PURPOSE: A device and a method for controlling the temperature of a thermal process furnace are provided to minimize surface defect of a thick plate and reduce maintenance costs for the formation of inert gas atmosphere. CONSTITUTION: A device for controlling the temperature of a thermal process furnace comprises a first sensor(200), a second sensor(210), a flow controller(400), and a controller(300). The first sensor is installed inside a thermal process furnace which transfers and thermally processes a thick plate. The first sensor detects the surface temperature of the thick plate. The second sensor is installed inside the thermal process and detects the surface temperature of a roller table. The roller table comprises a roll shaft and a roller. The flow controller is connected to the burner and controls the flow rate of the gas supplied to the burner. The controller connects to the first and second sensors and the flow controller. The controller controls the opening degree of the flow controller according to the temperature difference and setup value. |
