What is Vacuum Induction Melting

Vacuum induction melting, referred to as VIM, a metallurgical method for generating eddy current heating in a metal conductor by electromagnetic induction under vacuum conditions. The VIM process has a small volume of the melting chamber, a short vacuuming time and a short melting cycle, and is convenient for temperature and pressure control, recyclable volatile elements, and accurate control of alloy composition. Due to the above characteristics, VIM has developed into one of the important processes for the production of special alloys such as special steels, precision alloys, electrothermal alloys, high-temperature alloys and corrosion-resistant alloys.
