摘要: 研究了实际冷却条件下伯格霍德曲线的绘制方法,以及基于伯格霍德曲线的选材方法。通过实际淬火试验,结合材料的实际淬透性曲线,得到了实际冷却条件下的伯格霍德曲线,从而计算得出副箱主轴3R/4处冷速相同对应的端淬点为J25 mm。实际生产结果表明,使用该方法得到的伯格霍德曲线并运用该曲线进行选材是可靠的、科学的。

关键词: 伯格霍德曲线, 淬火, 冷却

Abstract: Drawing method of Bergerhord curve under the actual cooling condition and the material selection method based on Bergerhord curve were studied. After quenching test, the Bergerhord curve under the actual cooling condition is obtained by combing the hardenability curve of the material, based on which the end quenching point at 3R/4 of the deputy box spindle with the same cooling rate is calculated as J25 mm. The actual production results show that the Bergerhord curve obtained by this method is reliable and scientific for material selection.

Key words: Bergerhord curve, quenching, cooling
