<p>A shape-rolling mill for working metallic section material, which is capable of correcting mill rigidity in a transverse direction parallel to the axes of work rolls by means of a fluid pressure mechanism. The sectional roll-pass configuration is corrected by adjusting the rigidity in the axial direction of the rolls in relation to the rigidity in the vertical or reducing direction under control of the fluid mechanism. In one preferred form, a second fluid pressure mechanism is provided for correcting the mill rigidity in the reducing direction. The second fluid mechanism controls the vertical rigidity of the mill to allow a greater freedom to the adjustment of the ratio between the longitudinal and transverse rigidities of the mill. The sectional shape of the metallic work is corrected by balancing the vertical and transverse mill rigidities.</p> |
