Abstract

This work aims to study the effect of roller hardness on the surface quality of AISI 1211 burnished steel surfaces. High-speed-steel rollers with untreated and cryogenic treated conditions are employed for roller burnishing. Cryogenic treatment is carried out at the temperature of −180°C for 36 hours in a liquid nitrogen bath followed by tempering at 200°C for six hours. CNC turning centre is employed for roller burnishing. The surface quality is measured in terms of surface roughness and hardness against the function of three different turning parameters namely spindle speed, feed rate and depth of penetration. The average hardness of cryogenic treated rollers is increased from 380 Hv0.5 to 625 Hv0.5. The results revealed that increasing the spindle speed significantly affected the surface finish and increase in roller penetration depth increases the hardness of AISI 1211 steel surfaces. Cryogenic treated rollers provide better surface finish and hardness on the AISI 1211 steel samples than untreated rollers.

研究了轧辊硬度对抛光后AISI 1211钢表面性能的影响

本工作旨在研究辊硬度对AISI 1211抛光钢表面质量的影响。采用具有未处理和深冷处理条件的高速钢辊进行辊抛光。在−180°C的温度下，在液氮浴中进行36小时的低温处理，然后在200°C下回火6小时。轧辊抛光采用数控车削中心。表面质量是根据表面粗糙度和硬度来测量的，与三个不同车削参数（即主轴速度、进给速度和穿透深度）的函数相对应。深冷处理辊的平均硬度从380Hv0.5增加到625Hv0.5。结果表明，提高主轴转速会显著影响表面光洁度，而增加轧辊穿透深度会增加AISI 1211钢表面的硬度。与未经处理的轧辊相比，经过低温处理的轧辊在AISI 1211钢样品上提供了更好的表面光洁度和硬度。
