Definitions

  • the head After passing through a straightener roller mechanism, the head is detached and follows a horizontal path with the strand, but the starting bar is diverted in a vertically upward path for storage clear of the adverse conditions which prevail at the lower level.
  • Power actuated means are provided for initiating advancing and retracting the starting bar to and from the straightener mechanism.
  • Means are provided for positively latching the bar in its home position of storage.
  • the strand enters vertically through the upper end of a curved roller apron which changes the direction of the strand to horizontal and directs it to a straightener mechanism.
  • the starting bar is advanced reversely through the roller apron until its head end registers in the bottom outlet of the mold.
  • the starting bar is then withdrawn from the roller apron and the partially solidified strand follows.
  • the bar is separated from the strand and directed to a storage position while the strand continues in another path.
  • the method of handling and storing the articulated type of starting bar has been to withdraw it through the straightener mechanism and divert it downwardly below the horizontal pass line of the strand as it exits from the straightener rolls.
  • This means that the starting bar is stored below the conveyor on which the continuous strand is cut into suitable lengths in which case the starting bar often becomes badly fouled with various kinds of refuse including slag that is produced by the cutting torches which are used to cut the strand.
  • An object of the present invention is to overcome the above-mentioned problems by providing an articulated starting bar which may be stored in a convenient manner above the pass line of the strand and clear of the region where the starting bar would be subject to fouling or would interfere with arrangement of other components of the machine.
  • Another object of this invention is to provide novel actuator and latching means for initiating the advancement of the starting bar toward the mold and for finally retracting the same to its home or storage position.
  • An adjunct to this object is the provision of means for positively engaging the mold remote end of the starting bar with the actuator and for positively securing the bar in its stored position.
  • the new starting system for a continuous strand casting machine comprises a starting bar storage structure which extends principally in a vertical direction above the pass line of the strand.
  • the inlet end of the storage structure has a guide section which diverts all but the head end of the starting bar from its horizontal path through the straightener mechanism to its vertical path in the storage structure.
  • the guide section is so designed that the head end of the starting bar is caused to remain with the leading end of the strand in which case the head end may be retrieved and reconditioned for the reuse on the next occasion of starting.
  • FIG. 1 is a side elevational view of a continuous casting machine embodying the invention
  • FIG. 2 is a side elevational view showing more details of the starting bar storage and actuating system, the strand straightener and'the withdrawal mechanism, the latter being shown in phantom lines;
  • FIG. 3 is a side elevation sectional view of a part of the guide section which diverts the starting bar in one direction and allows the head member and strand to follow a pass line in another direction;
  • FIG. 4 is a view of the strand exiting side of the guide section
  • FIG. 5 shows the head end of the starting bar partially in section
  • FIG. 6 is a sectional view taken on a line corresponding with 6-6 of FIG. 5;
  • FIG. 7 is a side elevational view of the starting bar advancement initiating and retracting actuator with parts removed, and of the remote end of the starting bar and its latching mechanism;
  • FIG. 8 shows a section of one of the hinge joints of the articulated starting bar taken on the line 8-8 in FIG. 2;
  • FIG. 9 is a cross section of a joint in the starting bar head taken on a line corresponding with 99 in FIG. 5;
  • FIG. 10 is a vertical cross section of the starting bar and latch arm taken on the line corresponding with l0l0 in FIG. 7.
  • FIG. 1 illustrates some components of a continuous billet or strand casting machine. Most of the structural steel members which support the illustrated components have been omitted from the drawing for the sake of brevity.
  • the casting machine comprises a ladle car 10 which is supported on tracks 11 so that it may traverse over several casting machines operated in parallel.
  • a ladle 12 which has a bottom gate valve, not shown, is used to transfer molten metal to the casting machine by way of a tundish 15.
  • the ladle is shown supported on car 10.
  • a tundish 15 is located below the ladle for receiving molten metal out of the bottom of ladle '12 under control of the operator.
  • the tundish l5 admits molten metal into a flow-through mold l7.
  • Mold 17 is sur- 3 rounded by a water cooling chamber which effects solidification of the outer skinof the strand that is formed in the mold so that it will maintain its shape as it emerges from the mold.
  • the mold 17 is supported on an oscillating vmechanism which is marked 18.
  • the roller apron may be made in sections and be fastened at a number of places, one of which is exemplified by the anchor 21.
  • the roller apron comprises a pair of tracks 22 and 23 which are spaced apartto provide a guide for the starting bar rollers as will be described later.
