650轧机-圣霖国际650轧机-圣霖国际(推荐商家)

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，650轧机厂家，压下量大、轧延力小，圣霖国际650轧机，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， large reduction， low rolling force， thin rolled sheets， and reversible and continuous rolling two.

轧制时毛坯的位置固定，圣霖650轧机，因此不需设置侧向支撑毛坯的导向尺。总之，它适用于轧制复杂外形结构，精度要求高，零件品种变换很多的情况。但其行程大小受到限制，所以，变形程度也受到影响，同时，板式轧机有空行程，故影响到生产率和变形程度都不能很大。

The of the blank is fixed during rolling， so there is no need to set the guide bar of the side supporting blank. In short， it is suitable for rolling complex shape structure with high accuracy and many varieties of parts. But the stroke size is limited， so the degree of deformation is also affected. At the same time， the plate mill has an empty tr**el， so the productivity and deformation can not be very large.

辊系快速整体更换不需吊车，650轧机，采甩轧辊牵引小车和横移台车结合的换辊方式，导卫横梁安装在轧机轴承座上，更换轧辊时，导卫及横梁随辊系整套从牌坊窗口中拖出，一次换辊时间仅为20min.

You don"t need to replace the whole fast roller roller way for mining crane， trolley and swing roller tr**ersing trolley with the guide beam is installed on the bearing seat of rolling mill， roll changing， guide and beam with roll set pulled from the housing window， a roll change time is only 20min.
