CONSTITUTION: A device for removing cooling water on a web of an H-beam comprises a compressor(60), a high-pressure tank(70), and front and rear air nozzle pipes(90,100). The high-pressure tank is connected to the compressor. The high-pressure tank is formed with an opening/closing valve(110) on an outlet. The front and rear air nozzle pipes are connected to the high-pressure tank and are installed in the front and rear of a rolling mill. The lower part of the front and rear air nozzle pipes is bent to the air nozzle pipe. Multiple branch pipes are formed on the lower part of the front and rear air nozzle pipe.
