摘要： A continuous mill has a plurality of passes arranged in series and formed by work rolls which are mounted on shafts secured to common chocks accommodated in housings.The chocks provided in the mill are equal in number to the workrolls forming a pass. Each of the chocks has two sides converging at an angle, and the shafts carrying the workrolls are cantilevered to each of said sides. The shafts secured to one side are offset relative to the shafts secured to another side so that the adjacent passes are spaced in closest possible proximity with one another; the angle between the sides of each chocks being equal to the divergence angle of the adjacent passes.

摘要： The device proposed herein incorporates the following components located on both sides of the roll mill stand: hydraulic dynamometers for absorbing the rolling force; hydraulic cylinders for creating and exerting the adjusting force; and valves for oil pressure control in the hydraulic cylinder interior. The hydraulic dynamometers are situated between the supports of one of the rolls and the roll mill stand housing and the hydraulic cylinders are interposed between the supports of the other roll and the roll mill stand housing.The interior spaces of said cylinder and the dynamometer communicate with pumping units that deliver oil thereto so as to build up a pressure in the spaces which is in excess of the rolling force. The valves regulate the pressure effective in the hydraulic cylinder interior in direct proportion to the rolling force and the deforming force of the elastic members of the device.

摘要： The present invention relates to methods of rolling metal articles and can be used to advantage in rolling sheet steel. This method envisages the rotation of drive and driven work rolls in opposite directions at a higher and a lower peripheral speeds, respectively. The chosen ratio between the peripheral speeds of the work rolls is less than the elongation of the article so that thereby the specified unit tension applied to the article at the exit section thereof is provided for with reference to the ultimate strength of the metal emerging from the rolls. This is conducive to increasing the maximum elongation of the article and reducing the roll force by a considerable amount with the constriction of the article in breadth at the same time.

摘要： Proposed herein is a method of controlling the thickness of strip stock being rolled between rolls mounted in the roll stand of a mill. An adjusting force is developed to move the supports of one of the rolls, this force exceeding the rolling force and being directed oppositely thereto. Another force prevents the supports of the rolls from moving towards each other and balances the difference between the adjusting force and the rolling force. The factor of proportionality between the movement of the roll supports and the balancing force is in a definite predetermined ratio with the mill stand stiffness factor. The adjusting force is changed in the course of strip stock deformation to compensate for the roll gap variation in proportion to the rolling force according to the following formula:R=k.sub.2 P,whereR denotes the adjusting force causing the roll supports to move;P denotes the rolling force; andk.sub.2 can be found from the equation:k.sub.2 =(k.sub.1 /k)+1;where k.sub.1 denotes the factor of proportionality between the amount of movement of the roll supports and the balancing force; and k denotes the stiffness factor of the roll mill stand.

摘要： A method of rolling metal billets in a single pass comprises the steps of reducing a billet by workrolls and alternating each reduction cycle of the billet being worked with axial feed thereof through a step of rolling. As the billet is worked by the workrolls a transitional section is formed thereon as a deformation cone having a length along the axis of the billet substantially greater than the corresponding length of the deformation zone induced in the billet by each workroll at each given moment. The mill for carrying out this method comprises a frame having guides running in parallel with the axis of the billet being worked and mounting a roll housing geared to the mill drive to reciprocate the roll housing inside said guides in the course of rolling. The roll housing accommodates at least four variable-radius workrolls having their geometrical axes of rotation extended in one plane perpendicular to the axis of the billet being worked, the rotation of the workrolls about said axes being effected in the course of rolling positively and in synchronism with the reciprocations of the housing. The mill is also provided with a feeder for axially feeding the billet to the workrolls, mounted on the frame on the side of the billet entry to the workrolls and geared to the mill drive.

摘要： The present invention relates to plastic working of metals and the reducing of a workpiece along its axis by a pair of shaped rolls with formation in the workpiece of a transitional length whose cross section gradually changes from a starting one to several cross sections of finished bars interconnected by webs. The reduction of the workpiece is alternated with its axial displacement through one feed step, whereas at the end of a transitional length adjacent bars are displaced one with respect to another in opposite directions perpendicularly to webs so as to separate the bars. Mill rolls used with the method have several grooves of a variable cross section which form passes for rolling bars. The profile of each groove in transversal (with respect to mill roll axis of rotation) cross section is formed of two mutually conjugated arcs successively coming into contact with the workpiece. The grooves have an arc for reducing the workpiece and an arc for dividing bars one from another. The centers of curvature of the arcs are located at different eccentricities with respect to the mill roll axis of rotation, with the directions of eccentricity alternating in adjacent grooves.
