Definitions

  • the invention is described as embodied in the structure and operation of a continuous strip-casting machine in which the molten metal is injected under a controlled head or pressure into a casting region between the spaced portions of a pair of moving flexible casting belts and a continuous strip of solidified metal is delivered from the machine.
  • One of the moving belts is positioned generally above the other, and the spaced portions of the upper and lower belts confine the molten metal in a casting region between them and carry the molten metal along as it solidifies between them.
  • both the upper and lower belts are cooled by means of rapidly moving substantially continuous films of liquid coolant travelling along against their reverse surfaces adjacent to the casting region.
  • the two casting belts are individually mounted upon a pair of special carriages, and each belt is guided around its carriage in an elongated triangular path providing advantages in tensioning and steering of the belts.
  • Another advantage of this illustrative machine is its adaptability for providing a wide variety of different continuous casting conditions as may be desired by an operator for accommodating different kinds of metals or different alloy compositions.
  • the operator is enabled quickly and conveniently to adjust the machine for different types of casting operation.
  • the machine can be adjusted for injecting the molten metal through an injection nozzle or for casting with an open bath of molten metal or for a half-open bath.
  • the upper carriage is adjustable in position longitudinally with. respect to the lower carriage for adapting to these different types of casting.
  • a further advantage of this illustrative machine is provided by the swing mounting for the upper carriage which enables the upper carriage to be elevated and tipped laterally so that the casting region is opened up widely for convenient access and inspection.
  • This mounting also enables the upper carriage to position itself into self- United States Patent lice 3,167,830 Patented Feb. 2 196? aligning relationship with the lower carriage when the upper carriage is lowered so as to close the casting region in readiness for the casting operation.
  • FIGURE 1 is a perspective view of a continuous stripcasting machine embodying the present invention as seen looking at the input end of the machine into which the molten metal is introduced.
  • the tundish or container for the molten metal and the injector nozzle which is adapted for feeding molten metal into the machine are omitted from this view;
  • FIGURE 5 is a top plan view showing the upper belt removed and with parts shown partially broken away and in section for clarity of illustration;
  • FIGURE 10 is a cross sectional view of the coolant nozzle taken along the line 10l0 of FIGURE 9;
  • grooves are for the purpose of providing intense'icooling of the casting beltsi'adjacent to the injection nozzle, as will be explained further below.
  • these units In their function of maintaining the coolant layer 43, these units have scoop surfaces for scooping off the excess coolant and for directing this removed coolant into a series of gutters, such as the gutter 63 indicated in FIGURE 3. It will be understood that other similar coolant gutters are used in conjunction with the other coolant units 66, but for purposes of clarifying the illustration, these other gutters are not drawn.
  • There is a first coolant application unit 62 for each belt which differs from the other units 60 in that the units 62 do not have scoop surfaces.
  • the molten metal 10 is injected along a straight path while the adjacent flights 75 and 76 of the upper and lower casting belts 14 and 16 converge toward the injected metal from opposite directions and then curve into tangential relationship with the path of the injected metal so as to define the casting region.
  • the curving portions of the two casting belts are intensely cooled as they converge toward the path of the injected metal.
  • the injected metal is fed into the casting region C through the passages 26 of the injection nozzle assembly 12.
  • the insulating nozzle 25 is adapted to be slid out or inward through the shell 22, and it can readily be removed and replaced when worn or broken. 26 have a diameter equal to approximately one-half of the thickness of the nozzle 25.
  • the first set 46 of the back-up'roller's is constructed ditIcrently from the remaining back-up rollers 44.
  • the peripheral ridges d7 of this first set of back-up rollers 46 are reduced in height so thatthe roller shaft itself can perpendicular to the plane of the casting region. This skewing causes the belt to approach the respective tension. rollers as and 313 at a slight deviation from the longitudinal axis of the machine. As a result, the belt is caused to shift gradually laterally one way or the other in the desired drection.
  • This type of steering action is described in detail and claimed in our said prior :copending application Serial No. 722,605.
  • FIGURES 9 and ll the nozzles 850! 85a at the ends of'the oval coolantfeed tubes 84 direct jetsil of the coolant against the curving reverse surface of the belt at a slight'angle to a tangent at the region 87 wherein the jets first come into contact with the belt]
  • a tangent 88 to the belt at the region 87 and the angle on between the direction of the jet and thistangent is less than 10.
  • This cantilever beam 108 has a generally U-shaped cross-section as seen in FIGURE 3 as defined by a forward plate 109, a rear plate 110 and a bottom web 111.
  • the inboard ends (right ends in FIGURES 2 and 4) of the beam plates 109 and 110 extend upwardly in a sweeping curve and are rigidly connected to the front end of a chas sis torque stiffener tube 112.
  • the inboard end of the front beam plate 109 continues up so as to support a longitudinally adjustable swing pivot mechanism 114, which carries the upper carriage and will be described in detail further below.
