Abstract
An intensive quenching (IQ) apparatus and method of quenching heated parts is provided. The IQ apparatus includes a chute for placing parts into a tank including liquid quenchant. The parts fall through the quenchant in the chute and are received by a conveyor belt. The parts are then transported on the conveyor through an inner channel of a conduit. An agitation rate of the quenchant in the inner channel is increased by an agitator.
Claims6
A method for intensively quenching heated parts, the method comprising:
- delivering the parts into a quenchant contained in a tank via a chute;
- receiving the parts from the chute on a conveyor, wherein a portion of the · conveyor is located within an internal passage, with a constant cross-sectional area, of a conduit and encircled by the conduit;
- providing a constant quenchant flow velocity in the internal passage using an agitator, wherein the agitator causes the quenchant flow velocity in the internal passage of the conduit to be greater than a quenchant flow velocity outside the conduit;
- and transporting the received parts towards an exit from the quenchant using the conveyor.
