淬火变形超过工艺要求的工件,必须采取校正的方法进行补救,常用的校正方法有淬火趁热校正、回火校正、冷压校正、热点校正和锤击校正等。关于回火校正法虽在生产中早已有应用,但因长期以来对其校正机理了解甚少,因而在生产中尚未能充分发挥其作用。随着近几年对回火校正机理的研究和规律的掌握,使回火校正的方法有了新的进展,从而能达到其他校正方法难以达到的效果。本文简要阐明回火校正的机理和获得最佳校正效果的条 Quenching deformation of the workpiece over the process requirements, we must take corrective measures to remedy the commonly used methods are quenching calorie correction, tempering correction, cold pressure correction, hot-point correction and hammer correction. Although the application of the tempering correction method has long been in production, it has not yet been able to fully play its role in production due to its long history of poor knowledge of its calibration mechanism. With the research on the tempering correction mechanism and the rule of law in recent years, the method of tempering correction has made new progress, which can achieve the effect that other correction methods can not achieve. This article briefly explains the tempering correction mechanism and get the best correction of the article
