COMPLETE EQUIPMENT FOR INDUCTION HEATING

Hardening Induction Equipment

Induction heating technology is particularily advantageous for spot and surface hardening parts comprised of hardenable materials, because it is possible to attain a high specific power output of many kW per cm2 of surface area of the heated piece, and this takes advantage of what is called the "skin effect." The higher the frequency of oscillation of the inducted current, the less penetration there is in the heated layers of the working piece. For hardening depths of many millimeters, frequency oscillation of up to 10 kHz is chosen, while for depths in the 10th's of a millimeter, kHz in the hundreds are used.

Fast heating is following by quick cooling, the best method being a cooling spray. The result is a hardened surface and a strong core of the processed piece.

The hardening system typically incorporates a frequency converter with its associated equipment, a frequency transformer, the heater for gradual or one-time hardening, and a cooling water supply.

For solving challenges related to hardening in the scope of mid-frequency, ROBOTERM Chotebor partners with companies like Martenzit, who are industry specialists in applying induction technology to hardening. In applicable situations, we share in the construction of hardening equipment by supplying frequency converters and additional compentents of the hardening system.
