去する方法が提案されている。[Prior Art] In cold rolling, the rolling at the front and rear ends of the hot coil is not only unsteady, but also the metal flow changes and abnormal tension and shearing force locally act to lead to plate rupture. Sometimes. As a countermeasure against this, in Japanese Patent Publication No. 47-47780, the end portion is pretreated by a grinder, and in Japanese Patent Laid-Open No. 63-6283, the shear clearance is increased when the hot coil is sheared, and the work-hardened layer is specified. A method has been proposed in which it is collected in the upper layer part and is removed so that it can be easily maintained.

式でもその他の原理によるセンサーでも良い。[Embodiment] FIG. 1 is an explanatory view of an embodiment showing the present invention. From the previous step (usually the pickling step) in cold rolling to the coil 2
Is mounted on a conveyor saddle 3 of a coil conveyor (not shown) and is conveyed to a predetermined position. First, the coil tail end heat treatment apparatus 1 detects the coil end face by a coil end face detection sensor (not shown) and moves to the end face position. In the coil tail end heat treatment apparatus 1, the coil tail end detection sensor 4 and the induction heater 5 are rotatable by a rotating mechanism 6 and are coaxial with each other. The rotating mechanism 6 can be lifted and lowered by a lifter 7, and the coil tail end heat treatment apparatus 1 can be self-propelled on a slide base 8 in the coil axis direction. Next, the lifter moves the rotating mechanism to a predetermined coil inner diameter position and guides the coil tail end detection sensor to the coil inner diameter portion. The rotating mechanism detects the coil tail end by rotating the coil tail end detection sensor once in the inner diameter portion of the coil. With this information, the rotating mechanism guides the induction heater to the tail end of the coil and causes the tail end to follow. During this time, the induction heater heats the tail end of the coil and heat-treats it. After the heat treatment is completed, the coil tail end detection sensor and the induction heater are returned to their original positions. In this embodiment, the eddy current type sensor is used as the coil tail end detection sensor, but a contact type sensor or a sensor based on another principle may be used.

施可能である。The cold rolling to which the device of the present invention is applied is carried out not only for the cold rolling of the hot coil but also for the temper rolling after the coil tip shearing after annealing and the multiple cold rolling with or without intermediate annealing. It is possible.

まり、ロール原単位が向上する効果がある。[Effects of the Invention] As described above, according to the present invention, since the coil tip before cold rolling is heated by the induction heater and heat treatment is performed, the work-hardened portion of the metal strip in the previous step is softened and cooled. There is an effect that the metal flow at the coil tip in the hot rolling is normalized, breakage of the tip portion does not occur during rolling, and the yield and the roll unit are improved.
