钢轨哪家好、陕西钢轨、圣霖贸易

轧钢设备的作业机座包含：1.机架，在其窗口内设备轧辊的轴承。2.轧辊，轧件在其间进行压缩3.轧辊轴承4.轧辊调整*，用来调整轧辊间的距离。5.导卫设备，用来坚持轧件的进出口方向。6.轧座，钢轨型号，机架固定在轧座上轧座固定在基础上。

The working seat of a steel rolling equipment c*ists of a 1. rack， bearing roller in its window. 2. rolls， the rolled piece is compressed between 3. roll bearing 4. rolls to adjust the structure， used to adjust the distance between the rolls. 5. guide equipment， used to adhere to the import and export trend of the workpiece. 6. rolling pedestal， the frame is fixed on the rolling base and fixed on the base.

由于轧辊在这个位置轧速相当慢，相对来说，轧辊与高温钢坯接触时间长，因此要有好的*热裂性、*剥落性、*冲击性和好的咬入性。此机架选择合金钢、半钢、合金球铁、或铁素体球铁均可满足要求。

Because the rolling speed of the roller at this status is rather slow，钢轨价格， relatively speaking， the contact time between the roller and high temperature billet is long，陕西钢轨， so it has good thermal cracking resistance， anti peeling property， impact resistance and good bite. The selection of alloy steel，钢轨哪家好， semi steel， alloy ductile iron， or Ferritic Ductile Iron on this rack can meet the requirements.
