た。2. Description of the Related Art Ultra-glossy steel sheets used for various purposes such as reflectors are required to have a high gloss of about 800 to 900 by a gloss meter (GS20 °). The super-glossy steel sheet is manufactured by performing various heat treatments after rolling, but when the super-glossy steel sheet is manufactured in a batch system, there are the following problems.

が強く望まれている。In the process of manufacturing an ultra-glossy steel sheet such as an electrolytic cleaning line or a temper line, when the coil for an ultra-glossy steel sheet is rewound, winding tightness occurs at the inner peripheral portion of the coil. This winding tightness occurs due to unbalance of winding tension when winding the coil. When winding tightness occurs in the inner peripheral portion of the coil, the steel plate surfaces rub against each other when the coil is unwound, and scratches are formed on both surfaces of the steel plate.
Therefore, an excellent quality super-glossy steel sheet cannot be obtained, and it is necessary to scrap the steel sheet where scratches occur depending on the degree of the scratches, resulting in a decrease in product yield. In particular, it is strongly desired to reduce the amount of scrap as much as possible in a super-glossy steel plate whose manufacturing cost is higher than that of a normal steel plate.

Therefore, an object of the present invention is to provide a method capable of easily preventing the tightening of the inner circumferential portion of the coil that occurs when the coil is unwound.

It is characterized by preventing it.

しい。Next, an embodiment of a method for preventing tightening of the coil inner peripheral portion of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a method for preventing winding tightness of an inner peripheral portion of a coil according to the present invention. As shown in FIG. 1, the present invention is characterized in that the ends of the steel plate for several turns of the inner peripheral portion of the coil 1 are fixed in advance by welding. The welded portion 2 may be provided at several places, and TIG (tungsten inert gas) welding is preferable as the welding method.

る場合には、この発明は特に有効である。By fixing a few turns of the inner peripheral portion of the coil 1 by welding in this manner, the coil 1 becomes exactly the same as the state of being wound on the core material. It is possible to easily prevent winding tightening of the inner peripheral portion. Therefore, when the coil is unwound, scratches do not occur on the inner circumference of the coil. The fixed portion of the coil 1 that is fixed by welding is scraped, but this amount is significantly smaller than the amount of scrap that is generated due to scratches caused by winding tightening. Therefore,
The present invention is particularly effective when the coil 1 is a coil for an ultra-glossy steel plate, which has a high manufacturing cost.

As is clear from FIG. 2, according to the method of the present invention, the rate of the defective products due to the scratches is significantly reduced.
