Definitions

  • ABSTRACT A twin-belt continuous metal casting machine is described having a pair of removable core assemblies each comprising coolant applicators and back-up rollers for supporting and cooling the respective casting belts. These removable core assemblies are fitted into large open channels in the respective upper and lower belt carriages adjacent to the region in which the mol- 6 Claims, 4 Drawing Figures SHEET 1 [IF 2 PAIENIl-Imum 3M4 DESCRIPTION The present invention relates to a twin-belt continuous metal casting machine having removable core assemblies comprising the coolant applicators and backup rollers for the two casting belts.
  • the invention is embodied in a twin-belt continuous metal casting machine and is an improvement in twinbelt machines as shown in US. Pat. NOS. 2,604,235; 2,904,860; 3,036,348; 3,041,686; 3,123,874; 3,142,873; 3,167,830; 3,228,072; and 3,310,849.
  • the finned back-up rollers which support and guide the two casting belts along opposite sides of the casting region and the coolant applicators which apply liquid coolant to the reverse surface of each belt near the casting region are incorporated into removable core assemblies.
  • the transverse beams for each removable core assembly are provided by rigid conduit header sections which are quickly disconnected, coupled to pipe lines extending to the large supply manifolds in the machine.
  • the resultant core assemblies are strong, rigid and compact for ease of insertion into or removal from the metal casting machine.
  • this separate pre-assembly of these components facilitates their accurate assembly and alignment before the resulting core unit is inserted into the machine.
  • the alignment of each component can be readily checked with precision because the core assembly is set up by itself where all of the components are directly accessible to and can be viewed by the technicians without mechanical interference from other parts of the machine. Straight edges and optical alignment gauges can be employed.
  • FIG. 1 is a cross-sectional view taken through a twinbelt continuous metal casting machine incorporating the removable core assembly of the present invention
  • FIG. 2 is a partial elevational view of the machine of FIG. 1, taken along the plane 22 in FIG. 1 looking toward the left and showing the outboard ends of the two belt supporting carriages, with portions being broken away to show the structural components;
  • FIG. 3 is a plan sectional view being taken along the line of plane 33 in FIG. 2, looking downwardly;
  • FIG. 4 is an enlargement of a portion of FIG. 2 showing the structural beam members being provided by rigid conduit headers for supplying coolant to the coolant applicators.
  • the molten metal is solidified in a casting region C defined by the supporting parallel moving surfaces of upper and lower endless flexible casting belts 12 and 14.
  • These two casting belts are supported and driven by means of an upper and a lower carriage, as indicated in FIGS. 1 and 2 at U and L, respectively.
  • the two casting belts l2 and 14 are driven at the same speed from left to right as seen in FIG. 2 along adjacent casting region C with the molten metal being carried along between them as it solidifies.
  • the upper carriage includes a frame 16 supporting two main rolls l8 and 20 (FIG. 2) around which the upper casting belt 12 is revolved.
  • the lower carriage L includes a frame 22 supprting two main rolls 24 and 26 around which the lower casting belt 14 is revolved.
  • the lower carriage frame 22 projects in cantilevered relationship from the main structural support 28 of the machine.
  • This structural support 28 has an upstanding back frame 30 which serves to support the upper carriage U.
  • the back frame 30 carries a lift arm 32 by means of a fulcrum pivot located at 33.
  • the front end 34 of the lift arm 32 is pivotally connected at 35 to an upright portion 36 of the frame 16 of the upper carriage.
  • the upper carriage U can be raised and lowered by lift means 38 acting upon the rear portion of the lift arm 32.
  • the molten metal in the region C is retained between the belts 12 and 14 by means of a pair of spaced edge dams 39 and 40 (FIG. 1) which revolve about the lower carriage L and move along either edge of the casting region.
  • edge dams may be formed as shown in US. Pat. No. 2,904,860 or 3,036,348, among those listed in the introduction.
  • This molten metal imposes a heavy loading on the belts l2 and 14.
  • removable belt supporting and cooling core assemblies 41 and 42 are included in the upper and lower carriages U and L,respectively.
  • Each removable core assembly 41 and 42 is preassembled and can be installed in or removed from its respective carriage as a unit.
  • each of these large channel openings extends the major part of the length of the respective carriage U or L, and is positioned adjacent the casting belt near the casting mold region C. That is, the large channel opening recess 43 in the upper carriage extends the major length of the region between the rolls 18 and 20 along the'lower side of this upper carriage. Similarly, the large channel opening recess 44 in the lower carriage extends the major length of the region between the main rolls 24 and 26 and is located on the upper side of the lower carriage where it faces the mold region.
