Abstract (en)
[origin: WO8806497A1] The method provides for measuring the tension of the strip and calculating the difference in tension at the inlet of each descaling zone and at its outlet, comparing said difference in tension with a preset difference value and compensating the deviation of the tension difference from the preset value by changing the pressure of the powder on the strip in each descaling zone.
