Process Description. A VIM furnace is simply a melting crucible inside a steel shell that is connected to a high- speed vacuum system (Fig. 1). The heart of the furnace is the crucible (Fig. 2) with heat- ing and cooling coils and refractory lining. Heating is done by electric current that passes through a set of induction coils.
The amount of inductive stirring in any given furnace can be manipulated for special applications if required. Induction Vacuum Melting. Because induction heating is accomplished using a magnetic field, the work piece (or load) can be physically isolated from the induction coil by refractory or some other non-conducting
Vacuum Induction Melting furnace offered features precision design & construction finish and finds use in meeting the processing of stainless steel, super alloys, specialty steels and other alloys. Made available in light weight finish, these provide for high speed operations while allowing for simple and convenient operation

For many modern manufacturing processes, induction heating offers an attractive combination of speed, consistency and control. The basic principles of During World War II, the technology developed rapidly to meet urgent wartime requirements for a fast, reliable process to harden metal engine parts. More recently, the
Operating frequencies range from utility frequency (50 or 60 Hz) to 400 kHz or higher, usually depending on the material being melted, the capacity (volume) of the furnace and the melting speed required. Generally, the smaller the volume of the melts, the higher the frequency of the furnace used; this is due to the skin depth
Electrode VIM Furnaces. Electrode VIM systems are the largest VIM systems with heat sizes ranging from 5 Master Alloy VIM Furnaces. Master Alloy VIM systems are characterized by their ability to pour many multipl Small / R&D VIM Furnaces. Smaller VIM furnaces are commonly used to start a company or for research
Since the first unit was produced in 1957, ULVAC has delivered over 200 vacuum induction melting furnaces to customers in Japan and around the world. They have been used in developing new technologies such as high-vacuum degassing and refining using cryopanels, and multi-element alloys created by

Resistance leads to the Joule heating of the charge metal. Operating frequencies of an alternating current depend on the material being melted, the capacity of the furnace and the melting speed required. Due to the skin-effect, higher frequency is used for the smaller volume of the melts. Lower frequencies can generate
