Definitions

  • a rotary continuous casting machine has a rotor and side rings and an endless cover band defining a mold groove; the cover band makes contacts with the rings and displaces them yieldingly so that the cover band will be in pressure contact with the surface of a casting while the casting is in the mold.
  • the invention relates to the art of continuous casting, and relates more particularly to continuous casting machines of the rotary type.
  • the casting mold is formed by a portion of an angular groove that is open towards the exterior, and is formed on a rotating cooled casting wheel or casting drum, and a cover band covers that portion and moves synchronously therewith.
  • Casting machines of this type are used for the continuous casting of billets, particularly composed of aluminum, aluminum alloys, zinc and copper.
  • rotary continuous casting machines developed by Ilario Properzi and built by the firm Continuus which are usually connected to a multiple rolling mill, there are primarily cast metal rods, for instance of triangular or pentagonal cross section.
  • these metal rods are rolled to become wires of circular cross section, for instance of a thickness of 10 mm.
  • the resulting casting will be a band or slab that has a width that is far in excess of its thickness.
  • the instant invention primarily relates to the continuous casting of such metal slabs on [a rotary continuous casting machine.
  • Rotary casting machines now in use generally work satisfactorily. They are, however, deficient therein that in the casting mold during the solidification of the metal melt, there appears a shrink gap which widens gradually, so that the casting will for its major part be out of contact with the cover band and may even be out of contact with the casting wheel or casting drum itself. Shrink gaps of this type, however, adversely affect the removal of heat from the casting. Normally, the casting wheel drum is cooled, and the cover band is cooled, and by these instrumentalities heat is removed from the casting, promoting its rapid solidification. Air gaps which are formed by the aforesaid shrinking, on the other hand, constitute insulating layers between the casting and its surroundings, which affect adversely any rapid heat removal.
  • cover band is energetically cooled, such a resistance layer will not be very disturbing, as long as the casting product is a narrow endless slab of pure aluminum or pure zinc; present day rotary continuous casting machines, cast in large quantities slabs of pure aluminum of a width of from 100 to 200 mm.
  • the shrink gap will, of
  • Patented Dec. 17, 1968 course, be larger at the narrow sides than at the wide sides; these narrow side gaps, however, usually do not result in any adverse effects.
  • the shrink gap on the wide sides is found to be disturbing particularly during the casting of alloys which tend to sweat during solidification. This, for instance, is the case with aluminum magnesium alloys of one (1%) percent magnesium or more, as well as with aluminum zinc magnesium alloys and aluminum magnesium silicon alloys.
  • the sweating is particularly disturbing, as the surfaces of the billets or slabs usually are neither milled nor planed prior to the subsequent rolling.
  • the endless casting band, or slab, that emerges from the rotary casting machine is first passed through a control and regulating equipment and then is passed into the rolling mill that is synchronized with the rotary casting machine.
  • Roll-casting relates to the continuous casting of endless plates between two rotating rolls (see for instance The Continuous Casting of Steel, Scientific American, New York, Dec. 1963, pp. 75, 76).
  • the casting takes place between two circulating bands or belts, for instance as practiced in accordance with the Hazelett method (see the aforementioned application of Altenpohl et 211.).
  • it has been possible to cast continuously aluminum plates having a thickness of from 7 to 50 mm., and a width of from 800 to 1500 mm.
  • Similar efforts in connection with rotary continuous casting machines have been unsuccessful to date.
  • the cover band which is usually a steel band, in constructions heretofore used rests with its edges on two side rings that are rigidly connected to the casting drum and form thereon the side walls of the casting groove.
  • the cover band is suspended and guided by deflecting and tension pulleys.
  • the casting wheel or casting drum usually comprises a rim which defines an external surface that forms a part of a groove for the casting mold, and side walls.
  • cooling equipment for the rim.
  • the cooling is customarily carried out by means of flowing or sprayed water.
  • the cover band is often also subjected to cooling, namely near the mold cavity, usually by spraying its external surface with water.
  • the rim of the casting drum usually is made of a single piece; the side rings, which form the side walls of the mold cavity, are rigidly connected to the main portion of the rim.
  • the cover band will along the stretch where it forms the wide side of the mold cavity, be pulled at its center section towards the bottom of the mold cavity so that, in a mold having for instance a width of from 400 to 1200 mm., the mold cavity will be much smaller along the longitudinal middle line, than at the sides thereof. Under these circumstances it is not possible to cast plane slabs of the type necessary for rolling into sheet metal.
  • This contact between the cover band and the solidified casting also restrains the inward bending of the cover band into the liquid and into the partially solidified parts of the casting.
  • the rings are displaceable in the region of the mold cavity in a direction towards the axis of rotation of the drum, so that the height of these side walls of the mold cavity will gradually become smaller in correspondence to the shrinking of the casting.
  • the resilient yielding of the side rings within the region of the mold cavity avoids the occurrence of any shrink gap parallel of the cover band, not only for slabs, but even for rods.
  • This arrangement has the advantage that the cover band will, within the region of the mold cavity, by the pressure it exerts onto the casting, generate a reaction pressure by the rim.
  • This co-action of pressure and counterpressure has the effect that, in accordance with the instant rotary continuous casting machines for wide slabs, for instance of 400 mm. width or more, the cover band throughout the major portion of the mold cavity no longer can bend or vault towards the rim; the cross section of the mold cavity accordingly will substantially be uniform throughout its width.

  • the completely solidified metal is indicated at 19.
  • shrink gaps begin to form at 20 and 21, and become wider at 22 and 23.
  • the solidified slab 19 again makes contact with the surface of the rim 11, thus discontinuing the lower shrink gap 23.
  • the upper shrink gap 22 however, not only continues, but increases in thickness for an amount that corresponds to that of the lower shrink gap 23, and is due to the latters elimination.
  • the shrink gaps 22 and 23 form insulation layers filled with air, which are detrimental to a rapid and uniform cooling of the slab 19.
  • a shorter mold cavity furthermore, for instance extending only through about one-fourth of the circumference of the rotor instead of the usual one-half of the circumference, permits a reduction in the number of deflecting and tensioning pulleys from the usual four to three.
  • FIG. 3 there is shown a rotary continuous casting machine with four deflecting and tension pulleys 10, 25, 26 and 27.
  • a shorter mold cavity in accordance with the invention, makes it possible to substitute for the two pulleys 25 and 26 a single pulley 28, shown in broken lines in FIG. 3, providing at the same time for a correspondingly shortened cover band 12.
  • FIG. 4 there is shown a rotary casting machine having, in accordance with the invention, a shortened mold cavity 16 that extends only throughout about onefourth of the circumference of the rotor 11a.
  • Three deflecting and tensioning pulleys 10, 28 and 29 are provided which suspend and guide and move the cover band 12 in the usual manner, so that along the mold cavity 16 the cover band 12 will move synchronously with the circumferential speed of the rotor 11a.
  • the roll 30 serves a different purpose and does not participate in the suspensioning of the cover band 12.
  • Water spray nozzles 31 are provided for cooling the cover band 12 near the mold cavity 16, and wipers 32 are provided for guiding away the excess cooling water. Instead of cooling by water, however, cooling may be carried out by blowing air or water vapor onto the cover band 16.

  • the eccentricity of the rings 33 relative to the rotor 34 and its rim 42 has been exaggerated in FIG. 5.
