Definitions

  • My invention relates to the rolling of metal and, particularly, to the hot rolling of strip and a mill therefor.
  • I provide side guides on both sides of the 5 mill and operate the guides successively to provide a parallel guiding throat on the entering side of the mill and a tapered guiding throat on the' other side of the mill.
  • the conditions of the guides on the two sides of the mills are reversed automatically by a change in the direction of the movement of the piece.
  • Means are provided for adjusting the guides initially to cooperate with materialof any desired width within the range of a particular construction.
  • My invention also includes means for flattening or leveling the leading end of the piece prior to engagement with the furnace coiler.
  • This means takes the form of a series of flattening rolls adjacent the furnace mouth. In passing through the rolls, the end of the strip is straightened or flattened so that proper engagement with the furnace coiler is insured practically without exception.
  • I also provide pinch rolls for feeding the material toward the mill and, after passing through the mill, toward the coilers, between passes,
  • pinch rolls are automatically raised when the strip has been properly started. They are also withdrawn when the material being rolled is handled back and forth through the mill in the flat without coiling between passes.
  • Figure 1 is a horizontal section through a mill having my invention incorporated therein showing parts in plan;
  • Figure 1A is a partial, sectional view similar to Figure 1 showing a slightly modified form of construction
  • FIG. 2 is a partial side elevation with'the mill housings removed for the sake of clearness
  • Figure 3 is a partial sectional view along the line IIIII[ of Figure 2, showing parts in elevation;
  • Figure 4 is a partial, vertical section through the coiling furnace showing other parts in elevation to a slightly enlarged scale
  • Figure 5 is a side elevation similar to Figure 4 showing a modified form of construction embodying pinch rolls particularly adapted for automatic operation, as well as flattening rolls;
  • Figure 6 is a vertical, sectional view along the line VI-VI of Figure 5 showing parts in elevation;
  • Figure 7 is a partial, sectional view along the line VII.VII of Figure 5;
  • Figure 8 is a schematic diagram of the automatic control system for the apparatus of Figures 5 through '7;
  • Figure 9 is a similar view of the system for controlling the guides of Figures 1 through 3.
  • a mill l0 comprises housings H having windows l2 for receiving bearing chucks adjustably positioned therein. Backing rolls l4 and working rolls l5 are journaled in the chucks, the rolls preferably having anti-friction bearings, not shown.
  • the housings H are connected by transoms l6.
  • Auxiliary housings l8 are positioned on opposite sides of the mill.
  • Roll tables l9 extend between the housings l8 for conveying material to and from the mill rolls.
  • therein are positioned at a convenient distance from the mill.
  • Tilting guides 22 are provided on the roll tables IQ for diverting material advancing through the mill from a horithat in which the strip moves. The remainder I of the strip is then drawn around a scale-breaking roll 24 at the edge of the furnace mouth and wound up on the coiler.
  • a base 25 is carried between each of the auxiliary housings l8.
  • Bottom guides 26 are pivotally supported on the bases 25 at 21.
  • the guides 26 are also supported by flat seats 28.
  • Top guides 28 are pivoted at 30 to the transoms i6 and are suspended from angle bars 3
  • the inner ends of the guides 26 and 29 are shaped to conform closely to and are actually in contact with the work rolls to effect a stripping action in case the piece tends to follow around the periphery of one or the other of the rolls.
  • Screw shafts 33 are slidably mounted in the housing l8 parallel to the axes of the mill rolls.
  • Side guides 34 are supported on the screw shafts 33 by hinged joints 35.
  • the guides 34 have a plane inner surface 36 with recesses into which anti-friction rolls 3'! are let.
  • the mill ends of the guides extend to a point closely adjacent the rolls, as shown in Figures 1 and 2.
  • the outer ends of the guides are pivotally supported on nuts 38 traveling on a screw shaft 39 journaled in the side frames of the table IS.
  • the ends of the screw shaft 39 are oppositely threaded so that on rotation of the shaft, the outer ends of the guides are moved toward or away from the center line of the table I9.
  • my invention provides side guides which may be disposed in parallel relation, as shown on the left-hand side of the mill in Figure 1; or in angular relation, as shown on the right-hand side of the mill in Figure 1, for the purposes, respectively, of definitely and positively guiding the leading end of an advancing strip into the rolls at the proper angle thereto, and providing a tapering throat for receiving the end of the piece as it emerges from the mill.