  • the upper and lower removable core assemblies 41 and 42 are of modular design and can be interchanged. They each include a base plate 46 and a plurality of transverse beams 48 formed by rigid coolant supply condiuts of rectangular cross section, as seen most clearly in FIG. 4.
  • the long axis of the rectangular section of these conduits 48 extends in the vertical plane to provide stiffness to resist the load of the molten metal in the casting region C. As shown in FIG. 4, these conduit beams 48 are regidly secured to the base plate 46 as by machine screws 50.
  • liquid coolant is applied at high velocity and evenly distributed over the reverse surfaces of the casting belts l2 and 14 by means of coolant applicators 52 (FIG. 4) to form a high velocity layer of coolant travelling along the belt.
  • the coolant is supplied under pressure into the header passageways 54 within the respective conduits 48 and issues through nozzles 56 directed toward the applicators 52.
  • Part of the coolant is scooped away from the coolant layer on the belt by a leading edge 58 of the applicator.
  • the applicators 52 are secured to and supported by therigid conduit beams 48.
  • FIG. 3 shows these applicators extending across the full width of the core assembly 42.
  • the reader may refer to U.S. Pat. No. 3,041,686, mentioned above.
  • Both casting belts I2 and 14 are directly supported along the mold region C by a plurality of back-up roller assemblies 60.
  • These roller assemblies include multiple narrow circumferential fins 62 engaging the reverse surface of the belt, which do not restrict the liquid coolant layer flowing along these reverse surfaces.
  • Each of these roller assemblies is divided into three segments 60-l, 60-2 and 60-3, so as to span the full width of the belt carriage. This segmented back-up roller arrangement reduces the distance between supports thus drastically reducing deflection of each segment 60l, 60-2 and 60-3 roller without increasing the diameter of the shaft 64 or fin 62 and also allows close spacing of the rollers to provide continuous support for the casting belt.
  • the center segments 60-2 of the back-up roller assemblies and the inner ends of the outer segments 60-l and 60-3 are supported by a pair of longitudinal stringers 66 extending the length of the core assembly. These stringers are attached to the conduit beams 48 by means of triangular gussets 68.
  • FIG. 4 In FIG. 4 are shown the mounting caps 70 which secure reduced diameter shaft portions 72 of the roller assemblies to the stringers 66.
  • the outer ends of the two outer roller segments 60-1 and 60-3 are supported by longitudinal rails 74 which extend along the sides of the removable core assemblies 41 and 42. Reduced diameter shaft portions 72 (FIG. 1) are received into mounting holes in these side rails 74.
  • the base plates 46 are fastened to the frames 16 and 22 by large machine screws 76 (FIG. 2).
  • large machine screws 76 FIG. 2
  • clamps 78 FIG. 1
  • These clamp members 78 are attached by heavy machine screws (not shown) to the frames of the belt carriages.
  • Each core assembly is located in position in its carriage by means of vertical keys 80, as shown in FIG. 3, engaging between the ends of the side rails 74 and the carriage frame 22.
  • plug-in disconnect couplings 88 are fitted with 0 rings (not shown) and can be easily slipped into sockets 91 in the strainer ducts 87 and into the transition sections 90 thus facilitating installation and removal of the core assembly.
  • the upper carriage is raised to open the casting section C.
  • the casting belt is removed from the respective carriage U or L, and thus the core assembly is fully exposed and accessible for removal.
  • a twin-belt continuous metal casting machine having casting belts revolving around two belt supporting carriages for defining a casting region between the belts, and wherein each of the carriages has a frame with main rolls located at opposite ends of the carriage for revolving the casting belt around the carriage, the invention comprising:
  • a removable core assembly for insertion into each belt carriage including a plurality of coolant applicators having coolant conduits extending transversely across the core assembly for applying liquid coolant to a castingbelt and a plurality of finned back-up rollers extending transversely for supporting and guiding the casting belt adjacent to the casting region,
  • each of the carriages defining a large channel opening on the sideof the carriage facing toward the casting region for receiving the core assembly inserted therein
  • each of said coolant conduits means for removably connecting each of said coolant conduits to a supply of liquid coolant in the casting machine
  • said coolantconduits are rigid and form transverse stiffening beams in the removable core assembly.
  • longitudinal stringers and side rails are included in the removable core assembly secured to said coolant conduits,
