  • Temperature control apparatus
    Patent number: 4359210
    Abstract: Apparatus for controlling furnace temperature particularly in an annealing furnace used for annealing elongated product, such as pipe and tubing, on a continuous basis. The apparatus includes a pyrometer used to produce an electrical signal proportional to the temperature of the workpiece immediately after heating by an induction coil in the furnace, means for comparing this electrical signal to a set point signal proportional to the desired temperature of the workpiece and if these signals differ a control signal is produced to either increase or decrease the power input to the induction coil to correspondingly increase or decrease the temperature of the workpiece to the desired temperature.
