Induction Hardening of Gears pt. 2 – 2

There are three ways to quench gears in spin hardening applications (Ref. 1):
•    Submerge the gear in a quench tank. This technique is particularly applicable for large gears.
•    Quench “in place” using an integrated spray quench. Small- and medium-size gears are usually quenched using this technique.
•    Use a separate, concentric spray-quench block (quench ring) located below the inductor.