  • Also in the roller apron are a series of staggered stationary rollers 24 which induce a curve in the strand 31 as it traverses down the apron to a known type of straightener and withdrawal mechanism which is generally designated by the number 25.
  • the straightener and withdrawal mechanism 25 will now be described to the extent necessary to establish its relationship withthe present invention.
  • the mechanism 25 will be seen to comprise upper and lower pairs of withdrawal rollers 26, 27 and 28,29.
  • the fragment 31 of the strand shown in FIG. 2 is assumed, of course, to have passed down roller apron from mold 17 and is shown as having passed through the entry rollers 26 and 27 of the straightener mechanism.
  • Exit rollers 28 and 29 and entry rollers 26 and 27 are adapted for being driven with hydraulic motors which are symbolized in FIG. 1 and assigned the reference numerals 32, 33, 34 and 35.
  • the hydraulic-supply system for these motors is such that they may be driven as independent pairs 28, 29 and 26, 27 or they may be driven simultaneously.
  • the motors and rollers may also be advanced and retracted vertically so as to selectively engage or disengage with strand 31 or with the starting bar which is generally designated by the reference numeral 36 in FIG. 2.
  • the hydraulic system for operating motors 32 35 is not shown.
  • starting bar 36 is shown still attached to strand 31 which has been admitted through exit rollers 26 and 27. This condition prevails only when the casting process is being initiated.
  • starting bar 36 is diverted into its storage structure 37 by means of a guide section 38 which also permits the strand 31 to continue along its horizontal pass line so that the strand will run onto a cut-off table 39 as can be seen in FIG. 1.
  • the cut-ofi table 39 is equipped with a burning torch mechanism 40 which is adapted for following along with strand 31 so that it may cut the strand straight across to desired lengths.
  • the starting bar was stored under cutofitable 39 in which case the bar was often adversely afiected by the slag which is incidental to use of a buming torch and there were occasions when the starting bar itself was damaged by the flame of the torch.
  • the articulatedstarting bar 36 comprises a series of links 41 which are pivotally connected byshafts 42.
  • the opposite ends of the shafts have rollers 43 which run on the inside of spaced apart tracks 44 and 45, for instance.
  • the tracks for guiding the starting bar in storage structure 37 are similar in construction and arrangement to tracks 22 and 23 in roller apron 20.
  • the cross sectional view of the tracks may be seen in FIG. 10. They comprise channels or angle irons each of which. has a laterally extending leg 46, 47, 48 and 49.
  • a typical pair of tracks 46 and 47 are spaced apart from eachother to providea runway for the rollers 43 which are carried on the starting bar link shafts 42.
  • the starting bar 36 runs on these similar tracks in both the roller apron 20 and starting bar storage structure 37.
  • the head end 50 of starting bar 36 is separable from the principal portion of the starting bar in which case the principal portion may run up for storage into storage structure 37 and the head end 50 may continue with the strand, as is suggested by the head end being shown in broken lines, after it has been separated from the main portion of the starting bar.
  • the head has a guide cone, not shown, which is attached only when the starting bar is being advanced toward mold 17 and is removed just before it enters in which case the head of bolt 53 closes the bottom opening of mold 17 prior to initiating withdrawal of strand 31.
  • the guide cone is fastened temporarily to the starting bar head 52 by slipping it over a bolt 53 which has a pin 54 securing it to the head.
  • the head 52 is pivotally connected to a link 55 by means of a pin 56. The details of this connection may be seen in the cross section shown in FIG. 9.
  • the shaft 56 is suitably grooved at its opposite ends to receive a retainer 'snap ring 57 which is secured against a washer 58.
  • the first link 55 next to the head terminates in an open hooked portion 59 as can be seen in FIGS. 2, 3 and 5.
  • the second link 60 whichstays with the main part of the starting bar carries a transversely extending pin 61 and a stop pin 62.
  • head 50 cannot be rotated clockwise on pivot pin 61 because of interference by stop pin 62.
  • pin 61 may be withdrawn from hooked portion 59 in which case the main part of the starting bar may be diverted upwardly into its storage chamber 37 as shown in FIG. 2 and the separated head 50 may continue along the horizontal pass line.
  • FIG. 6 A sectional view of the separable hinged coupling is shown in FIG. 6.
