Definitions

  • the cooling apparatus includes a wedge shaped cooling means positioned adjacent the entry end of the mold between the casting wheel and a support wheel by which the band is supported at the entry end of the mold.
  • the wedge shaped cooling means serves as a means for directing a coolant along the surface of the band in a path away from the entry end of the mold.
  • the cooling apparatus also includes'a plurality of additional cooling means positioned along the length of the peripheral groove closed by the band for directing a coolant against the surface of the band in paths which are substantially perpendicular to the surface of the band.
  • the position of the wedge shaped cooling means and the path of a coolant from the wedge shaped cooling means along the surface of the band serve not only to cool the band adjacent the entry end of the mold but also to prevent splashing of coolant into the entry end of the mold or onto molten metal entering the entry end of the mold.
  • This invention relates to mold cooling and more particularly to a cooling apparatus for cooling a mold substantially immediately after molten metal is received in the mold.
  • a difliculty encountered in the prior art in the cooling of a mold substantially immediately after molten metal is received in the mold is that even though it has provided initial cooling of the molten metal which is adjustable independently of subsequent cooling of the molten metal, cooling adjustments during the initial cooling of the molten metal to meet varying operating conditions have been difiicult to achieve.
  • a further difliculty in the prior art is that where a mold is formed by the peripheral groove in a casting wheel and a band closing the peripheral groove orby another mold arrangement in which molten metal is received in one end of the mold and passes as cast metal from the other end of the mold, the cooling of the mold substantially immediately after molten metal is received in the mold has generally. been accomplished only at the risk of an explosive reaction between the coolant for the mold and the molten metal.
  • the invention disclosed herein overcomes these and other difficulties encountered in the prior art in that it provides for the controlled initial cooling of a molten metal in a mold by a coolant from substantially the time that the molten metal enters the mold until the initial cooling of the molten metal is completed without the risk of an explosive reaction between the coolant and the molten metal. Moreover, by providing for the cooling of the mold substantially immediately after molten metal is received in the mold, the invention not only provides for complete control of the initial cooling of the molten metal in the mold but also insures that the mold is not damaged by the heat of the molten metal.
  • the invention avoids the difiiculties encountered in the prior art by directing a plurality of independently adjustable coolants in sequence against the mold to provide for the controlled initial cooling of the molten metal and by directing one of the coolants against the mold adjacent the entry end of the mold. That coolant directed against the mold adjacent the entry end of the mold serves as an entry coolant and the entry coolant is directed against the mold in a path which causes the coolant to move along the surface of the mold in a direction away from the entry end of the mold. The path of the entry coolant prevents the splashing of this coolant into the entry end of the mold or the splashing of this coolant onto the molten metal during the pouring of molten metal into the entry end of the mold.
  • the path of the entry coolant serves to prevent the other coolants from reaching the entry end of the mold.
  • the entry coolant and the other coolants in the plurality of independently adjustable coolants provide for the controlled initial cooling of a molten metal in a manner not possible in the prior art without the risk of an explosive reaction between a coolant and the molten metal.
  • FIG. 1 is a front elevational view of a casting machine which embodies the invention disclosed herein;
  • FIG. 2 is an enlarged detailed side elevational view of a plurality of wedge members for directing entry coolant against a mold adjacent the entry end of the mold;
  • FIG. 3 is -a sectional view of one of the plurality of Wedge members shown in FIG. 2 taken in line 3-3 in FIG. 2.
  • the invention disclosed herein is best understood in terms of a casting machine C, such as that shown in FIG. 1, having a casting wheel 10 and an endless band 11 positioned against the periphery of the casting wheel 10"by a plurality of support wheels 12, 12', and 12".
  • the casting wheel 10 includes an annular member 13 with a peripheral groove 14 which is closed by the band 11-to provide a mold M having an entry end A at which a molten metal 15 is received from a crucible 16 and an exit end B from which a cast metal 17 passes.
  • cooling of the inner periphery 18 of the annular member 13 is ac- 18 of'the annular member 13 through a plurality of nozzles 19 from a plurality of chambers 20 and 21 to which coolant is supplied through supply tubes 22 from a main supply line 23,.
  • the sides 24 of the annular member- 13 are cooled by coolant direct against the Sides 2 10f the annular member 13 through a plurality of nozzles 25 item atplurality of arcuate tubes 26 to which coolant is supplied through supply tubes 27 from he m in upply line 23.
  • videsan efiective means for controlling the rates at which a molten metal 15 in the mold M is cooled.
  • the prior art has not provided for cooling the band 11 adjacent the entry end A of the mold M without the risir of coolant entering the entry end A of the mold M or being splashed on the molten metal 15 as the molten metal 15 enters the entry end A of the mold M.
  • the prior art has failed to cool the band 11 in a casting machine C substantially immediatelyafter molten metal is received in, the mold M in order to avoid this risk of coolant entering the mold M or splashing on the molten metal 15, damage to the band 11 from the heat ofthe molten metal 15 has frequently resulted.
