Abstract
When a strip of e.g. hot steel is rolled by a rolling or roughing mill, scale develops on the surface of the strip which must be removed. The strip is passed over a bending roller which bends the strip and causes cracks in the scale. Then water is injected onto the strip to wash the roller and lift of the scale. Inertia then causes the water and scale to leave the surface of the strip and pass to a collection device whose water collecting surface is out of contact with the strip and on the opposite side of the bending roller from where the water is injected. In this way the time of contact of the water with the strip can be kept short and the strip is not damaged by contact with the collection device.
