摘要：

In order to analyze the factors affecting attenuation of the surface roughness of textured work rolls, find out the primary and secondary order of each factor, explore the attenuation process of surface topography of typical textured rolls and obtain the mathematical model which can be applied to the production site, a series of experiments specific to 9Cr2Mo work rolls and Q345 strips were carried out to simulate cold rolling process under the conditions of different initial roughness, different pressure, different lubricating liquid concentration and different rolling mileage. The results show that: within the test level, the initial roughness, test mileage and rolling force are highly significant for the attenuation process of roughness, while the lubricating oil concentration has no significant effect. Among these factors, the most important influencing factor is the initial roughness, the rolling mileage is followed by, and then is the rolling force. In terms of the mathematical description of the attenuation process, the attenuation of the roughness of roll surface has a linear relationship with initial roughness and test force, while it has a exponential relationship with the rolling mileage. Based on the experiment, the mathematical model of the attenuation process of the surface roughness of textured work rolls during cold rolling is established, and the feasibility and reliability of the model is confirmed by comparing with field data. © 2018 Journal of Mechanical Engineering.
