引言欲要提高轧机的能力,就得要增大其工作辊所能承受的负荷,因而也就需要改进轧辊的质量。在一些现代的轧机中,功率和速度都同时增大,剥落现象往往令人可怕。所以对于导致剥落过程之研究有巨大意义,许多同行亦都深表关切。在本研究中,我们试图将支配轧辊剥落的机理综合一下,将一些对它有影响的各参数作一比较精确的阐明。我们已详细地测定了一根感应淬火的冷轧工作辊的工作应力,以及对剥 Introduction To improve the mill’s ability to increase the load on its work rolls, there is a need to improve the quality of the rolls. In some modern mills, both power and speed increase at the same time, and spalling is often terrible. Therefore, there is great significance in the research leading to the spalling process and many colleagues are also deeply concerned. In this study, we tried to synthesize the mechanism governing the spalling of the rolls and give a more precise explanation of some of the parameters that affect it. We have measured in detail the working stress of an induction hardened cold work roll,
