[0002] The vacuum melting furnace mainly uses medium frequency power supply for induction heating to achieve the melting and temperature raising of the corresponding metal materials. When adding materials to the traditional vacuum melting furnace, fine materials can easily splash directly to the outside of the furnace, resulting in unnecessary losses.

[0003] The existing authorized patent CN216845651U discloses a vacuum melting furnace for processing low-silver lead-free solder alloys. The barrier bracket and anti-wear roller can block the splashing fine materials during the feeding process of the melting furnace, thereby avoiding unnecessary losses caused by material splashing.
