KSO 250/8-A30 Compact Mid-frequency Heater (reconstruction)

The heater was reconstruction for the Ostroj Opava Group and is designed for the induction heating of cross-sectionally round steel billets up to forging temperatures.  During its reconstruction, pneumatic, cooling and electrical components were all completely upgraded.  A reconstruction stepping conveyor allows a consistent feed of stock to the pneumatic feed piston. The temperature of each heated piece is measured with a non-contact pyrometer and the time/date stamp and temperature value can be saved to the PLC memory.  The reason for the reconstruction was to eliminate a problem of billets sticking to each other at the inductor exit.  The pneumatic jaw extractor was replaced with a roller extractor, which helps guide the billets leaving the inductor in such a manner that that billet exit angle doesn't change until the entire billet is clear of the inductor core.  Due to this change,  all the inductor ports were changed. Simultaneously, the hot billet sorter was changed for a slightly different model that allows for the installation of a billet separator, which functions to separate billets which are occasionally stuck to each other as they leave the inductor.   It could be said that the billet separator is capable of separating billets stuck to each other that would normally break apart if dropped to the floor from a height of .5 meters.  From the center chute of the hot billet sorter, properly heated pieces fall and continue on to the press window.
