Abstract
PURPOSE: To cancel the curling property being developed at the different speed rolling, by making the uncoiling direction of the coil on the entry side to be reverse to the coiling direction of the coil on the exit side, and by carrying out the rolling work turning the strip over for every pass.
CONSTITUTION: When the nonreverse rolling is carried out with different speeds of upper and lower rolls, the uncoiling direction of the coil on the entry side is reversed to the coiling direction of the coil on the exit side. Since the speeds of the strip S are different between the surface and the back face while the rolling work is carried out, a curling property is given to the strip S; however, the surface of the coil 5 being uncoiled comes to the back face in the coil being coiled. Accordingly, when thus coiled coil is rolled at the next rolling pass, the surface of the strip S, being passed through the gap of upper and lower work rolls 1, 2, of different speeds, comes to the back face; hereby, the curling property is canceled, and the strip with excellent quality can be manufactured.
