　　Which kinds of electric furnaces in industrial electric furnaces are used to cast non-ferrous metals

　　to melt scrap copper, these three common electric furnaces can be used: power frequency electric furnace, resistance furnace and medium frequency electric furnace.

　　the three furnace models are introduced as follows:

　　power frequency electric furnace has relatively simple structure and is suitable for mass casting production. for example, the capacity of a single furnace is between 5-50T, which is more suitable for melting at power frequency.

　　The resistance furnace has the characteristics of simple structure and low equipment procurement cost, but the resistance furnace has low production efficiency and low thermal efficiency. So it is not suitable for the production of cast copper.

　　Intermediate frequency electric furnace has the characteristics of relatively complex electrical structure, high production efficiency and low energy consumption. It is more suitable for the production of copper casting with a single furnace capacity below 5T.
