                           directly to the industrial apparatuses. That is why even with a refined
                           calculating procedure, the use of experimental data for rectification obtained at
                           hot stand remains an important problem. In Fig. 17 the technological scheme of
                           the installation of Prof. Billet, taken from [86] is presented.
