one is better?

Of course the graphite crucible is good! You can contact Luoyang Songdao Induction Heating Technology Co., Ltd., another factory specializes in the production of graphite crucibles

Nowadays, many copper casting companies are using refractory linings made of rammed refractory materials, which are resistant to high temperatures and have a long service life. The “500KG intermediate frequency copper melting electric furnace” has a service life of about 300 to 400 furnaces.
