    摘要： A control device for controlling a rolling device which includes a pair of rolling mill rolls provided to sandwich a metal strip and an unwinding device uncoiling the metal strip at an entrance side of the rolling mill rolls in a traveling direction of the metal strip and which is configured to roll the metal strip by the pair of rolling mill rolls is configured to: after passing a tip part of the metal strip through the pair of rolling mill rolls in a state where a gap between the pair of rolling mill rolls is larger than a strip thickness of the metal strip, press the metal strip by the pair of rolling mill rolls in a state where exit-side tension applied to the metal strip is zero; make entrance-side tension applied to the metal strip by the unwinding device become larger than zero; and start rotation of the pair of rolling mill rolls.

    摘要： A metal rolling method for rolling a product strip by use of a rolling mill and a winder disposed on each of an entry side and a delivery side of the rolling mill, while causing the product strip to pass through the rolling mill back and forth, the method comprising:
    welding a leader strip held by the winder on the delivery side to an end portion of the product strip, and subjecting the product strip to reversible rolling by the rolling mill without rolling the leader strip and a welded part of the product strip to the leader strip, while giving tension from the winder on the delivery side through the leader strip to the product strip even near the end portion thereof; and
    cutting the leader strip at a position out of the welded part at an ending of an even ordinal number pass toward the winder on the entry side, and winding up the product strip including the welded part at the end portion onto the winder on the entry side without cutting out the welded part, followed by unloading a coil of the product strip thus wound up.

    摘要： The invention relates to a method for rolling a metal strip (6), especially a steel strip, in a reverse rolling mill (1) with a coiler located upstream and a coiler located downstream (4, 5). The metal strip (6) is wound off of the upstream coiler (4) with a strip thickness (d) and at a strip temperature (T) above a set temperature (T*). It is then passed through the reverse rolling mill (1) with a first draught of at most 5 % and at a speed (v) before being wound up by the downstream coiler (5). The speed (v) at which the strip is passed through the rolling mill is selected with the aim of ensuring that the strip (6) has reached the set temperature (T*) by the time it is wound up. The strip (6) is then wound off of the downstream coiler (5), passed through the reverse rolling mill (1) with a second draught of at least 10 % and wound up by the upstream coiler (4).
