Surface roughness transformation and deformation of the scale of hot rolling
In hot strip rolling, the oxide scale surface significantly affects the roughness of the strip which, in turn, affects the product quality through subsequent downstream processing via the pickle line and the five stand cold mill. In this paper, we focus on the modelling of the hot rolled strip with oxide scale and quantify the effects of various rolling parameters on the final surface roughness. A Finite Element Model (FEM) is used to simulate the surface roughness transfer of the oxide scale and the steel surface roughness in hot rolling.
