摘要/Abstract

摘要： 为解决一种2Cr13钢异形模锻件淬火回火后批次性表面开裂的问题,从复查工艺过程入手,通过计算机模拟工件淬火过程中表面应力状态变化,观察开裂工件显微组织及裂纹形貌,分析工件淬火开裂原因,并通过热处理试验验证了淬火制度对工件表层组织以及力学性能的影响。结果表明,2Cr13钢异形模锻件淬火后出现表面裂纹与锻件形状、淬火加热方式以及淬火温度有关,可通过增加锻件过渡区余量、采用到温入炉以及较低的淬火加热温度的方式降低淬火开裂风险。采用1000 ℃淬火,到温入炉作为产品优化后的热处理制度。

Abstract: In order to solve the batch surface cracking problem of a 2Cr13 steel special-shaped die forging part after quenching and tempering by analyzing the reasons of cracking from reviewing production process, simulating surface stress change during quenching process and observing the microstructure of the parts and the crack morphology. Meanwhile the influence of quenching method on surface structure and mechanical properties of workpiece was verified by heat treatment tests. The results show that the cracking of 2Cr13 steel special-shaped die forging parts after quenching is related to the shape of the forging part, quenching heating method and quenching temperature. The risk of quenching cracking can be reduced by increasing the excess allowance of forging parts, or applying hot charging and lower quenching heating temperature. Quenching at 1000 ℃ via hot charging is adopted as the optimized heat treatment method of products.

Key words: 2Cr13 steel die forging part, surface crack, stress distribution, surface microstructure, heat treatment method
