Abstract

PURPOSE:To obtain a strip of good quality in small fuel unit without accurate controlling of operating speed by coiling a rough rolled sheet bar once, moving the same in a heat retained state, uncoiling it and joining it to a sheet bar under rolling in joining both sheet bars. CONSTITUTION:A sheet bar 12 roughly rolled with a rughing mill 11 is taken up in the form of a coil with a coil box 13. This coil 14 is moved into a heat retaining box 15, and while it is waiting for rolling it is held in the heat retained state. A sheet bar coil 17 withdrawn from a box 15 is uncoiled to a sheet bar 18 which is cut together with the preceding sheet bar 20 under finish rolling with a finishing mill 19 respectively at their leading ends and tail ends with a shear 21. Next, the bar 18 moves closer to the bar 20; thereafter, both travel at the same speed, and while a joining machine 22 travels synchronously with the speed thereof, it joins the bar 18, 20 by welding or pressure welding.
