Abstract

Problem Statement. In the current conditions, the process of controlled rolling with accelerated cooling is widely used in the world practice of rolling divisions. One of the most important scientific and practical tasks in the development of technological modes and learning of the production of innovative types of rolled products is to select temperature parameters of the process and the cooling schedule, ensuring the formation of the required structure and properties of finished products. At the same time, the issue of predicting the temperature state of steel and achieving the specified treatment parameters in industrial conditions remains relevant. Objective. The research is aimed at selecting the accelerated cooling process schedule for coils based on the simulation of the thermal state of steel along the strip section. Methods Applied. Modeling was carried out in the Deform-3D software suite. The authors used in the research their finite element model developed for calculating the thermal field during controlled rolling and accelerated cooling of steel on hot strip mill 2000. The model factors into the processes of heat release during rolling, heat transfer to the rolls, as well as cooling of steel, when in contact with water and air. Results. The authors proposed a finite element model used to predict the cooling rate and the distribution of the temperature field along the section of rolled products. Having analyzed the results of finite element modeling, the authors selected a cooling schedule providing for enabling of the first 19 sections of the unit in a sequential order. This contributes to achieving the required treatment schedules subject to the design features of the operating equipment. The experimental industrial tests showed high convergence of calculated and experimental data. An error of the obtained data does not exceed 3%.
