Definitions

  • This invention relates generally to the continuous casting of metal and is more particularly concerned with the cooling of molten metal in the peripheral casting groove of the casting ring of a continuously rotating casting wheel.
  • mold cavity configurations which are defined by the groove shape and which determine the cross sectional characteristics of the cast metal, are available. Such shapes may range from a flat strip to a circular rod. Angular shapes are also conventional; thus, in the present presentation of the inventive concept, a bar of trapezoidal cross section is formed having a narrow base face, diverging side walls of greater width than the base, and a top surface formed by the mold closing band, the top surface being of greater width than the side faces or base.
  • the rate of heat dissipation along wider faces should be appropriately greater than the rate of heat dissipation from a narrower face in order to maintain a cross sectional uniformity of heat dissipation at the various surfaces of the bar.
  • the present invention is an improved cooling means for providing separated coolant channels within the casting ring adjacent the casting groove together with separately controllable coolant flow means for each, thus providing separately controllable rates of heat exchange along the separate walls of the casting groove.
  • the present invention comprises generally an annular casting ring presenting a peripheral mold cavity groove, in combination with a plurality of separate channels therein adjacent the casting groove side walls and floor, and independently controllable pressure means for supplying coolant to said channels and for controlling the velocity of the coolant fluid therethrough.
  • the plurality of channels allows a large volume of coolant to pass adjacent the casting groove while segregating the flow so that the cooling rate around the casting groove can be selectively controlled.
  • FIG. 1 is a front elevational view of the casting machine showing a first embodiment of the present invention
  • FIG. 2 is a front elevational view of a casting machine showing a second embodiment of the present invention
  • FIG. 3 is a cross-sectional view of the first embodiment of the present invention taken along the line 33 in FIG. 1;
  • FIG. 4 is a partial side view of the first embodiment of the present invention taken along the line 4-4 of FIG. 3 showing the inlet and outlet positions and the dam within the rear cooling channel;
  • FIG. 5 is a partial side view of the first embodiment'of the present invention taken along the line 55 in FIG. 3 showing the inlet and outlet posoitions and the dam within the front cooling channel;

  • a pipe 41 having flow control valve 42 therein extends from the source 40 to a central fluid passage 43 within the left hand supporting shaft 16. From the passage 43, the fluid is delivered to the channel 22 by Way of elbow 44, flexible connector 45, and fitting 46 to the channel 22. From the channel 22, coolant fluid exits by way of the fitting 47, flexible connector 48 (see FIG. 6) and elbow 49 leading to exhaust manifold 50 extending through the right hand support shaft 15. From the exhaust manifold 50, the discharge coolant fluid from allrthe channels is discharged through the conduit 51 shown in FIG. 1. As indicated in -FIG.' 1, the inlet fitting 46 for the channel 22 extends through the cover plate 25 of the groove 22 closely adja-.
  • a dam 54 is provided in the channel 22 to restrain the fluid from counter-flow in counterclockwise direction.
  • the dam 54 is formed with an intercommunicating port 55.
  • a separate intermediate passage 56 is provided in the left supporting shaft 16 to which coolant fluid is supplied from the pressure source 40 through the intermediate pipe 56 under control of the valve 57.

