轧辊由辊身、辊颈和轴头二部分组成。辊颈安装在轴承中，并通过袖承座和压下装置把轧制力传给机架。铂头和连接轴相连接，传递轧制扭矩。轴头有三种主要形式；梅花轴头、万向轴头、带键槽的或圆柱形轴头。

The roll is of two parts of the roller body, the neck of the roll and the shaft head. The roll neck is installed in the bearing and passes through the sleeve bearing seat and the press down device to the rack. The platinum head is connected to the connecting shaft to transfer the rolling torque. There are three main forms of the shaft; the shaft of a plum, a universal shaft, or a cylindrical shaft with a keyway.

修正精度高，涂层厚度从几微米到几毫米，可对金属工件呈现磨损、划伤、、裂纹、破损变形、硬度降低、损害等缺点进行堆积、封孔、补对等修正功用，只须打磨、抛光，也可进行车、铣、 刨、磨等各类机械加工，以及电镀等后期加工。

The thickness of the coating is high, and the thickness of the coating is from several micr*** to a few millimeters. It can be worn, scratched, pinholes, cracks, breakage and deformation, hardness reduction, damage and other shortcomings to accumulate, seal, and compensate for the defects, such as grinding, polishing, milling, milling, grinding and other kinds of mechanical processing, as well as electroplating later processing.

当轧制其它型材时，可以用水平机架更换机架。水平机架的轧辊有很深的孔型，而机架没有。

较大直径的水平轧辊确定型钢的的形状，而较小直径的一对立辊用于轧制边部。当坯料穿过传统机架和机架精轧轧辊时，可以获得很好的表面光洁度和尺寸公差。

When rolling other profiles, the universal rack can be replaced with a horizontal rack. The roll of the horizontal frame has a very deep pass, but the universal rack does not.

Horizontal rolls with larger diameters determine the shape of the section steel, and a pair of rolls with ***aller diameters are used for rolling edges. Good surface finish and dimensional tolerance can be obtained when the blank passes through the conventional stand and universal stand finish rolls.
