摘要

以Nd∶YAG连续激光为热源,激光扫描加热铸轧辊套材料32Cr3Mo1V表面,接触冷却样品背面,进行了热疲劳性能测试。用集总参数法测量了不同表面粗糙度和氧化状态下材料的激光吸收率,并数值计算模拟了样品表面的温度循环和压应力状态。结果显示,热循环1000周次后,在样品表面烧蚀坑和粗大磨痕处均出现裂纹。1000~2000周次热循环范围内,裂纹长度与热循环次数呈线性关系。由于测试中忽略了铝铸轧过程中辊套承受的机械应力和铝液对辊套的作用,测得的辊套裂纹扩展速率为实际值的一半。

Abstract

By using Nd∶YAG continuous laser as the heat resource to scan and heat the surface of the casting roller sleeve material 32Cr3Mo1V, the thermal fatigue performance is tested by contact cooling the back of the sample. The laser absorptivity of the sample with different surface roughness and oxidation state is measured with the lumped parametric method. The temperature cycle and compressive stress condition of the sample surface are simulated by numerical calculation. The results show that, after 1000 thermal cycles, cracks appear in the ablation hole and at positions with rough scratches on the sample surface. When the thermal cycle ranges from 1000 to 2000, the length of the crack is linearly related to the number of thermal cycles. Because the proposed method ignores the effects of mechanical stress and aluminum liquid on the roller sleeve, the growth rate of the crack length obtained from the test is only half of the actual one.
