Abstract

A rolling system has a rolling mill a rod workpiece, a wire block comprised of at least two roll stands downstream of the rolling mill, and a calibrating block comprised of three roll stands spaced apart in the direction downstream of the wire block. The workpiece is passed in the direction downstream in the direction from the rolling mill through the wire block and thereafter through the calibrating block with thickness reduction in each block. The gaps of the stands of the calibrating block are set at a fixed spacing and not varied during a rolling operation. A sensor measures the thickness of the workpiece upstream of the calibrating block, and gaps of the roll stands of the rolling mill or wire block are adjusted in accordance with the measured thickness such that the workpiece has a predetermined thickness on entering the calibrating block.
