般在板边缘较薄,扎或纵厚度偏差就叫做板凸度。如果板凸度足够大,板厚偏差可以达到一定值,以至于钢板不适用于在严格要求板厚精度的场合。当厚度偏差增大(在板宽方向上厚度不同)导致在材料设计后产品损失中应考虑增加板厚边缘。
It is thinner on the edge of the plate, and the deviation of the ligation or longitudinal thickness is called the plate convexity. If the plate convexity is large enough, the thickness deviation of the plate can be reached to a certain value so that the steel plate is not suitable for the situation where the thickness of the plate is strictly required. When the thickness deviation increases (the thickness is different in the width of the plate), the thickness edge of the plate should be added to the loss of the product after the material is designed.
机架是轧钢机的主要部件,它在轧钢过程中承担金属变形给予的负荷。因此要求机架有足够的强度和刚度,以保证设备安全和产品质量。型钢轧机的机架形式较多,常见的机架形式有开口式机架、闭口式机架和半闭口式机架3种。
The frame is the main component of the rolling mill, which bears the load given by the metal deformation during the rolling process. Therefore, the frame is required to h***e sufficient strength and stiffness to ensure the safety of the equipment and the quality of the product. There are more frame forms of the steel mill. There are 3 kinds of common frame forms: open frame, closed frame and half closed frame.
短应力线轧机具有如下优点:
⑴容易实现负公差轧制,因为轧机的高刚度保证了产品的。
⑵可实现轧机左右两个轴承的对称调整,这对于稳定轧制条件,提高作业率,节省检修和更换导卫、横梁时间等具有重要意义。
Short stress line mill has the following advantages:
It is easy to realize negative tolerance rolling mill, because of the high rigidity to ensure high precision products.
The symmetric adjustment can achieve about two rolling bearings, the stable rolling condition, improve operation efficiency, s***ing maintenance and replacement has important significance to guide and beam time etc.
楔横轧工艺的基本原理是,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.
