Abstract (en)

[origin: US7181943B2] Strip is descaled in a rolling line having a scale scrubber and a finishing line downstream of the scale scrubber. The strip is sprayed with water on its upper and under sides at a descaling pressure in the scale scrubber. In the scrubber the strip is treated with water at a multiplicity of locations spaced from one another in the travel direction. A furthest downstream location at the under side is spaced downstream from a furthest downstream location at the upper side. Rolling torques of at least one rolling mill of the finishing line are measured above and below the strip and control parameters are produced corresponding thereto. These parameters are fed to a control circuit and used thereby to adjust quantities of water sprayed at the locations against the upper side and under side of the strip upstream of the finishing line.
