Induction heating is a popular method of metal heating using a series of conductive coils to induct alternating currents on a working head against its resistivity thus heat. Induction heating equipment is thereby made available to perform a wide range of heating jobs and is known for being reliable, efficient, quick and powerful. However, other variables such as resistivity and the magnetic properties of the substance being heated are also factors that determine the feasibility of your induction heating tasks.
Modern industrial world uses induction heating equipments in manufacturing to treat conductive products, heating and joining them, or as a common device to test certain materials. Because of its relatively low cost in setting up, operation and maintenance, induction heating equipments have played a major part in the creation of almost everything we come into contact with in our daily lives.
Induction heating machines work through Electromagnetism. High frequency bursts of electricity fire an alternating current through the main coil of the induction heater – this coil is usually made of copper – it is because of these rapidly alternating currents that heat is produced and built up in the coil. As a result of Electromagnetism, negative high frequency alternating currents are caused in the conductive item that is to be heated, generating enormous heat because of resistivity. The level of heating achieved depends on the size of the coil and the charge of the currents that are alternating, along with the physical qualities of the item in question, such as the amount of friction that will be created as a result of natural resistivity, as this creates friction, which in turn generates extra heat.
Induction heating equipment can reach temperatures as high as 2000 degrees in less than a second, it’s clean, fast and much more useful than any other approaches. No wonder why induction heating is so popular and in such high demand across a whole range of industries.
