The quenching process is a key factor in effective heat treatment that affects the quality and mechanical characteristics of treated parts.
Fuji Denshi has conducted innumerable tests and amassed data concerning proper quenching. Let us look at an example of the quenching process by looking at large commercial idlers. After the heating cycle the idler is lowered in into a quench tank.
The submerged work piece is shot with quenching fluid from quench jackets located in the tank. The quench fluid contains no air bubbles and the jackets circulate the fluid within the tank.
This system results in the formation of a uniformly hardened layer and controlled hardening results. This system is called the "Dip, Spray, Quench" method.
Furthermore, the quenching fluidﾕs temperature and flow are all carefully controlled.
