Abstract

Analytical approximations that can be used together with the numerical codes to obtain estimates on the temperature distribution inside of the cooled steel strip/plate are discussed. While numerical simulations can give accurate answer after the time required for calculations, the analytical approximations show how thickness and cooling rate affect the temperature distribution. We also present development of graphical user interface interaction with numerical codes for the use in designing and tuning of water cooling schedule for hot rolling strip and plate mill. Interaction of the numerical codes with user friendly frontends have been developed for the following tools: a heat conduction simulation tool for hot strip mill, a tool for calculating phase transformations for user defined cooling paths and a tool for calculating the required cooling water to cool a steel strip to a desired temperature. The functionality and interaction of the tools with the numerical codes is described.
