PURPOSE:To prevent temperature drop and to improve width accuracy by slanting the roll axes of a vertical mill to be installed to the reverse direction to the advancing direction of a rolling material to increase the width adjusting quantity. CONSTITUTION:A pair of vertical rolls having smooth surfaces are previously slanted by a proper angle theta deg. to the reverse direction to the advancing direction of a rolling material S, which is bitten by the slantly set vertical rolls. The end-edge part of material S bitten by the vertical rolls deforms upward, and simultaneously, tends to deform curvedly downward by a bending moment due to the movement of a point of application of a rolling load with respect to the material S caused by the downward deformation of said part. These deformations collide with table rolls arranged between vertical rolls and are held by their reactions, and the bending moments with respect to the material S caused by the rolling load under the width-adjusting rolling reduction are maintained in well equilibrium. |
