Determination of Temperature Dependent Cooling Intensity for the Simulation of In-line Heat Treatment

Popis výsledku v původním jazyce

The production of steel by using hot rolling represents one of the biggest parts of steel production. The rolled materials final properties do not depend only on the chemical composition but also on the cooling process after rolling. This article concerns the simulation of heat treatment of steel products during the in-line process. The purpose of these simulations is to determine future cooling curves, the cooling rate and the final structure of the material in advance. Simulations can be carried out for many steel grades. However, for these simulations, knowledge of cooling intensity in cooling sections is necessary. This article specifically focuses on the determination of boundary conditions from the experimental measurements which are carried out as close to plant cooling conditions as possible. During these measurements two line infrared-scanners measured surface temperature distribution across hot steel before and after the cooling section in laboratory conditions. The objective of laboratory measurement was to establish data for a new inverse approach for computation of the heat transfer coefficient during the cooling process. The algorithm for the inverse method and example of obtained results are described. Obtained cooling intensities are applied and the simulation of heat treatment is presented as well.
