摘要： A method and apparatus for rolling steel material into steel products having flanges such as rails and H-shaped products by use of a universal rolling mill wherein the cross section along the direction of axis of the vertical roll of the universal rolling mill has a convex shape. Therefore, the rolling by such vertical roll gives a reduction of nearly V-shaped concentration to the part of the steel material contacting said vertical roll and to be made into a flange.

摘要： 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.
摘要翻译：一种用于加工金属截面材料的成型轧机，其能够通过流体压力机构在平行于工作辊的轴线的横向上校正轧制刚度。通过在流体机构的控制下相对于垂直或减小方向的刚度调节辊的轴向刚度来校正剖面滚道构造。在一个优选形式中，提供了第二流体压力机构，用于校正在还原方向上的研磨刚性。第二流体机构控制研磨机的垂直刚度，以允许调整磨机的纵向和横向刚度之间的比率的更大的自由度。金属制品的截面形状通过平衡垂直和横向研磨刚度来校正。
