摘要： A quench tank includes a reservoir located within a sump tank. Heated steel parts are dropped through a vertical tube in which a quenching liquid is flowing upwardly from the sump tank and into the reservoir under hydrostatic-induced pressure. Turbulent flow of liquid across the surfaces of the steel parts produces a rapid cooling and quenching action. The liquid upflow is produced by a hydrostatic liquid head communicating with the lower end of the tube. The flow rate of the liquid, measured across the transverse cross section of the tube, is relatively constant, such that the quenching action is relatively uniform across a given part and from one part to another part.