  • the guide section 38 comprises a pair of tracks 66 and 67 on which the guide rollers 42 of the starting bar may run. Tracks 66 and 67 in the guide section align with tracks 44 and 45 in storage structure 37.
  • the guide section is provided with a gate 69 which is mounted on a gate pivot pin 70. Gate 69 can thereby be adjusted for effectuating proper disconnection of pin 61 in the starting bar from hook 59 in the head member 50.
  • guide section 38 has a pair of spaced apart side walls 71 and 72 which provide a space for the starting bar to run upwardly on tracks 66 and 67 and another space for strand 31 to continue in its horizontal path toward cut-off table 39.
  • the articulated starting bar will be stored in storage structure 37.
  • the starting bar 36 Before beginning to pour metal into mold 17, it is necessary to advance the starting bar 36 from its storage structure 37 through the straightener and withdrawal mechanism 25 and through roller apron until guide cone, not shown, which is temporarily at the head end of the starting bar approaches the bottom of the mold 17. The guide cone is then removed and the starting bar is advanced until the head of bolt 53 plugs the mold. Initially, the head end 50 of the starting bar is advanced from the storage structure to a position between exit rollers 28 and 29 of the straightener and withdrawal mechanism 25.
  • This initial movement is effected with a power actuator at the remote upper end of the starting bar.
  • the actuator will be described in detail later.
  • the actuator is adapted to advance the starting bar a short distance from its home position and then separate from it so that the bar may be advanced by driving exit rollers 28 and 29 of withdrawal and straightener mechanism 25.
  • the head 50 of the starting bar is engaged by the strand exit rollers 28 and 29 by lowering the upper exit roller 28 to effect a frictional drive with the starting bar.
  • Hydraulic motor 34 is then driven and the rollers advance the starting bar until the remote end of the starting bar is uncoupled from the actuator.
  • the hydraulic motors 34 and 35 are then operated to further advance the starting bar until its head 50 is between entry rollers 26 and 27 whereupon the latter are closed and hydraulic motors 32 and 33 are energized to continue advancing the starting bar up roller apron 20 until the head of bolt 53 at the head end of the starting bar registers in the bottom of mold l7 and closes its opening.
  • the starting bar When the initial charge of metal in mold 17 has cooled sufficiently to form a skin that will maintain its shape, the starting bar is withdrawn from apron 20 by applying reverse power to hydraulic motors 3235 to thereby drive entry rolls 26 and 27 and exit tolls 28 and 29 reversely in which case the starting bar will be withdrawn down roller apron 20. Under these circumstances, of course, the starting bar follows its tracks and goes back to storage position inside of storage structure 37. The starting bar is retracted under the driving influence of the straightener and withdrawal mechanism 25 until the remote end of the bar is recoupled with the power actuator located above.
  • pin 61 at the end of the starting bar separates from hooked element 59 on head member 50 and the strand 31 which is being withdrawn continues, with the head member attached, onto the cut-off table 39.
  • the starting bar is diverted upwardly from the horizontal path that is followed by the strand.
  • a hydraulic cylinder 75 at the top end of the starting bar storage structure 37
  • This cylinder is part of the actuator for initiating advancement of the starting bar and for retracting the same to its home position after it is separated from the strand.

  • Ram 76 has a clevis 77 at its end as can be seen best in FIG. 7. The ram 76 and clevis 77 extend between the tracks on which the starting bar rollers 43 run.
  • the clevis is pinned at 78 to a guide clamp 79 which has a depending tongue 80.
  • the guide clamp is provided with rollers which run on the tracks 44 and which in respect to FIGS. 2 and 7 will be called the upper tracks for present purposes.
  • Connected with guide clamp 79 are the last links 81 and 82 in the series of links which comprise the starting bar.
  • Link 81 is held coupled with guide clamp 79 by means of a latch arm 83 that is pivotally connected at 84 with tongue 80 which extends downwardly from the guide clamp 79.
  • Latch arm 83 has two upwardly extending spaced apart legs 85 and 86 as can be seen in FIGS. 7 and 10.
  • Legs 85 and 86 each have horizontal extensions or tips such as the one bearing the numeral 87, for engaging a shoulder 88 on link 81.
  • the latch arm 83 also carries a pair of rollers 90 and 91 which are joumaled on a transverse shaft 92 as can be seen in FIGS. 7 and
  • the latch arm 83 has two states in one of which the power actuator is engaged with the starting bar as shown in solid lines and the other of which the starting bar is disengaged from the actuator as shown in broken lines.
