Software for Modeling the Temperature Distribution of Strip and Work Rolls during Hot Rolling

Abstract

The software for calculation the thermal conditions of the hot rolling mill is developed. The software includes several mathematical models of the temperature distribution along the thickness of the strip and working rolls. The base of all models is the heat equation with different boundary conditions. The type of model is defined by the current zone (rolling gap, interstand gap, cooling zone on the surface of the roll). The heat flows in the boundary conditions for a strip at the interstand gaps are taking into account the parameters of interstand cooling systems. The information about the construction and settings of the nozzles and roll anti-peeling systems is used for calculating the heat flow on the surface of the working roll.
