在二辊式机架中,进行着型材(圆钢、方钢、六角钢及花样型材)及窄扁材的热轧。在某些情况下,在这种类型的机架中也轧制冷状态的窄扁材。轧材成品的尺寸精度与在轧制过程中金属作用于轧辊的压力变化时轧辊、牌坊及工作机架的其他零件(压下螺杆、压下螺母、压下螺杆垫板及轧辊辊颈部轴承座)的弹性变形的变化有关。金属作用于轧辊的压力之所以会发生变化,是因为决定轧辊中金属变形条件的因 In two-roll racks, hot rolling of profiles (round bar, square steel, hexagons and pattern profiles) and narrow webs is carried out. In some cases, cold-shaped, narrow flat bars are also rolled in this type of rack. The dimensional accuracy of the rolled stock product and other components of the roll, archway, and work racks when the metal is acting on the roll during the rolling process (reduction of the screw, reduction of the nut, reduction of the screw backing and roll roll neck bearing Block) of the elastic deformation of the change. The reason why the pressure of the metal acting on the roll changes is because the reason for determining the deformation condition of the roll in the roll
