Functional content and structure of a software package for modeling the temperature of a hot-rolled strip with interval parameters

The article considers the structure and functional content of a software package for modeling the temperature regime in the strip and working rolls during hot rolling of steel. Software with real input parameters and interval input parameters has been developed for modeling of temperature. This article discusses software with interval input parameters, its content and design. The article presents the structure of software for modeling temperature in interval values, thermal conductivity equations for solving problems of modeling temperatures in the deformation zone, on the interstand gap and intermediate roller with interval input parameters. The scheme of the temperature modeling algorithm is considered, taking into account the configurations of cooling systems at a hot rolling mill, and an algorithm for finding friction coefficients taking into account interval input parameters is separately presented. The main functions of the implemented library of classical interval arithmetic are described with an indication of the mathematical description. The description of the interface for software modeling the temperature of the strip with interval input parameters and some functions is given. Groups of software input parameters are presented with a description of possible values and their units of measurement.