  • a perforate dam 60b is provided in the channel 33 in the manner of the dam 60 for controlling circulation and for preventing air bubbles.
  • each channel is supplied through an independently controlled flow valve.
  • Such independent control regulates the flow velocity in each channel.
  • the velocity of the cooling medium is an important factor to be considered along with volume and initial temperature .of such medium.
  • the flow valves 42, 57 and 72 may be separately adjusted to insure the desirable flow velocity appropriate to the specific requirement of each wall for its demand for heat dissipation.
  • the basic construction of the left side of the casting wheel is substantially similar to the construction of the wheel of FIG. 3.
  • the wheel of FIG. 7 includes the left hand disk 12 with the boss 14 together with the left hand supporting shaft 16.
  • the bearing sleeves 17 and the supporting stanchions 18 are also as shown in FIG. 3.
  • a vertically disposed retaining annulus 100' is provided, secured and spaced as in the right hand disk 11 of FIG. 3, by nuts and bolts 26 and 27.
  • the casting ring 101 also departs from the teaching of the construction of the casting ring 41 of FIG.
  • the ring 101 is of composite construction having a ring body 102 cast onto a casting groove forming liner 103 defining the casting groove 104.
  • the heat exchange tubing for the coolant fluid hereinafter discussed in detail, is in direct contact with the liner 103.
  • the important characteristic of the liner 103 is its heat conductivity which provides effective and eflicient heat exchange between the metal and the coolant tubes.
  • the cooling is. achieved by the tubes in contact with the liner 103, the heat conductivity characteristics of the material of the body 102 of the ring are not as critical as where the ring itself is the primary means of heat dissipation.
  • heat conductivity can be neglected in preference to material of greater strength.
  • the present construction lends itself to convenient formation by locating the coolant tubes in contact with the liner 103 along its external face, and casting the ring body material on the liner 103 so that the tubes are embedded in the body material, thus substantially welding the liner, tubes and body together.
  • the arrangement for the supplying and discharging of coolant fluid differs from the arrangement of FIG. 3 in that the left hand supporting shaft 16 defines a single internal coolant inlet flow passage 105 to be supplied by pipe 106 under control of flow control valve 107 (FIG. 2) from a fluid pressure source such as the source 40 of FIG. 1.
  • the left hand support shaft 16 is extended to the right with its coolant inlet flow passage 105 extended therewith to a first integral crossbeam 108 having a radial duct 109 communicating with the inlet passage 105 at its inner end, and with a circular manifold 110 which is rotatable with the crossbeam 108 at its outer end.
  • the supply manifold 110 delivers coolant to the various coolant supply pipes of the wheel 100.
  • the support shaft 16 is further extended to the right by an intermediate solid section 111 which joins a second integral crossbeam 112.
  • the crossbeam 112 supports a circular hollow coolant discharge manifold 113 which communicates by a duct 114 with the hollow terminal bearing end 115 to form a dscharge outlet for spent cooling fluid from the discharge manifold 113.
  • the terminal bearing end 115 of the shaft 16 is supported for rotation in the right hand bearing sleeve 17 of the right hand supporting stanchion 18.
  • the coolant tubes in the casting ring 'body 102 and in contact with the liner 103 are segmental arcuate tube flights, each flight being independently supplied with coolant from the supply manifold 110.
  • each flight being independently supplied with coolant from the supply manifold 110.
  • four consecutive flights in quadrants of approximately 90 complete one consecutive annular series of flights.

  • the arcuate segments of the coolant tubes are located in direct contact with the liner 103 for maximum heat exchange relation.
  • the material of the ring body may be of such material as to provide maximum strength as compared with materials which must fulfill high heat exchange requirements. It is further to be noted that, by the provision of multiple segmental coolant tubes, the body 102 is not subjected to the intense temperature changes which produce the thermal ratcheting phenomenon hereinabove discussed.
  • an outer left hand side quadrantal flight of tubing in contact with the liner 103 is supplied with co0lant fluid from the supply manifold 110 by supply pipe 120.
  • an inner side tubing flight which is in contact with the liner 103 on the right hand side of the wheel 100 is supplied with coolant fluid from the supply manifold 110 by pipe 121.

  • an adjustment of the coolant flow can be provided by the manual valves indicated at 132. Obviously, such facility of adjustment of fluid flow in relation to the heat exchange requirements will effect not only the quality of the cast bar, but also an economy in operation.
  • coolant flow regulated by the valves 132, supplies coolant to the tube flights adjacent the liner 103.
  • the coolant enters the tube flights and flows along their length, transferring the heat conducted through the liner 103 from the walls of the tube flights by forced convection.
