On parabolic approximation of the temperature field of slabs during heating in continuous furnaces

Introduction. In the conditions of increasing requirements for the quality and efficiency of metal heating before rolling, the task of creating and improving the mathematical support of automated process control systems (APCS) for heating furnaces is quite relevant. Purpose of the study. To establish the specifics of the implementation of the parabolic approach mentioned in the literature to the description of the temperature fields of billets during heating in continuous furnaces.
