    CPC classification number: B21B39/12

    Abstract: Roller table apparatus (200; 300) for transporting a metallic product (P) to or from a mill stand, includes: first and second rolls (202a, 202b; 302a, 302b), outboard ends of the rolls are supported by respective outboard bearings and inboard ends of the rolls are supported by respective inboard bearings, such that each of the rolls is rotatable about its longitudinal axis (X1, X2); and at least one adjuster (216; 316a, 316b), movable in use to displace at least one end of the rolls or the respective bearings of the roll so as to adjust an angle (α) of inclination of each of the longitudinal axes of the rolls with respect to a datum (D), thereby to adjust a pass-line height (h1, h2) of the product relative to the datum.

    IPC: B21B38/10

    Abstract: A method of controlling a roll gap between first and second work rolls (102, 104) that includes defining a plurality of work surface locations spaced apart along the first work roll (102) in the longitudinal direction; obtaining a radius of the work surface (102a) of the first work roll (102) at each of the work surface locations; based on the radii of the work surface locations, obtaining a longitudinal profile of the work surface (102a); based on the longitudinal profile, tilting the first work roll (102) relative to the second work roll (104) in the common plane in order to reduce a difference in the average size of the gap either side of a centerline (CL), which bisects the longitudinal axes of the first and second work rolls (102, 104).

    Abstract: A cyclonic adaptor for fitting to a gravity-based dustcatcher (100) for a metallurgical processing plant: at least one input pipe (203), and a cyclone chamber (205) having a curved inner surface for guiding a gas flow within the interior of the cyclone chamber in a cyclonic manner. The cyclone chamber (205) having an exit in fluid communication with an outlet of the dustcatcher in use, wherein the at least one input pipe (203) has a first end in fluid communication with an inlet (104) of the dustcatcher (100) in use and the inlet pipe is adapted to receive exhaust gas containing solid particles from a metallurgical processing plant from the inlet (104) of the dustcatcher (100), and extends from the first end to a second end positioned in fluid communication with the interior of the cyclone chamber (205), wherein the second end is arranged to direct the exhaust gas in an at least primarily tangential direction with respect to the curved inner surface of the cyclone chamber such that the exhaust gas entering the cyclone chamber (205) flows in a cyclonic manner in order to remove solid particles from the exhaust gas before flowing through the exit, and wherein the cyclone chamber (205) is adapted to be housed within an interior volume of the dustcatcher (100).

    Abstract: A bearing system includes: a rotatable shaft, a circumferential channel in the shaft with an axially extending profile surface at least part of which is inclined relative to the shaft axis; a bearing, around the shaft in use; a split ring in the circumferential channel in contact with the inclined profile surface, the split ring includes a first part having an outer diameter, and a second part having a greater outer diameter than the first part to provide a thrust surface; a collar, including an internal bore to accommodate the first part of the split ring in use; and a bearing locator for exerting an axial locating force between the split ring and the bearing to locate the bearing on the shaft. An axial thrust load exerted on the split ring by the shaft is transmitted to the collar by the thrust surface, and the split ring is urged along the inclined profile surface so as to produce a radial load on the split ring which is resisted by the collar.

    Abstract: A variable rake shear comprises a housing (8), a first blade (1) mounted in a first blade mounting (4), a second blade (2) mounted in a second blade mounting (3); and a control device (5) to control movement of one blade mounting to shear the material. Each blade mounting is movable in at least one dimension relative to the housing. One blade is an active blade (1) and the other blade is a passive blade (2). A rake adjustment mechanism (6a, 6b) for at least one of the mountings (3, 4) and the mounting (4) for the active blade (1) has a torque tube linkage mechanism (10, 11, 12).