  • side guides which may be disposed in parallel relation, as shown on the left-hand side of the mill in Figure 1; or in angular relation, as shown on the right-hand side of the mill in Figure 1, for the purposes, respectively, of definitely and positively guiding the leading end of an advancing strip into the rolls at the proper angle thereto, and providing a tapering throat for receiving the end of the piece as it emerges from the mill.
  • the outer ends of the guides may be adjusted toward or away from each other through the shaft 39, as already described. This adjustment is effected by a hand wheel 46 having a pinion 4
  • gear gamma cases 46 attached to the housings I. enclose gearwheels 46 having their bores threaded for engagement with the shafts 33, and pinions 41 keyed to shafts 48.
  • Hand wheels 48 permit manual adjustment of the screw shafts 33.
  • These shafts are normally driven from extensions 50 of the shaft of one of the rolls 5
  • The'rolls of the table are driven from a line shaft 52 through the usual bevel gears by a reversing motor, not shown.
  • friction clutches 53 and law clutches 64 having operating levers 55.
  • the purpose of the friction clutches is to permit the rotation of the shaft 48 to be arrested after a predetermined movement thereof without stopping the operation ofthe roll 5
  • the jaw clutches 54 permit the shafts 33 to be freed from the table drive while being manually adjusted.
  • the friction clutches 53 have detents 56 thereon cooperating with stops 5'! on the housing? l8 to limit rotation of the shaft 48 to the desired extent. After the detents engage the stops, the adjustment of the shafts 33 ceases but the roll 5
  • the inner ends of the guides 34 will be spread to form a tapering throat or moved together to parallel position with the reversal of the drive for the rolls of table IS.
  • the detents and'stops controlling the amount of rotation of the friction clutches will determine the amount of movement imparted to the inner ends of the guides and may, if desired, bemade adjustable.
  • the guide-operating mechanism is designed so that the guides will be spread at the mill end when the table rolls are driven in such a direction as to' move material away from the mill.
  • the guides on the opposite side of the mill will be actuated to parallel position. the material advancing toward the mill is definitely and positively alined at right angles to the plane containing the axes of the mill rolls.
  • housings 66 supported on side members of the roll table l3 have bearing chucks 6
  • Rolls 63 and 64 journaled in the chucks 6
  • a roll 66 also journaled in the chuck 6
  • the chucks 68 are actuated by pneumatic cylinders 63.
  • the rolls 63 and 65 may be driven and when the former is lowered into engagement with the latter, they serve as pinch rolls to feed the strip toward the mill from the coiler 2
  • the chucks 6i are preferably raised and the rolls 83, 64 and 66 lifted oi? the strip.
  • the chucks 88 of the rolls 61 are preferably lifted at the same time as the chucks -6I. In its normal lower position, however, the roll B'Iis effective to assist in flattening or leveling the leading'end of the material in its passage from the mill to the coiler.
  • the pinch rolls 63 are lowered, of course, at this time.
  • Figure 1A illustrates a modified form of actuating mechanism for the guides 36.
  • This means takes the form of pistons 10 reciprocable in cylinders II by means of fluid pressure, hydraulic or pneumatic, supplied thereto.
  • the pistons I have piston rods I2 attached thereto corresponding to the screw shafts 33 and functioning in the same way, under the influence of fluid pressure admitted to either side of the cylinders H for actuating the guides.
  • a modified form of construction of the auxiliary rolls for feeding and flattening the strip is shown in Figures through '7.
  • a roll table I3 has side frame castings I4. Housings 15 are attached to the castings I4 and have windows 16 therein in which bearing chucks 11 are slidable. Cylinders 18 formed in the upper part of the housings I5 have pistons 19 reciprocating therein. Piston rods 80 attached to the pistons I0 are threaded.
  • Piston rods 80 extend outwardly through the upper end of the cylinders I8 and are connected by cross beams 8
  • the piston rods of the cylinders 82 have separable, abutting engagement with bolts 8Ia. It will be apparent that the cylinders I9 and 82 provide independent means ,for lifting the chucks 11 through a long stroke and a short stroke, respectively. The object of this arrangement will become apparent as the description proceeds.
  • An equalizing shaft 84 extends betweenthe housings I5 and is journaled therein.
  • Cranks 85 keyed to the shaft 84 carry trunnions 86 in slidable bearings blocks 81.
  • the trunnions 86 are th aded into the chucks 11, as best shown in Figure 6. effect simultaneous and equal movement of both bearing chucks and prevents binding of the reciprocating mechanism.
