Process and device for regulating the calorific output in a continuous annealing and processing line for continuously cast metal products

An arrangement for regulating an annealing power in at least one annealing section of a continuous annealing and processing line for continuously cast metal products, comprising:

• a first measuring equipment (7) for measuring a passing speed of the continuously cast metal product (D) passing through the continuous annealing and processing line and for outputting a representative electrical signal,
• a second measuring equipment (30, 31, 32) for measuring an instantaneous voltage value on the annealing section and for outputting a representative electrical signal,
• a first determining equipment for determining an effective voltage value (U.sub.e) on the basis of said measured instantaneous voltage value on the annealing section,
• a control unit (50) for forming a control signal from said determined effective voltage value for changing the voltage supplied to the annealing section in order to obtain a predetermined annealing power value dependent on the speed measured,
• a third measuring equipment (40, 41, 42) for emitting a measuring signal representative of annealing current flowing in said at least one annealing section, and
• a second determining equipment for determining an effective current value on the basis of said measured instantaneous current value,
• said first and second determining equipment including a first (35, 36, 37) and a second (45, 46, 47) transforming equipment having a digitizing unit for digitizing the measured instantaneous values of voltage and current, and each transforming equipment is followed by an integrating equipment for determining the corresponding effective value from this digitized value for a predetermined short period of time, and
• the control unit is designed as a processor and includes a multiplication equipment for calculating the annealing power actually supplied to the respective annealing section from said calculated effective values.
