Patent ID: 8490451

Claim:
Method of rolling metal strip, wherein the metal strip initially travels through a pickling line and then between two reversing reels, through a reversing rolling mill, and wherein the end of a metal strip is welded to the beginning of a next following metal strip before the pickling line, and wherein prior to reeling the finished rolled metal strip, a separation of the welded together metal strips takes place, comprising the following sequence: the metal strip A emerging from the pickling line travels through two roll stands ( 3 , 4 ) of the reversing rolling mill and is then reeled onto the reversing reel ( 1 ) arranged following the reversing rolling mill; wherein, prior to entering the pickling line ( 5 ), the beginning of the next following metal strip B has already been welded onto the end of the metal strip A; this strip beginning of metal strip B is now rolled together with strip A over a length which corresponds to an initial winding length up to a tension-buildup and also travels onto the reversing reel ( 1 ); during subsequent reversing, the metal strip B is separated from the metal strip A by shears ( 6 ) such that the already rolled strip beginning of the metal strip B remains with the remaining metal strip B which has not yet been rolled; subsequently the reversing rolling of the complete metal strip A takes place, wherein after emerging from the reversing rolling mill, the metal strip A runs onto the reversing reel arranged upstream of the reversing stand; as soon as the metal strip A is completely on the reversing reel ( 2 ), the metal strip B is fed to the reversing rolling mill and the above sequence is repeated with this metal strip B and a subsequent metal strip C.