  • a top pinch roll 88 is journaled in the chucks TI for cooperation with a bottom pinch roll 89, which-may conveniently be one of the rollers of the table 13.
  • Flattening rolls 90 and 9I are also journaled in the chucks TI.
  • the roll 9I cooperates with a roll of the table 13.
  • a roll 92 is journaled in chucks 93 slidable vertically in the base
  • the equalizing shaft obviously serves to portions of the housings I6. Cylinders and pistons 94, bell crank linkage 95 and struts 98 are provided, as shown in Figure 5 to effect vertical movement of the chucks 93 for a purpose which will appear later.
  • the roll 90 is journaled inchucks 91'secured to the chucks H.
  • a contact-actuating rod 98 is threaded into a projection 99 from one of the chucks 98.
  • the rod 98 also passes through guides I00 projecting from one of the chucks 91.
  • the rod 98 controls the engagement of a moving contact II" with a fixed I contact I02 on one of the chucks 11 for a purpose which will presently appear.
  • the chucks 93 are normally lowered so that contact IOI engages contact I02. These contacts control a circuit for stopping the main mill motor in case of breakage of the strip.
  • rest on .the strip and are spaced thereby from the rolls 89 and 92.
  • fluid is admitted to the cylinders 94 to cause the chucks 93 to be raised until the roll 92 engages the lower surface of the strip.
  • the rolling operation then proceeds. If breakage of the strip should occur, the continuing fluid pressure in the cylinders 94 causes the chucks 93 to rise until theroll 92 actually engages the roll 90. This causes the rod 98 to move upwardly and lift contact IOI out of engagement with contact I02. Separation of these contacts, through suitable auxiliary equipment, causes stoppage of the main mill motor.
  • the cylinders 19 and 82 are automatically controlled to cause the pinch rolls 88 and 89 to engage the material at certain times and to release it at other times.
  • the pinch rolls 88 In rolling a slab into strip on the mill I0, it is desirable that the pinch rolls 88 be withdrawn as long as the slab being reduced has suiflcient rigidity to permit it to be fed back and forth to and from the mill by the friction .of the table rolls.
  • the pinch rolls are advanced to assist in threading the strip through the mill at the beginning of each pass. While both ends of the strip actually pass through the mill, the pinch roll motors are so controlled that neither end of the strip is disengaged from the pinch rolls on both sides of the mill. At least one end of the strip is always engaged by at least one set of pinch rolls. It is by these pinch rolls that the strip is then fed back to the mill for the next pass. On the exit side of the mill, the pinch rolls assist in delivering the leading end of the strip into the coiler by pushing it up the guide 22.
  • FIG 8 the work rolls of the mill are indicated by the same numeral as in Figures 1 and 2.
  • a motor I03 is provided for driving the mill and the power of the motor may be applied directly to the work rolls I5 or to the backing rolls I4.
  • the motor I03 may be controlled by any suitable control system.
  • I have only illustrated a control panel I04 having incoming power leads, outgoing motor leads, and outgoing control leads extending to a controller I05.
  • the panel I04 of course, will be provided with suitable relays and contactors effective under the control of the controller I05 to cause starting of the motor I 03.
  • the panel I08 alsohas a relay I08 effective when deenergized to cause stopping of the motor.
  • the controller I05 obviously, is effective on being shifted manually in one direction or the other, to cause operation of the motor I03 to drive the mill rolls I5 and thus move the strip through the mill in the desired direction.
  • the supply of fluid to the cylinders 18, 82 and 98 is controlled by a master valve I01 and auxiliary valves I08 and I09.
  • the valve I01 has operating magnets H0 and III and the valve is of such character that it remains in the position to which it was last operated until positively actuated therefrom.
  • the valves I08-and I09 have operating magnets H2 and H8. The arrangement of these valves and their operating magnets is such that they remain in the illustrated position until the magnets are energized, and return to the illustrated position when the magnets are deenergized.
  • the valve I01 is controlled by a limit switch II4 operated by any convenient means, in accordance with the position of the mill screwdowns which determine the thickness of the pass between the rolls and the material itself after passing through the mill.
  • a limit switch II4 operated by any convenient means, in accordance with the position of the mill screwdowns which determine the thickness of the pass between the rolls and the material itself after passing through the mill.
  • the limit switch Ill closes its lower contacts to energize the magnet III and move the valve I01 so that fluid under pressure is supplied from a reservoir II5 through suitable piping, to the cylinders I8 on both sides of the mill.
