The analysis of models for indirect measurement of surface temperatures in massive charge

Abstract

In this article are described the models for indirect measurement of the surface temperatures in the steel coil. The indirect measurement of surface temperatures is part of intelligent system of indirect temperature measurement in the steel coil. The major task of this system is to measure massive charge temperatures in the annealing process continuously in time. In the design and creation of these models we used the fact that only one direct measured temperature of the atmosphere was at our disposal – the one under the protection cover. The created and verified models are in the form of difference equations and the surface temperatures depend on the atmospheric temperature only.
