PURPOSE:To roll ultrathin hot rolling materials with good efficiency by suspending the top of the rolling materials after rough rolling during traveling, returning the same in the direction opposite from the traveling direction, superposing the rolling materials in two plies and subjecting these to finish rolling. CONSTITUTION:The top a1 of rolling materials (a) under traveling on a delay table 1 after completion of a rough rolling stage is lifted by a lifter 2 actuated by an oil hydraulic cylinder near the finishing stand (not shown), and is hoisted by a traveling crane 3 via a tongue 31. Thence, the lifting device 2 resumes the original horizontal position, thereby forming a part of the delay table. The crane 3 moves in the direction opposite from the material (a) and superposes the top a1 on the material (a) in conformity with the bottom a2, thereby superposing these in two plies. The edges of the upper and lower rolling materials (a) are aligned by side guides 4 provided on both sides of the table 1 and are crushed of the loop a3 formed in the bent position by a press 5, thence these are sent for the finishing stage. |