  • the pistons 19 are thereby actuated full stroketo withdraw the upper pinch roll 80 and provide ample free space for the passage back and forth to and from the mill of the slab in the initial stages of its reduction to strip.
  • the limit switch Ill closes its upper contacts to energize the magnet H0 and operate the valve m to the illustrated position. This 'vents the cylinder 18 and the pistons 19 immediately drop to lower the pinch rolls 88 onto the material.
  • the pinch rolls are driven by any convenient means, at the same peripheral speed as the rolls' I5, so as to cooperate therewith in moving the material back and forth.
  • the relay III After a slightly longer time, the relay III operates to bridge its contacts II 'Ib, maintaining the circuit for the magnet II3 by reason of the fact that the bridging contact slides along the contacts Illa.
  • the relay is adjusted so that the contacts IIIb are bridged after the material has emerged from the mill on the exit side, passed through the pinch rolls, and made one turn about the coiler.
  • the bridging of the contacts II'Ib causes the operation of magnet III to shift the valve I 08.
  • the cylinders 82 on the exit side of the mill thus operate to raise the associated pinch roll from the strip. The strip is thus free between the. winding and unwinding coilers, except where engaged by the mill.
  • valves I09 and I 08 also causes the operation of the cylinders 94 on opposite sides of the mill.
  • the roll 92 is thus raised into engagement with the material but is sufllciently spaced thereby from the roll 90 that the contact IOI remains in engagement with the contact I02.
  • the fluid pressure is continuously applied to the cylinders,
  • the controller I 05 When the pass is completed, the controller I 05 is restored to neutral position so that the trailing end of the strip stops between the mill and the pinch rolls on the" exit side thereof.
  • the relay II! is thus deenergized and substantially immediately opens its contacts to deenergize magnets H2 and H3.
  • the cylinders 82 are thus exhausted to the atmosphere and the pinch rolls dropped.
  • the cylinders 94 are exhaustedthrough check valves II8, the weight of the roll 92 and chucks 98 serving to force the accumulated 'fluld out of the cylinders.
  • the operating fluid for the cylinders 94 passes initially through expansion valves I I8 which slightly delays the lifting of the chucks 93 on starting a pass.
  • the next pass is accomplished in exactly the same manner. Reversal of the controller I05 energizes the relay I20 and this. in turn, causes sequential lifting of the pinch rolls 88 on the entering and exit sides of the mill. This cycle is repeated until the strip has been reduced to the desired gauge, when it is wound on a coller beyond the furnace on the exit side of the mill. The top work roll is then lifted by reversal of the screwdowns.
  • the switch II4 closes its lower contacts and operates the valve I01 to admit fluid under pressure again to the cylinders 18, whereby the pinch rolls 88 on both sides of the mill are lifted out of the way for the next flat rolling operation.
  • Figure 9 shows how the side guide actuators of Figure 1A are controlled.
  • the controller I5 When the controller I5 is shifted so as to cause the material to be fedfrom left to right, it closes contacts Hi. It

  • a single con 30 troiler m5 is employed and that it controls contacts Hit and H24, for example, simultaneously, in addition to the other contacts necessary to bring the motor Hi3 up to operating speed.
  • the system of Figure 9 is shown separately from that 35 of Figure 8 simply because it is a diagrammatic plan, whereas the latter is a diagrammatic elevation, but it will be understood that the two systerns are combined and under the common control of the controller 9B5.
  • the positions of the guideson opposite sides of the mill are re- 55 versed automatically with the reversal of the roll tables and the mill so that once the guides have been adjusted, they require no further attention until a different width ofmaterial has to be rolled.
  • the flattening rolls insure that the leading end of the strip will always be sufficiently flat to enter and engage the coiler properly to wind the strip thereon. This avoids the delays experienced heretofore incident to'the backing up of the strip 65 and repeating the entry thereof intothe coiler after a first unsuccessful attempt.

  • the automatic stop mechanism prevents loss, damage or injury in case the strip breaks during a pass. 10
  • the positive actuation of the side guides under the control of the main controller causes the strip to be properly started toward the mill and correctly sitioned with respect thereto before it actual enters between the mill rolls, aiter which no efiort is suflicient to correct an improper starting of the strip, because of'the great force exerted on the strip by the rolls.
  • the top guide 29 has an important function in preventing the coiling up of the leading end 01' the piece when rolling in the flat.
