<p>PURPOSE:To realize continuous hot rolling with high productivity, which is free from the action of excessive tension to cause the rupture of a plate during the continuous hot rolling of a joined billet. CONSTITUTION:After butting and joining the rear end part of a roughly rolled preceding billet 1 and the tip part of a succeeding billet 2 following after this billet 1 while holding, pressing and supporting them by a clamp or a pinch roll, they are sent to a finish rolling equipment. When continuously performing hot rolling to them, they are rolled after preparing a drawing down schedule by which the holding, pressing and supporting parts and the joint of the billet at the time of the joining treatment of the billet, are not simultaneously bit by a drawing down roll.</p> |
