摘要
为保证导轨尺寸的稳定性,淬火后在-70℃进行冷处理,使残余奥氏体完全转变。介绍了GCr15镶钢导轨热矫直工艺:于180℃矫直至+0·30mm,低于50℃矫直至+0·10^+0·15mm;室温下矫直至+0·08^+0·10mm。
To ensure the stability of guideways, cool treatment should be done under the temperature of -70℃ to convert the remaining austenite after quenching. This article introduces the techniques of heat rectifying of guideways with inlaid GCr15 ： rectified to ＋0.30mm in 180℃ ; rectified to ＋0.10mm below 50℃ ; rectified to ＋0.08 - ＋0.10mm in room temperature.
