<p>Rolling plant for hot rolling metal workpieces comprises a reversing roughing mill (12), a continuous finishing mill (15) spaced from the roughing mill (12) and an intermediate coiler (17) which can be retracted to an inoperative position clear of the pass-line. In the penultimate forward pass of the roughing mill (12), the coiler (17) is in its inoperative position and the workpiece (S1) is rolled to a length greater than the coiler - roughing mill spacing but less than the finishing mill - roughing mill spacing, the leading end of the workpiece passing under the coiler (17). In the final forward pass, the coiler (17) is in its operative position on the pass-line and effects coiling of the workpiece (S1). Subsequently, the coil is uncoiled and led out to the finishing mill (15).</p> |
