    • An installation for replacing live rolls in a rolling mill, comprising a drum which rotates about an axis parallel to the axes of the rolls in the tightening plane passing through these axes. The drum comprises at least two compartments, each symmetrical with respect to a median plane passing through the axis of rotation, and which can be placed, alternately, by rotating the drum, in a roll replacement position in front of the working zone of the mill stand. Each compartment has two pairs of guide rails which, in the roll replacement position of the corresponding compartment, are aligned, respectively, with two pairs of fixed rails in the stand. One of the compartments is vacant, while each of the other compartments holds in store a pair of live rolls, which have chocks bearing on the corresponding rails of the compartment. The drum is associated with a mechanism for transferring live rolls into the vacant compartment of the drum and replacement rolls into the working position in the stand.
    • 一种用于在轧机中更换活动辊的装置,包括滚筒,所述滚筒围绕平行于穿过这些轴线的紧固平面中的辊的轴线旋转。 滚筒包括至少两个隔室,每个隔间相对于通过旋转轴线的中间平面对称,并且可以通过在滚筒的工作区域前方的辊更换位置中旋转滚筒来交替放置 站。 每个隔间具有两对导轨,在对应的隔间的辊更换位置分别与支架中的两对固定导轨对准。 其中一个隔间是空的,而每个其他隔间都存放着一对活动辊,它们具有轴承在隔室相应的导轨上的轴承座。 滚筒与用于将活辊转移到滚筒的空闲隔间中的机构相关联,更换辊进入支架的工作位置。

    • Cleaning apparatus for a roll placed in contact with a metal strap moving longitudinally in an installation comprising a set of rotary-mounted superposed rolls between two stands of a fixed supporting cage and comprising at least one wiping tool (4) parallel to the axes of the rolls, a device (3) supporting the wiping tool mounted slidingly on straight guide rollers (24, 24') provided on a cradle (2) pivotably mounted on both stands (11) of the cage (1) around a pivot axis (20) parallel to the axes of the rolls. The cradle (2) comprises two spaced parallel flanges (21) linked rigidly by a crossbeam (22) and rotatably mounted, respectively, on two bearings fixed, respectively, on both stands (11) of the cage (10) and placed so that the cradle (2) can pivot between a working position in which the sliding plane of the supporting device (3) is oriented to the roll (1) to be cleaned and a maintenance position in which the sliding plane is removed from the roll ( 1) and the supporting device (3) is placed along both stands (11) of the cage (10), slightly extending in from the roll (1) and is placed along both stands (11) outside the cage, the supporting device extending in cantilever, in forward position, beyond the guide rollers (24, 24') to its front section (36) carrying the wiping tool (4) is located close to the roll (1) and the front section (36) is brought back of the cradle (2) in the rearward position of the frame (3) to allow the cradle (2) to pivot to the maintenance position along the stands (11) of the cage.
    • 一种与在金属带上接触的辊的清洁装置,该金属带在包括一组固定支撑笼的两个支架之间的一组旋转安装的重叠辊的装置中纵向移动,并且包括至少一个平行于 滚筒,支撑擦拭工具的装置(3),其滑动地安装在可枢转地安装在保持架(1)的两个支架(11)上的支架(2)上的直线导辊(24,24')上,绕枢转轴线(20,24) )平行于辊的轴线。 托架(2)包括两个间隔开的平行凸缘(21),其通过横梁(22)刚性地连接并分别可旋转地安装在分别固定在保持架(10)的两个支架(11)上的两个轴承上, 托架(2)可以在支撑装置(3)的滑动平面定向到待清洁的辊(1)的工作位置和从辊(1)移除滑动面的维护位置之间枢转 )和支撑装置(3)沿着保持架(10)的两个支架(11)放置,从辊(1)稍微延伸并且沿着保持架外部的两个支架(11)放置,支撑装置延伸到 悬臂在向前位置超过导辊(24,24')到其携带擦拭工具(4)的前部(36)位于靠近辊(1)的位置,并且前部(36)被带回 所述支架(2)位于所述框架(3)的向后位置,以允许所述支架(2)沿着所述第二支架枢转到所述维护位置 (11)。
