To find out the cause of the large volume usage of cooling water in the air-mist spray cooling system for a machine at Pohang Steel Works, the nozzle characteristics and heat transfer during the secondary cooling process were analyzed and compared with those for another machine which was identical in geometry but had a different method of cooling of the water-spray. The reduced cooling efficiency in operation of the air-mist cooling was explained by spray water distribution along the strand widthwise direction and air pressure acting on the air-mist nozzles. Trials optimizing air-mist cooling at the former machine was desired.
