    摘要： In an apparatus for fixing a roll ring 4 on a roll shaft 2 mounted in two parallel roll stands 1a, 1b on both sides of the roll ring, by means of a tensioning means 18 and an axially tensionable conical sleeve 8 a radial tension is generated in the roll ring 4. In addition, the conical sleeve 8 carries the roll shaft bearing 3a.To enable the axial and radial tensioning of the roll ring 4 to be adjusted simply and accurately in spite of the additional roll shaft bearing 3a, the tensioning means 18 acts on the one hand on the conical sleeve 8 via a first thrust transmitting means passing through the roll stand 1a and on the other hand on the roll ring 4 clamped between two thrust rings 22, 23 via a second thrust transmitting means passing through the roll stand, one of the two thrust transmitting means also receiving the roll shaft bearing 3a.

    摘要： A roll changing apparatus for rolling mills which is adapted for use in the manufacture of seamless steel pipes. The apparatus comprises a pair of sliding bases each mounted on a base block and movable parallel to each other, a plurality of roll carriages each containing a set of rolls, and means for moving the roll carriages, wherein two or more of the roll carriages are placed on each of the sliding bases and at least one of the roll carriages on each sliding base is moved forward to form a roll mill. When the roll carriages are to be changed, the forwardly moved roll carriages are moved back onto the sliding bases and then the other roll carriages are moved forward, thus automatically accomplishing the roll carriage changing in a short period of time.

    摘要： A rolling mill having a roll stand with back-up rolls and two cylindrical work rolls. The work rolls have roll-pass grooves associated in pairs with different roll-pass areas. The driving mechanism of the rolling mill is coupled to the back-up rolls which exercise constant pressure on the work rolls during rolling so that these are in hard mutual contact and rotate with the back-up rolls. The work rolls are axially displaceable in the roll stands between the back-up rolls when the latter are open so that a desired roll-pass groove can be positioned with its center line coinciding with the central plane of the rolling mill.

    摘要： A roll stand for horizontally journalled contoured rolls is constructed to have two windows, through one of these windows driving engagement is made to the rolls and through the other one two subassemblies may be inserted or removed together from the stand. Each subassembly includes a pair of mounting blocks, a shaft and a roll on the shaft. The two subassemblies are axially locked together and/or independently to the stand, while one rests on the other or is suspended from adjustment spindles. The two subassemblies are removed from the stand together by a lifting fork, requiring only that the connection to the stand be released but leaving the two subassemblies interconnected.

    摘要： A universal cassette type stand for a continuous rolling line which can be converted from a universal beam stand having two horizontal rolls and two vertical rolls into a stand having two horizontal rolls for rolling structural shapes. Each horizontal and vertical roll includes two hydraulic tightening jacks each associated with a different chock. Each jack is provided with a servo-valve, a position sensor, and a pressure probe. The supply of each jack is servo-controlled by a regulation loop where the measurement of the tightening is transformed into a position reference depending on the modulus of either the lower or upper part or sides of the stand. The regulation or control loop is such that one of several alternatives for rolling the beam to a desired mode can be accomplished. For instance, the loop can be set up to obtain (1) a constant web, constant flange thickness while maintaining symmetry of the web relative to the flange, or (2) the loop can be set up to obtain a ratio thickness of web relative to the flanges while still maintaining symmetry of the web relative to the flange.

    摘要翻译： 一种用于连续轧制线的通用盒式支架，其可以从具有两个水平辊和两个垂直辊的通用梁架转换成具有两个用于滚动结构形状的水平辊的支架。 每个水平和垂直辊包括两个液压拧紧千斤顶，每个与不同的轴承座相关联。 每个千斤顶配有伺服阀，位置传感器和压力探头。 每个千斤顶的供应通过调节回路进行伺服控制，其中根据支架的下部或上部或两侧的模量将紧固度的测量转换为位置参考。 调节或控制回路使得可以实现将光束滚动到期望模式的几种替代方案之一。 例如，可以设置回路以获得（1）恒定的腹板，恒定的凸缘厚度，同时保持腹板相对于凸缘的对称性，或（2）可以设置回路以获得腹板相对的比例厚度 同时仍然保持幅材相对于凸缘的对称性。

    摘要： A roll change rig for a four-high plate mill stand consists of a beam which can be driven towards and away from the stand and which has two separate couplings, one for connection to a work roll and the other for connection to the lower back-up roll. There are separate rolls for the lower work roll and lower backup roll, on which the respective roll may be moved through the stand and into a roll change area, by operation of the beam. If the stand has hydraulic roll gap adjustment, the rig includes a trolley which can run on the back-up roll rails, which is driven by the roll change beam, and which carries lifting means for lifting a piston and cylinder assembly from the mill.
