[0002] The hot rolling process is roughly divided into heating, rough rolling, finishing rolling, coiling, transportation, finishing and other processes. Among them, the hot output roller is an important equipment on the hot rolling production line. It is located between the finishing rolling unit and the coiling unit. It consists of hundreds of rollers with a total length of more than 100 meters. Since the strip temperature is as high as 450-940℃, in order to prevent the roller from getting stuck due to heat, a water cooling device is designed under each roller to cool the roller.
[0003] When the roller is running at high speed, the cooling water forms a layer of water mist on the roller surface under the action of centrifugal force, which reduces the friction between the strip and the roller surface. This will affect the stability of the thin plate head on the roller during the threading operation. At the same time, impurities on the roller surface need to be cleaned in time after falling. A heat output roller with a drainage device is now proposed. Utility Model Content
