Original Abstract

One aspect of the steel-product quality is the flatness of a steel plate. This is one of the reasons why it is iportant to describe and understand the process of steel-plate deformation during the cooling process. The temperature distribution has the largest impact on the deformation of a strip. The temperature distribution is affected by the cooling process. The cooling homogeneity or inhomogeneity is the most important factor influencing the final flatness of a cooled strip or steel plate. Inhomogeneous cooling can lead to large differences in the thermal distribution inside the material and also to high deformations. The cooling homogeneity is mainly influenced by the water distribution in the cooling section. The goal of this paper is to experimentally and numerically study and describe the deformation process of a hot steel plate during the cooling process. To meet these goals, experimental measurements of a cooled steel plate were carried out and the boundary conditions and temperature field were obtained. Based on this data, two numerical models were created. The first numerical model focused on the cooling process, the thermal-field simulation and the input-data preparation for the next step. In the next step, the second numerical model was generated using the finite-element method and an analysis of the structure and deformation of the steel plate was simulated. The description of the shape deformation of cooled steel plates should lead to an improved flatness of final products.
