PURPOSE: A device for decreasing the temperature of a heating furnace is provided to decrease the inner temperature of the heating furnace more rapidly and to improve the efficiency of heat-treating a test piece and productivity. CONSTITUTION: A device(10) for decreasing the temperature of a heating furnace comprises a cooling unit(20), an exhaust pipe(30), a damper(32), and a blowing fan(34). The cooling unit supplies gas for decreasing the inner temperature of the heating furnace where the heat-treatment with respect to a test piece is performed. The exhaust pipe is installed in the heating furnace and discharges heat inside the heating furnace. The damper is installed in one side of the exhaust pipe and opens/closes the exhaust pipe. The blowing fan is connected to the exhaust pipe and discharges the heat inside the heating furnace. |
