Definitions

  • molten metal e.g., steel
  • An arcuate channel is generally used in continuous casting machines in order to reduce the overall height of the machine.
  • the flowthrough mold is usually water-cooled and is often reciprocated to ensure a smooth flow.
  • the metal exits the mold and enters the channel it is only partly solidified and has a liquid center of substantial depth contained within a solid outer skin. As the slab moves within the arcuate channel, it is sprayed with water in order to advance the solidification process.
  • a steel plug is placed some where in the vicinity of the top of the arcuate channel.
  • the plug serves as a temporary bottom for the slab.
  • the drive of the plug is terminated.
  • the drive mechanism is simply disconnected from the plug and the plug remains attached to the forward end of the slab and continues to move with it along the horizontal conveyor. The plug is subsequently separated from the forward end of the slab so that it can be re-used.
  • theplug is physically separated from the forward end of the slab near the end of the arcuate channel rather than simply ceasing to drive it and then letting it continue to move with the slab.
  • pinch rollers at the leading end of the horizontal conveyor straighten the slab and continue to pull it forward so that a slab of any desired length can be formed.
  • a common prior art technique for positioning the plug is to utilize a heavy chain attached to the plug which can be moved through the arcuate channel.
  • a heavy chain attached to the plug which can be moved through the arcuate channel.
  • U.S. Pat. No. 3,426,835 issued to A.'Michelson on Feb. I 1, I969 and entitled Starting Mechanism For Continuous Casting Machine, there is disclosed a carrier chain which is contained within the channel prior to the start of'a casting. One end of the chain is attached to the starting plug at the top of the channel. As molten metal is poured from a tundish through the mold cavity, the chain is pulled so that the plug descends the arcuate channel. The chain, as it is being pulled down the channel, is directed out of the casting path,at the front end of the horizontal conveyor.
  • the plug conentitled Continuous Casting Apparatus Having Mold Plug for example, there is disclosed a mechanism for moving the mold away from the top of the arcuate channel, placing a plug underneath it, and then replacing the mold with the underlying plug at the top of the channel. In this way, it is not necessary to move a new plug all the way up through the channel prior to a new casting.
  • two internal endless chains pull the plug downward at a controlled speed.
  • a piston rod is operated to force the plug out of the channel.
  • the closed loop chains since they need not be returned to initial positions, together with the mechanism for inserting a plug at the top of the channel, reduce the setup time of the Foldessy machine.
  • the machine suffers from several disadvantages.
  • One of these is the fact that the internal closed-loop chain arrangement makes it difficult to utilize an arcuate channel, and consequently the Foldessy technique appears attractive only for purely vertical machines which thus must be quite high.
  • the Foldessy patent discloses only a purely vertical machine.
  • the Foldessy machine requires a different mold for each plug size, each plug requires an internal lug-engaging mechanism, and the mold must be moved away (thereby requiring the breaking of the water-hose connections) each time a new plug is put in place.
  • the chains are intermeshed with the rollers under the mold, it takes considerable time to repair the machine following an accidental metal breakout.
  • a starting plug is inserted on top of an arcuate channel while the mold is pivoted slightly out of the way (not enough to require the breaking of watephose connections).
  • Two open-ended racks are positioned along the sides of the channel each having a head which can grip an outrigger, or arm, which extends from a respective side of the plug. The two racks are initially in the up position with their respective heads being at the level of the mold. When the mold is moved out of place and a new plug is lowered on top of the channel, the two rack heads grip the outriggers on the plug.
  • the mold is then returned to its normal position and a new casting is begun by driving the racks, each of which is provided with a series of teeth on its upper surface, by respective pinions while molten metal is poured through the mold.
  • the racks attached to the plug reach the bottom of the arcuate channel, .the heads are released from the plug Outriggers.
  • the plug then continues to move with the slab as the slab is pulled forward by the pinch rollers which also straighten it.
  • the two racks, which are outside the channel are returned to their starting positions so that the heads are in place to receive a new plug as soon as pouring of the molten metal through the mold ceases so that the mold can be moved out of the way.
  • FIG. 1 depicts a continuous casting machine constructed in accordance with the principles of the invention
  • FIG. 2 depicts in greater detail the mechanisms at the top of the arcuate channel and the manner in which a starting plug is placed at the top of the arcuate channel;
  • FIG. 3 is similar to FIG. 2 and shows the starting plug in place at the top of the channel;
  • FIG. 4 depicts in detail the head at the end of each side rack for gripping one arm of the starting plug and further shows the manner in which the gripping element within the head is moved as a starting plug is lowered into the arcuate channel;
  • FIG. 5 depicts the head of FIG. 4 after the plug has been lowered and gripped by the head
  • FIG. 6 depicts the manner in which each of the two heads is automatically released from the plug after having moved through the arcuate channel
  • FIG. 7 is a sectional view taken through the line 7--7 of FIG. 1;
  • FIG. 8 is a sectional view taken through the line 8-8 of FIG. 7;

  • FIG. '1 depicts in side elevation the major components of a continuous casting machine 10, of the type shown in the above-identified patents, but constructed in accordance with the principles of my invention.
  • the machine includes a frame 15 which supports both a ladle 16 containing molten metal and a conventional tundish 17.
  • the molten metal is transferred from the l'adle to the tundish in a manner known in the art so as to control the pouring of molten metal from the tundish into flow-through mold 18 at a constant pressure.
  • the mold is held on top of platform 19 which is pivotally connected to two arms 20 and 21 on each side of the platform. These two arms, on each side, are in turn coupled to control mechanism 23.
  • the control mechanism moves the four arms so that platform 19 and mold 18 move in two distinct ways.
