ISM— The Process Induction Skull Melting ISM is a method of melting metals in a segmented, water-cooled copper vessel while under vacuum or controlled atmosphere using an induction coil. This is done metal-to-metal, without a refractory lining. The copper crucible is made up of water-cooled segments or “fingers.” The magnetic field produced by the coil, in effect, passes through the crucible to induce heat in the metal charge causing it to melt. The field also intensely stirs the liquid metal pool in the pattern shown in the diagram. The stirring promotes a very homogeneous melt pool and effectively...

An Inductotherm Croup Company Induction Skull Melting Furnaces Background - Exclusive Licensee of the Patent Holder In 1985, Consarc entered into an agreement with the company that patented the Induction Skull Melting (ISM) process to be the exclusive worldwide licensee to promote the ISM Technology. Since that time Consarc has continuously strived to improve, develop and refine the ISM Technology to increase its efficiency. We developed correlations between materials melted and power levels, frequencies and crucible diameters. Consarc has pioneered new manufacturing techniques for ISM crucibles,...

Advantages of Consarc ISM furnaces This innovative process utilizes a segmented water-cooled copper crucible for refractory-free induction melting. Melting in a water-cooled copper crucible eliminates the possibility of reactions with any refractory, allowing for the melting of reactive metals and alloys that require super-clean melting conditions. Some Features of the Modern Consarc ISM Furnace are: • Robust segmented copper crucible machined from a single forging • Crucible life of tens of thousands of heats • Frequency matched Inductotherm ISM power supplies • Ability to make alloy additions...

SINGLE CHAMBER Excellent for R&D and Prototype Facilities 镕 Centrifugal Casting Low Overhead Clearance Օ Small Footprint Flexible Օ Upgradable to a Tandem Unit Lowest Cost TANDEM CHAMBER Օ Independent Units Sharing a Power Supply Maximum...

Advantages of Casting with ISM The ISM process has some inherent advantages over the Vacuum Arc Skull Casting (VASC) process that has traditionally been used in many titanium and reactive metal casting applications. The biggest advantage is in the flexibility of the charge material that can be used. A cylindrical electrode must be fabricated for use in the VASC furnace. A large amount of effort and expense goes into producing the electrode needed at the beginning of the process. Compacted sponge, other raw material, and alloying elements are compacted and welded together to form the electrode....

An Inductotherm Group Company Inductotherm VIP ISM Power Supply In conjunction with Inductotherm Corporation, the largest manufacturer of induction air and vacuum melting equipment in the world, Consarc has developed a line of solid state power supplies specifically tailored to the particular demands of Induction Skull Melting. These designs are based on the VIP Power-Trak technology that Inductotherm introduced in 1977 and has continually updated and refined over the years. The ISM power supplies maintain all the fine features that VIP Power-Trak users around the world have enjoyed for many...
