... speeds and output power may need to be changed as the part moves from the larger diameter to the smaller diameter. Finally, there is substantial application of horizontal scanners to full-length induction hardening of full-length bars and for ball screws. Fig. 10.18 Shaft with changes in diameter...

... and current regulation tend to the output power better when there are wide variations in impedance during the heating cycle, such as when a scanner passes over different diameters of a workpiece when heating. Regulation of the power supply is important so that the total power produced into the workpiece...

..., individual workpieces are placed on a loading vee by a hydraulic pusher, magazine, or other means. A second device then loads the billet or bar onto the walking beam, where it is “walked” through the line by a series of lifting, horizontal transfer, and lowering motions into consecutive vees in the guidance...

... are designed to locate horizontally on the workpiece so that current is induced in the longitudinal direction. Round workpieces are rotated at high speed so that a case can be produced around the diameter. Coils for single-shot heating generally require characterization and usually have flux concentrators...

... more system versatility. The mass of a workpiece is used to self-quench the part ( Fig. 6.10g ). A 4340 steel will quench very effectively in some applications using this technique. Workpieces are pushed horizontally through an induction coil, dropping into a quench tank to be brought out...

... that is faster than the test loop. The data is smeared in the horizontal scan direction, and the background is averaged into the LADA site data reducing its contrast. In [7] , the authors demonstrated a method of resolving the time of a LADA interaction by measuring the shift of the LADA site when...

.... The simpler of the two employs a simple single-turn or multiturn coil with a separate quench ring which can be mounted on the scanner ( Fig. 8.29a ). For larger production runs, on the other hand, a double-chamber coil which incorporates both coil cooling and quenching capabilities is often the preferred...
