Over the years the coreless induction furnace has proven itself to be a valuable tool in the metal casting industry.It has shown a superior ability in producing molten metal that is both homogeneous and uniform in temperature.Years ago,large coreless furnaces were supplied with fixed line frequency power sources.These power sources had many drawbacks which forced limitations on the operation of the melting system.Today,solid state medium frequency power supplies have hiven coreless furnace systems a high degree of flexibility and reliability.They have also made these systems easier to operate.Medium frequency power supplies have become accepted as the coreless induction furnace power source of choice throughout the world.Any existing line frequency furnace now in use can take advantage of this technology by being upgraded with a new solid state medium frequency power supply.
