论述在作者研制的三铰拉杆方柱（即平面自位）型高刚度轧机基础上，研制的３５０空间自位型高刚度轧机，配置沿轧制力和水平力（轧制线）作用方向同时确保四列滚动轴承每列和轧辊轴向调节螺纹机构均载的自位机构。本轧机在８架棒材连轧机头一架上使用一年证明，四列滚动轴承和轧辊轴向调节螺纹机构均未发生损伤或烧熔，虽发生几次断辊事故，但轴承和螺纹机构仍完好无损。 On the basis of the high stiffness mill with three hinged rods developed by the author (that is, plane self), this paper describes the 350 space self-standing high rigidity mill with the function of rolling force and horizontal force (rolling line) At the same time to ensure that each row of four rows of rolling bearings and roller axial adjustment screw mechanism are self-owned institutions. The mill in the first eight bar rolling mill to prove the use of a year, four rows of rolling bearings and roller axial adjustment screw mechanism were not damaged or burning, although the occurrence of several broken roller accident, but the bearing and the screw mechanism is still Undamaged
