摘 要：According to ASTM Designation DXXXX Standard Test Method for Determination of Cooling Characteristics of Quenchants by Cooling Curve Analysis with Agitation (Drayton Unit), a test unit was designed using which the cooling characteristics of a quenchant at different flow rates and different temperatures can be determined. We discussed the effects of flow rate and temperature on cooling characteristics of fast speed quenching oil. The results show that this unit can be well used for determining cooling characteristics of quechants at different flow rates and different temperatures. At the same time our investigation can provide a reference to the establishment of a standard for determination of cooling characteristics of quenchants with agitation.
