Abstract
PURPOSE: To lighten the rolling load at rolling the strip, by interposing the center work roll between two outer work rolls, by backing up the center work roll with the backup roll, and by independently driving each of outer work rolls.
CONSTITUTION: At rolling the metallic strip 9, the peripheral speed of outer work roll 2 is adjusted by the driver 12 so as to be equal to the linear speed of the strip 9 given by the tension roll 8; the peripheral speed of another outer work roll 2' is adjusted by the driver 12' so as to be a value determined from the thickness ratio of strip 9, 9', respectively before and after the rolling work; hereby, the peripheral speed of outer work roll 2' becomes equal to the linear speed of the strip 9' due to the tension roll 8'. Accordingly, the strip 9 winds round outer work rolls 2, 2', without causing slip. The center work roll 1, and backup rolls 3, 3', receive upward reaction through the strip 9', and the center work roll 1 tends to cause bending; however, since the large diameter backup roll 3' of great rigidity supports the center work roll 1 through the small diameter backup roll 3, the rolling load to be impressed on edges of the strip 9, 9', is lightened, and the edge drop is diminished.
