Abstract
PURPOSE: To remove scale efficiently, by cooling high temperature steel coil directly in a liquid bath to form a scale layer, and mechanically crushing and removing the scale layer while uncoiling.
CONSTITUTION: After hot rolling, a high temperature coil 1 is bundled with a coil band as required, and mounted on a mount 3 of a water cooling pit 2, and is immersed in cooling water 4 to be cooled. In this case, the coil temperature after cooling should be preferably less than 250°C and more than 70°C. The cooled coil 1 is let off by a let-off machine 5, and the rear end of a preceding strip and the front end of the coil 1 being let off are connected by welding with a welding machine 7, so that a strip 13 is supplied continuously. The strip is controlled of the tension by a bridle roller 11, and rolled at draft of 0.5W4% by means of a skin pass mill 12, and the scale layer is crushed, and the strip is finally descaled by a brushing device 6.
