由研磨而引起的被加工制品表面层状态的变化以及微观组织的局部变化(所谓研磨烧灼),显著地会降低钢的接触疲劳强度。研磨烧灼产生的原因不仅有可能是加工制度、砂轮质量及钢的牌号,而且有可能是工艺流程的程序,特别是机械加工及热处理的程序。在本文中,曾研究了加工过程进行的程序产生研磨烧灼的影响以及冷轧精轧辊的耐磨性的影响。研究 Changes in the state of the surface layer of the workpiece due to grinding and local changes in the microstructure (so-called abrasive burn) significantly reduce the contact fatigue strength of the steel. The cause of grinding cauterization may not only be the processing system, the quality of the grinding wheel and the grade of the steel, but also the process flow, especially the machining and heat treatment. In this paper, we have studied the impact of the process carried out by the machining process on the burnishing of the mill and on the wear resistance of the cold-rolled finishing rolls. the study
