Abstract
A processing line for rolling metal slabs into strip thicknesses along a substantially horizontal pass line includes the utilization of an intermediate mill formed of an upstream coiler furnace and a pair of coiler furnaces downstream of a reversing mill where the downstream coiler furnaces are in vertical alignment with one above the pass line and the other below the pass line. The method of rolling includes reducing a transfer bar in the reversing mill and coiling it in one of the downstream coiler furnaces. The coil is then passed back through the reversing mill into the upstream coiler furnace. Thereafter, the coil passes through the reversing mill for the third time and is again coiled in one of the downstream coiler furnaces. The coil is then uncoiled and directed into the finishing train while a subsequent coil is processed in the reversing mill utilizing the empty downstream coiler furnace. The rolling of the workpiece through the intermediate mill is done independent of the finishing train.
