Patent number: 4047985Abstract: The disclosure pertains to an arrangement for cooling a heated workpiece, such as, strip or slab as it issues from a rolling mill or continuous slab caster. The longitudinally moving workpiece is caused to pass between a number of coolant discharge headers arranged above and below the workpiece in which, during its cooling, the coolig rates of the upper and lower surfaces of the workpiece differ. The effective discharge of the headers is varied to equalize the cooling rates of the upper and lower surfaces of the workpiece to symmetrically cool the workpiece.Type: GrantFiled: February 9, 1976Date of Patent: September 13, 1977Assignee: Wean United, Inc.Inventor: Joseph Irwin Greenberger

Patent number: 4037444Abstract: A system for incremently and continuously feeding tubes between dies during a prescribed angle of rotation of a crank assembly in a cold pilger mill. As a main motor drives the crank assembly, a servo-motor, receiving a signal from a digital control unit, which receives a signal from a pulsating encoder associated with the main drive, operates to incremently advance a carriage and shell a controlled predetermined distance between the dies. A reversal of the servo-motor returns the carriage to the initial position in preparation to advance another shell.Type: GrantFiled: January 10, 1977Date of Patent: July 26, 1977Assignee: Wean United, Inc.Inventors: Harry Calhoon Ledebur, Floyd William Diehl, Jr.

Patent number: 4019846Abstract: An arrangement for controlling the temperature of an arbor-sleeve type roll employed in a rolling process such as in a briquetting machine by transporting temperature control medium to the extremities of the working surface of a removable sleeve by providing in the arbor a system of passageways extending radially and terminating at a point beneath the outer surface of the arbor and by providing in the sleeve a system of interconnecting axially extending passageways. Both of these systems are joined by manifold ring assemblies mounted externally of the roll and which include an expandable bellows which compensate for thermal variation of the roll during the briquetting process. Two other rings, also mounted externally, are connected to the opposite sides of the arbor and sleeve, thereby preventing relative movement between the arbor and sleeve and still permitting the quick removal and replacement of the sleeve.Type: GrantFiled: September 30, 1976Date of Patent: April 26, 1977Assignee: Wean United, Inc.Inventor: Joseph Irwin Greenberger
-
Patent number: 4005595Abstract: The disclosure relates to a workpiece feed apparatus for cold pilger rolling mills having at least one feed spindle for at least one feed carriage, and having a feed transmission which is connected to the main drive and comprises two branches or lines of drive, of which the first line of drive is connected with a gear wheel secured on the feed spindle for producing a continuous rotational movement of the feed spindle, and the second line of drive is connected by way of an intermittently moved lever with the feed spindle for the purpose of producing an intermittent axial movement of the feed spindle.Type: GrantFiled: September 26, 1975Date of Patent: February 1, 1977Assignee: Wean United, Inc.Inventors: Josef Gerretz, Klaus Rehag
-
Patent number: 4004459Abstract: A strip contacting device used between stands of a rolling mill for simultaneously performing combined modes of operation, such as a shapemeter/looper or a shapemeter/tensiometer. It consists of a frame with a pivotal arm connected to a piston cylinder assembly, whereby a desired mode can be carried out by using a shapemeter roller and allowing the arm to either float or assume a fixed position relative to the passline of the mill.Type: GrantFiled: April 14, 1976Date of Patent: January 25, 1977Assignee: Wean United, Inc.Inventor: Joseph Irwin Greenberger
-
Patent number: 3988916Abstract: The disclosure of this invention pertains to a strip guiding mechanism for use with a rotating mandrel around which strip is wound into a coil. The guiding mechanism consists of two carriages movable in opposite radial directions towards and away from the mandrel. The carriages are mounted on a common frame that is movable in an axial direction of the mandrel to a position in front thereof after the coil has been started and then the frame is rotated to remove the carriage from the front of the mandrel to allow on completion the removal of the coil from the mandrel.Type: GrantFiled: March 17, 1975Date of Patent: November 2, 1976Assignee: Wean United, Inc.Inventor: William Stone McGeeney

Patent number: 3975938Abstract: The disclosure concerns a roll changing device for roll stands of a rolling mill or the like having a pair of working rolls and backing rolls assigned to each working roll in which the roll pairs, including their component bearing parts, can be moved as separate units into and out of the windows of the housings of the mill. A piston cylinder assembly provided for this purpose is arranged in front of the understructure for the support member of the lower backing roll.Type: GrantFiled: December 5, 1975Date of Patent: August 24, 1976Assignee: Schloemann-Siemag AktiengesellschaftInventors: Arno Schmidt, Rudolf Mueller

Patent number: 3970191Abstract: Transfer apparatus for a workpiece such as a metal slab, bloom or coil of metal strip comprises a carriage supported on a substantially horizontal beam. The beam is displaceable in the direction of its length and the ends of a flexible cable are connected to opposite ends of the carriage with a reach of the cable extending substantially parallel to the length of the beam. An intermediate point of the cable is firmly anchored so that displacement of the beam causes the carriage to be displaced along the beam as well as its movement with the beam. The beam can also be raised and lowered.Type: GrantFiled: February 3, 1975Date of Patent: July 20, 1976Assignee: Wean United, Inc.Inventors: Derek Oldfield, Dennis Postlethwaite

Patent number: 3961510Abstract: The disclosure of this application relates to a looper device employed to impose a constant tension on a strip as it passes between the stands of a tandem rolling mill. The looper is operated by an hydraulic actuator which is controlled by a computer controlled hydraulic servosystem. The computer is fed a signal of the position of the looper and calculates the required pressure difference across the actuator for a desired tension.Type: GrantFiled: July 11, 1975Date of Patent: June 8, 1976Assignee: Wean United, Inc.Inventor: Daniel Charles Kovacs

Patent number: 3946587Abstract: A rolling mill stand for hot or cold rolling rod and flats has a C-shaped housing and a bolt connecting the protruding ends of the housing. The work rolls are mounted in cantilever fashion and are carried in chocks which are restrained by the housing. The chocks are pivoted to the housing about pivot pins, the axes of which are parallel to the axes of the work rolls and are displaced from the plane through the roll axes. Pivoting of the chocks about the pivot pins in order to vary the separation of the work rolls does not affect the shape of the roll gap.Type: GrantFiled: December 4, 1974Date of Patent: March 30, 1976Assignee: Davy-Loewy Ltd.Inventor: Jack Maltby
