    摘要： A method for determining a shape of a shift roll for a rolling mill, includes the steps of determining a necessary control amount distribution nulli for a plate crown with respect to plate widths, based on a distribution of the number of plates rolled by a target rolling mill with respect to plate widths, and providing a maximum radius difference yA0 of the shift roll. The method further includes the steps of preliminarily determining a line yi of a roll radius distribution with respect to plate widths, based on the necessary control amount distribution nulli and the maximum radius difference yA0, shifting the line yi of the roll radius distribution by a maximum roll shift to obtain a distribution nullyBi of a roll gap change amount with respect to plate widths under the maximum roll shift, and smoothing sharp local changing part of the distribution nullyBi of the roll gap change amount.

    摘要： The invention relates to a roll stand for hot-rolling or cold-rolling metallic strips. Said roll stand comprises back-up rolls and work rolls (2,3; 4,5) which are respectively positioned in chocks (6; 7) in a rotating manner. Each chock (6; 7) can be displaced on two sides in guiding devices (8) of the column frame (9) for adjusting the roll gap (10) and can be additionally displaced on at least one side for adjusting the play, by means of horizontal piston cylinder units (11) arranged in the column frame (9). The aim of the invention is to completely eliminate the play in the vertical guiding device (8) of the work roll chocks (6; 7) during the rolling. To this end, the chocks which are guided on at least one side of the column (9a) by means of the piston cylinder unit (11) arranged in the column frame (9) and by means of one respective support element (14) which is arranged on the front side of the piston (11a), can be pressed against the other side of the column (9b) and the guiding device (8) thereof without play when the vertical roll positioning drive is stopped, and can be released when the vertical roll positioning drive is switched on.

    摘要： A roll shifting cylinder 14 is driven to pivot a lever arm 12, thereby shifting a work roll 1 via a thrust bearing 15. A control unit 27 performs auto-positioning control, based on a shift amount performance value of the thrust bearing 15 detected by a shift amount detection sensor 16, so as to obtain a target roll shift position. A constant clearance amount is maintained between an end surface of the work roll 1 and the thrust bearing 15 during a rolling operation, and a chockless mill is effectively used as a work roll shift mill.

    摘要： A rolling mill having a plurality of roll units, a rolling-reduction adjusting device of an eccentric-cartridge type, and a roll-alignment adjusting device, all mounted on its housing. The housing is split into freely separable and joinable first and second housing segments. The housing segments have semicircular bearing-holder segments formed in their joint surfaces. The shafts of the roll units are held between the first and second housing segments by being journaled in eccentric cartridges which are fitted in the bearing holders consisting of the semicircular bearing-holder segments. The roll-alignment adjusting device includes adjusting mechanisms and chucks to connect the shaft ends of the roll units to the adjusting rods of the adjusting mechanisms. Each adjusting mechanism further comprises (i) an outer nut which is fixed to the housing and has internal threads, (ii) a middle nut which has internal and external threads, the external threads engaging the internal threads of the outer nut, and is rotated externally, and (iii) an adjusting rod which has external threads to engage the internal threads of the middle nut. A first thread joint is defined by the internal threads of the outer nut. An external thread is defined by the middle nut and the second thread joint by the internal threads of the middle nut and the external threads of the adjusting rod. The first and second thread joints are each given a thread of the opposite hand and a different pitch.

    摘要： A pair of rotary die cylinders each removably mountable in a die stand by a pair of opposed arbor assemblies each with a separate spindle journaled in a separate carrier block and having a nose drawable into engagement with complementary recesses in opposed ends of the die cylinder in coaxial alignment with the axis of the die cylinder. The noses of the spindles are removably engaged in the recess by a drawbar extending through each cylinder. The carrier blocks are removably slidably received in slots in a pair of spaced apart uprights of the die stand.
