Abstract

PURPOSE: To prevent the generation of scratch, to improve the operating efficiency of the rolling work for the strip, and to improve the yield, at the recycling type rolling mill for the strip, by installing the strip storing unit of special mechanism, the welder, the coiler, etc.

CONSTITUTION: The strip storing units 2, 7, are constituted of the differential guide expandable and revolvable freely, the internal guide and the directional switch, and are internally provided with a mechanism which prevents the strips from mutual rubbing, temporarily stores and sends out the strip. The strip S is delivered from the uncoiler 5, and passes through the welder 6, the strip storing unit 7, the guide roll 8, the thickness detector 10, the rolling mill 1, the strip storing unit 2, and the shearing machine 3, and arrives at the guide table 9, where the strip S forms a loop and is recycled for rolling work; when the thickness becomes the specified value, the strip S is automatically cut depending on the command of the detecter 10, and is coiled into the coiler 4 through the storing unit 2; hereupon, the part being out away is welded by the welder 6 to the new strip supplied from the uncoiler 5, and forms a new loop and is supplied to the repeated rolling work similar to above. Since this method carries out the total rolling, the yield is improved.
