collapsible drum coiler

The evaluation of quenching medium characteristies and the influence of operating temperature on the dimension swelling and contracting and deformation were introdced,the effects of quenching medium characteristics and operating temperature during the heat-treatment of bearing parts were showed,so that the evedence was given for selecting quenching medium and reducing finishing allowance of parts.

探讨了淬火介质特性评价及使用温度对套圈的尺寸涨缩及变形的影响,体现了淬火介质特性及使用温度在轴承零件热处理过程中所起的作用,为淬火介质的选用和减少零件的加工留量提供依据。
