开口式机架由机架底座和上横梁组成。
开口式机架是型钢车间常见的一种机架形式。这种机架的优点是制造简单，装卸、换辊方便。其缺点是强度和刚度较低，轧辊辊跳值较大，影响产品精度，350轧机谁家好，故只适用于大型轧机。
The open frame is of the frame base and the upper cross beam.
The open frame is one of the most common forms in the steel workshop. The advantages of this frame are simple manufacturing， loading and unloading， and convenient for roll change. Its disadvantage is that its strength and stiffness are low， the roll roll value is larger and the precision of the product is affected， so it is only suitable for large rolling mill.
楔横轧工艺的基本原理是，350轧机哪家好，将加热后的棒材送入两个同向旋转的带有楔性凸起的模具中间，棒材在模具的带动下，作与模具反向的回转运动，同时材料发生径向压缩变形和轴向延伸变形，从而成形阶梯轴类零件。
The basic principle of the cross wedge rolling process is to send the heated bar into the middle of two same revolving moulds with wedge-shaped protrusi. The rod is driven by the mold to make the reverse rotation movement with the mold. At the same time， the material has radial compression deformation and axial extension deformation， thus forming a staircase type part.
四棍轧机的工作辊直径较小，传递轧制力矩，轧延压力由直径较大的支承辊承受。这类设备的主要优点是相对刚度较大，压下量大、轧延力小，350轧机生产商，可轧制较薄的板材，也包括有可逆和连轧两种。
The working roll diameter of the four bar mill is **all， and the rolling torque is transferred. The rolling pressure is borne by the backup roller with larger diameter. The main advantages of this type of equipment are relatively large stiffness，350轧机， large reduction， low rolling force， thin rolled sheets， and reversible and continuous rolling two.