  • the inboard end of the rear beam plate 110 sweeps down from the top of the torque stiffener 112 and rigidly supports the coolant supply manifold 55.
  • This tubular bracket is rigidly spanned between the cantilevered swing arms 150 and 152, and a saddle cap 168 passes over the tubular bracket 166 and is connected at its opposite sides to the saddle 164.
  • a lower extension 160a which extends down through a slide bearing 170 in the bottom end of the hydraulic cylinder 154.
  • a wide arching web plate 172 extends above the tubular bracket 166 and is rigidly secured between the two swing arms. Also, a vertical stiffening web plate 174 extends between these arms near the adjustable swing pivot mechanism 114.
  • this upward swinging movement provides a large headroom clearance space for access into the region between the two carriages.
  • the outboard side of the upper carriage U raises even higher than the inboard side so as to provide the most effective working space between the carriages, for example, for making adjustments or replacements in the machine.
  • moving edge dams 68; and 70 are replaced with higher or lower dams for casting thicker or thinner material.
  • the full Weight of the" upper carriage is not allowed to rest upon these moving dams,
  • spacer blocks 178 (FIGS. 1 and 4-) positioned along on opposite sides of the casting region between the edges of the respective pairs of carriage frame members 126and 132, and 127 and 133.
  • the articulated mounting of the upper carriage enables it to aligne itself with thelower carriage as it rests upon these spacer blocks 178.
  • the insulatingnozzle portion 25 is inserted directly between theparallel portions of the two belts as described pretwo adjacent moving edge dams prevents the molten metalfrom leaking out of the input end of the casing region.
  • the projecting end of the nozzle 25 engages 'snuglybetween the moving edge dams 68' and 70, and
  • the molten metal is prevented even though the-"spaces betweenthe moving'dams andthe stationary nozzle are not watertight.
  • the insulating nozzle 25a rests down against'the crown of the lower beltwhere it passes over the lower nip roll30 and is held in position by atransverse stiffening member 216, such as an I-beam,
  • atransverse stiffening member 216 such as an I-beam
  • the 'nozzle 25 forms a barricade to close the back end of the half-open bath 208.
  • the moving edge dams engage opposite. edges of the nozzle'25a so as'to prevent-leakage similar to the engagement between the moving edge dams and thenozzle 25' in FIGURE 6; j
  • stationary edge dams are provided for restraining the molten metal at opposite sides of the open bath projecting above the moving edge dams 68 and7tl; for example, these stationary edge dams are as disclosed and claimed in US. Patent No. 2,904,860.
  • FIGURE-14D the machine is shown as being arranged for pouring with a fully open bath or pool of molten metal 212.
  • the metal is prevented fromtlowing out of the rear of the pool 212 because its level is below the crown of 'the lower belt 14 where it passes over the'lower nip 1011.30.
  • the upper carriage is shifted progressively farther toward the output end as the strip thickness is increased when using a fully open bath procedure, as shown in FIGURES 14D and 14E.
  • This longitudinal adjustment progressively opens up the pool212 and 214, assuring that the liquid surface first engages the upper belt at a point P before the upper belt has moved into the casting region. This prevents the entrapmentof gas between the exposed liquid surface and the upper belt after it has entered the casting region.
  • the belt-tensioning roller 36 is a hollow cylinder mounted at its opposite ends on suitable bearings 228, such as roller bearings on a fixed internal shaft 230 which extends between the tensioning arm 226 and a corresponding tensioning arm 227 at the inboard side of the carriage.
  • suitable bearings 228, such as roller bearings on a fixed internal shaft 230 which extends between the tensioning arm 226 and a corresponding tensioning arm 227 at the inboard side of the carriage.
  • the planes of the two planar portions of the belt adjacent to the tensioning roll 36 define an acute angle B at the tensioning roll.
  • the tensioning arms 226 and 227 are swung into their belt-tensioning positions, their eifective lever arms approach closely to parallelism with the bisector 234 of the angle B.
  • the effective lever arm of the tensioning arm 226 or 227 is defined as a line 236 passing through the axes of the shafts 224 and 230.
  • a toggle effect is provided which markedly reduces the magnitude of the force required to produce the desired tension below that for previous arrangements, and thus enables much wider carriages and casting belts to be used for casting wider slabs.
  • a further desirable eifect is obtained in that the magnitude of the tension does not change very much for small angular movements of the lever arm 236 with respect to the bisector 234-. Therefore, if either of the tensioning arms should become deflected slightly from its desired position, this will not cause any appreciable difference in the actual tension applied to opposite edge portions of the belt.
  • the crescent-shaped guide members 246 and 248 are I positioned so thatthe moving edge dams 68 and iii become fully straightened out as they pass over the uppermost guide wheel 25%, and the moving edge-dams are directly aligned by this last wheel with the plane of the casting region before the moving edge damscome into contact with either of the casting belts. In this way the adjacent ends of the, individual blocks '71 of each of these moving edge dams become parallel and close together be-- fore the moving edge darn moves in between the belts.