  • the cooling of the band 11 in a casting machine is representative of the difficulties' encountered in the prior art in the cooling of a mold.
  • the casting machine C is merely representative of a mold arrangement and that the cooling apparatus R is merely representative of a variety of cooling arrangements in which the invention disclosed herein may be embodied.
  • the cooling apparatus R for cooling the band 11 as taught herein comprises a plurality of cooling means 30, 31, and 32 arranged in sequence between the entry end A of the mold M and that point C along the arcuate path followed bythe molten metal 15 as it moves with the mold M at which it generally desired that the initial cooling of the molten metal 15 be substantially completed.
  • the cooling means 30 serves as an entry cooling means for cooling the band 11 substantially immediately after molten metal 1 is received in the mold M at the entry end A of the mold M.
  • the entry cooling means 30 includes a plurality of wedge members 33 mounted in parallel on a supply tube 34 which extends between the casting wheel and the support wheel 12 that supports the band 11 at the entry end A of the mold M.
  • Each wedge member 33 has parallel sides 35 and 36. spaced apart and joined by a nozzle plate 37 and Wall plates 38,, 39 and 40 so as to define a coolant receiving chamber 41 through which the supply tube 34 extends and into which a coolant passes through a plurality of apertures 42 in the supply tube 34 from the main supply line. 23.
  • each wedge member 33 is inserted into the space between the casting wheel 10 and the support wheel 12 with an apex 43 of each wedge member 33 adjacent the line of tangency of the support wheel 12 with the casting wheel 10 and with the nozzle plate 37 of 7 each wedge member 33 extending downwardly adjacent the band 11 at the entry end A of the mold M.
  • nozzle plate 37 is a substantially solid block having a plurality of coolant discharge channels 44 extending downwardly through it in a direction which results in the discharge of jets oi coolant from a coolant receiving chamher 41 downwardly'along the surface of the band 11.
  • each wedge member 33 serves to direct jets of coolant against the band 11 adjacent the entry end A" of the mold M in paths which cause the coolant to move along the band 11 away from the enry end A.
  • the cooling means 31 and the cooling means 32 are arranged in sequence adjacent the arcuate path of the molten metal as it moves with the mold M from the entry cooling means 30 to the point C.
  • Each cooling means 31 and 32 is an arcuate tube 44' positioned adjacent the band 11 and having a plurality of nozzles 45 positioned along its length for directing jets of coolant ing means 31 and 32. Moreover, the path of coolant from.
  • the entry cooling means 30 is such that coolant directed against the band 11 by the entry cooling means 30 moves along the band 11 away from the entry end A of the mold M and when this coolant reaches that coolant being directed against the band 11 by the cooling means 31, the coolant being directed against the band 11 by the cooling means 31 is moved along the band 11 away from-the entry end A of the mold M even though it is being directed against the band 11 in a path substantially perpendicu? lar to the band 11.
  • the entry cooling means 3.0 not only provides a means for directing coolant against the band 11 immediately adjacent the entry end A of the mold M but also provides a means for providing a flow of coolant along the band 11 away from the entry end A of the mold M which moves other coolants from the cooling means 31 and the cooling means 32 away from the entry end A of the mold 11.
  • the entry cooling means 30, with the cooling means 31 and the cooling means 32 provides three independently adjustable cooling zones through which the molten metal 15 passes as the molten metal 15 I moves with the mold M between the entry end A of the, mold M and the point C.
  • the supply tube 34 has a valve 50 positioned therein and the main supply linet23 has a main supply valve 51 positioned therein, and it will be understood that adjusting of the valve 50 and of the valves 46 and 47 when the main supply valve 51 is open will adjust the coolant from a coolant source (not shown) directed against the band 11 in sequence by the cooling means 30, 31 and 32 to provide for substantially any desired initial cooling of the molten metal 15 between the entry end A of the mold M and the point C Moreover, the entry cooling means 3.0 provides a convenient means for pre-cooling the band 11 prior to molten metal 15 entering the mold M.
  • Such a pre-cooling of the mold M is particularly desirable when it is required that coolant be directed against the band 11 under relatively high pressures to cool molten metal 15 in the mold M since such pressures in the absence of the heat of the molten met-a1 15 in the mold M create a vapor which could enter the mold M in spite of the action of the entry cooling means 30.
  • the flow of coolant'prior to molten metal 15 entering the mold M is limited to the entry cooling means 30 by closing the main supply valve 51 and by supplying coolant to the entry cooling means 30' with a by-pass line 53 through a valve 54 which provides a coolant pressure less than that provided by the valve 50.
  • a check valve 55 prevents coolant from entering the main supply line 23 through the supply line 34 even though the valve 50 is open.
  • the band 11 adjacent the entry end A of the mold M is cooled only by coolant at less than operating pressure flowing along the band 11 away from the entry end A of the mold M.
