Abstract
The most important objective of developing technologies for the process of hot sheet rolling is to determine the strip temperature in the technological line of the mill. In this paper, a mathematical model has been developed for calculating the temperature schedules of strip rolling on hot rolling mill 2300/1700 of PJSC Chelyabinsk Metallurgical Plant. The mathematical model takes into account the steel temperature loss during rolling and transportation along the mill line, heating of the strip during its deformation, heating of the billet in an intermediate reheating furnace, and a drop in the temperature of the rolled products, when passing through cooling facilities. Temperature changes are detect-ed and recorded along the mill line, from reheating continuous furnaces to hot strip coilers. Checking the developed mathematical model adequacy by comparing the calculated and experimental data has shown convergence sufficient to carry out calculations in the analysis and improvement of the applied rolling schedules and development of new ones. The paper provides an example of using the developed mathematical model to calculate the temperature parameters of rolled products. The mathematical model can be used both for scientific research and as a tool for engineering calculations of sheet rolling temperature schedules.
