This machine adopts the medium frequency induction heating method for melting, which can quickly heat precious metals. At the same time, it has the function of electromagnetic stirring for metals in heating engineering, and can obtain a highly uniform metal liquid with high temperature and composition. This machine is easy to operate, easy to maintain, reliable in quality, and safe in production. It can be used to mix gold alloys and also for gold scrap materials. It not only changes the strong noise and danger generated during the current artificial gas melting of gold, but also causes significant splashing and loss of gold. At the same time, medium frequency electromagnetic waves will not cause any harm to the human body
