Identification of Heat Transfer Coefficients by Use Conditions of Quenching Oil Katsumi ICHITANI1 (1.Lubricants Research Laboratory, Idemitsu Kosan Co., Ltd., Chiba, Japan) 摘要:Heat transfer coefficients of the quench medium are necessary for heat-treatment simulation. Cooling characteristics of quenching oil vary with kinds and usage greatly. Users are selecting oil solutions that come up......
Gas Quenching Small Components Paul Stratton1 (1.BOC, Sheffield, UK) 摘要:Gas quenching is an environmentally friendly and effective way of quenching components. However it has not been possible to apply it to small components because of the difficulties of jigging. A method of gas quenching such small components is described in which they are levitated in a confined gas stream. The method......
