Abstract
A single-point temperature control system is used with a multi-section furnace to control the exit temperature of a metal workpiece discharged from the furnace. The furnace consists of at least first, second and third sections. The temperature is sensed at the single temperature set point in the second section and compared with a desired set point temperature. The power to the second section is adjusted in order to maintain the desired set point temperature so that the metal workpiece exits the furnace at the required temperature.
