摘要： A method and system for controlling the temperature in a furnace such as a continuous feed controlled atmosphere furnace includes an upstream thermocouple in a first area of the furnace, a second thermocouple in a second area of the furnace, and a heater control system. A sensed temperature from the upstream thermocouple is used to generate a control signal for a heater associated with the first area of the furnace. The sensed temperature from the first area of the furnace is further used to modify a set point that is compared to a sensed temperature from the second thermocouple. A control signal for a heater associated with the second area of the furnace is generated based upon the comparison of the modified set point to the sensed temperature from the second thermocouple.