  • the second way in which the platform and mold move is a short reciprocating up-and-down motion during the actual casting process to ensure a smooth flow of metal through the mold as is known in the art.
  • the arcuate channel is designated by the numeral 33, there being a plurality of rollers such as rollers 34 which define the channel height.
  • rollers 34 which define the channel height.
  • the rollers 34 and the racks are contained within arcuate-shaped frame member 30.
  • a channel entrance frame 22 shown most clearly in FIG. 2, which includes a plurality of entrance rollers 54 and water spray jets 53.
  • a similar entrance frame 55 is disposed on the other side of the channel as shown in FIG. 2.
  • water spray jets are also provided between rollers 34 within frame member 30 in a conventional manner to further cool the cast metal as it moves down the arcuate channel.
  • FIG. 1 also depicts one of the rack heads 24 in its starting position near the top of the channel with a starting plug 25 also shown as having one of its outwardly extending arms gripped by the rack head.
  • the details of the rack head will be described below with reference to the other drawings.
  • a frame section 40 which contains a plurality of rollers 41 which define a horizontal channel 42. These rollers not only straighten the metal slab as it exits the arcuate channel but also continue to transport it in the horizontal direction.
  • the two racks 31 also pass through frame section 40.
  • Each of the racks is driven by a respective pinion 43.
  • the respective rack is moved to the right in FIG. I and follows the path shown by arrows 47 within storage frame 46.
  • the storage frame serves to provide an area for containing the racks as they are withdrawn from frame section 30.
  • each rack head 24 is that shown in FIG. 1, each pinion moving in the clockwise direction until the respective head is near the top of the arcuate channel as shown.
  • the racks move in the downward direction, they move until the heads are at a position within frame section 40 at which they release the starting plug, as will be described below. (As will be apparent to those skilled in the art, the storage frame can be located at a lower level if desired.)
  • FIG. 2 depicts the manner in which a starting plug 25, having two outwardly extending arms 25a, a slabsupporting section 251; and reinforcing ribs 240, as seen most clearly in FIG. 9, is lowered into the arcuate channel, the entrance to which is defined by rollers 54 contained within frame elements 22 and 55.
  • Platform 19 contains a central section which supports mold l8 and two downwardly extending arms on either side of frame section 55. Each of the downwardly extending arms is pivoted to two respective links and 21, as shown by pivot elements 84.
  • Each of arms 20 is pivoted to a movable bracket 82 as shown by the numeral 83, and each of the arms 21 is pivoted to a stationary bracket 72 at tached to control mechanism 23.
  • actuator 85 Within the control mechanism are two piston actuators 80 and 85, having respective piston rods 81 and 86.
  • actuator 85 is controlled to pull in rod 86
  • actuator 80 is controlled to push out rod 81.
  • the pulling in of rod 86 causes link 21 to rotate upward in the direction of arrow 88.
  • the pushing out of rod 81 causes bracket 82 to move to the right as shown by arrow 73.
  • Frame member 55 which carries rollers 54 and water spray jets 53, is pivoted at 57 and is caused to move slightly clockwise in the direction of arrow 56 (by a mechanism not shown) prior to the lowering of the plug 1 into the channel. This facilitates insertion of the plug.
  • FIG. 3 shows the manner in which mold 18 is returned to its normal position after plug 25 is lowered and cables 52 are removed.
  • Actuator first causes inward movement of piston rod 81 so that bracket 82 moves in the direction of arrow 93. This causes platform 19 and mold 18 to move in the direc tion of arrow 91 to a position directly above the upper end of plug 25.
  • actuator 85 causes rod 86 to move downward in the direction of arrow 94 so that platform 19 and mold 18 are lowered.
  • the mold is conventional and includes an inner lining 18 a, a water jacket 18b (with means, not shown, for moving water within the jacket to cool the metal poured through the mold) and an outer supporting structure 180.
  • the clockwise and counter-clockwise motion of link 21 around pivot 87 causes platform 19 and mold 18 to alternately move up and down as molten metal is poured from tundish 17 through the mold as shown by arrow 90.
  • each rack 31 On each side of the channel there is a rack 31 at the upper end of which there is provided a head housing 24.
  • the housing is a continuation of the rack and includes teeth 32 which are of the same shape as the teeth on the links comprising each rack.
  • a pair of rollers 70 are provided on the two sides of each of the head housings. These rollers, as well as comparable rollers which interconnect the different links of each rack, move through channels, to be described below, to guide each rack and its housing so that they are moved along a path parallel with that of the arcuate channel.
  • each head housing there is a gripping element 60 seen most clearly in FIGS. 4 and 5.
  • the gripping element has a forward slot defined by edges 60a and 6012, the dimension of the slot conforming to one of the arms 25a of the starting plug.
  • the gripping element also includes a central section 60d and a lower section 60e which contains two pivots 101. Each of these pivots serves to connect the gripping element to a respective one of internal links 102 and 103. The two links are in turn connected to pivot elements to the head housing 24.
  • Link element 103 is also pivoted, as shown by numeral 104, to a rod 105 which extends through the head housing.
  • the rod is provided with two stops 107 and 108, and a spring 106. The spring tends to force the rod downward (out of the housing). This, in turn,
  • link 103 causes link 103 to rotate in the counter-clockwise direction around pivot 100 and thus results in gripping element 60 being forced to the left out of housing 24.
  • FIG. 5 shows the plug in the starting position, after platform 19 and mold 18 have been returned to their normal positions.
  • FIG. 4 further shows the teeth 32 contained on each head housing and each rack link, as well as a pin 116 for connecting the uppermost link in each rack to the respective head housing.
