  • Patent number: 5423926
    Abstract: A plate temperature and an emissivity are determined at the outlet of an insulated heated zone, and compensations are established which reduce deviations between the respective measured values and the respective target values. A heat input is compensated for in accordance with the greater one of the compensations relating to the plate temperature and the emissivity, respectively. For a U-pattern material, .DELTA.Q is previously added to the heat input for the leading and the trailing end portion of the material. The band steel is irradiated by laser radiation at the outlet of the heating zone in order to detect the degree of alloying on the basis of the intensity of reflected radiation. When an unalloyed surface is detected, a target value of the heat input is modified. ITV camera is used to determine the optical reflectivity of the surface of the band steel at the outlet of a cooling zone in order to detect the degree of alloying.
