A mathematical model of thermophysical processes is constructed on the basis of an integral form of the heat-conduction equation for a hot-rolling mill. The boundary conditions on the surface of the metal are determined, including for the case when the metal is in the accelerated-cooling section of the mill. The model is used to create a universal software package for solving one- and two-dimensional heat-conduction problems in different coordinate systems. The capabilities of the package are explored by modeling the accelerated cooling of a plate in the line of the 5000 hot-rolling mill at the MMK and the cooling of a cylindrical semifinished product with the use of a single nozzle. The calculated results agree with the results obtained under factory conditions. © 2012 Springer Science+Business Media, Inc. Source
