Can cast aluminium bar to aluminium water with the casting machine that the present invention relates to.Although any aluminium alloy can both be cast, the aluminium alloy of the most suitable bar casting machine is from association of following Alcoa code designation: 2XXX, 3XXX, 4XXX, 5XXX, 6XXX and 7XXX.Bar casting machine 10 is effective especially for so-called " hard alloy " (2XXX, 4XXX, 6XXX and 7XXX alloy), and a little alloys in limit can not use the continuous bar Casting Equipment and the method for prior art to cast simply, and reason is their longer condensation scope.Common vertical bar casting machine has been equipped with a ferrule (metalhead) device, this device can promote deposite metal and band good contact and in the initial solidification process deposite metal to the good supply of whole casting region cross section.This helps generating the mushy zone of a weak point.Common vertical bar casting machine has the characteristic that whole sides equalization is solidified.And, because the design of cooling jet has been kept band and the good of bar and has been contacted.This all causes generating a kind of high-quality cast rod section product, and its problem relevant with other cast rod section product reduces to minimum, and for example surperficial liquate separates with center line etc.
In appropriate bar forming process, there are several key factors to be controlled.At first, band must begin to enter and contact just energy resistance to deformation with the deposite metal of coming from cast gate 66 stream.If the fluctuation of band or other distortion (being called " warpage " in the prior art) take place, this can produce adverse effect to surface quality.Secondly, when metal bar solidifies, produce the air gap in order to stop between band and metal bar, band must be kept tight the contact with metal bar.The epidermis refuse that this will stop part to solidify.This refuse causes a kind of defective that is called surperficial liquate.
And, pass band from the bar that is solidifying and must have effective heat conduction.This will improve the metallographic quality of bar and reduce some defectives, for example center line separation etc.
When the deposite metal entered bar casting region 100, the design of cooling bar device 70,72 can be resisted the distortion with 12,14, and kept closely contacting with the bar that is solidifying with 14 with 12.Referring to Fig. 8 and 9, cooling bar device 70 (it is similar with cooling bar device 72, so only one of sets forth in detail) is a hollow-core construction, and it has a cooling wall 200 of facing with 12 cooling surface 12b.Cooling fluid (for example water) is introduced conduit 74 from a cooling fluid source (not shown).Although it is also passable that conduit 74 can be installed in diverse location, the conduit 74 shown in the figure is installed in the middle position of cooling bar device 70.About cooling fluid of supplying the 40-60 pound per square inch, and it is filled up by the cavity that wall surrounded 208 that cools off bar device 70.
Cooling fluid withdraws from cooling bar device by the passage 230 (Fig. 8 and 9) that enters the nozzle qualification, then is sucked out by gravity and by means of the vacuum plant shown in Fig. 9 240.Vacuum plant 240 comprises a shell that is fixed on cooling bar device 70 back sides.Produce vacuum by outlet conduit 242 and 244 in vacuum plant 240 inside.Pass through outlet conduit 242,244 with cooling fluid sucking-off from cooling bar device 70 by the vacuum that vacuum feed source (not shown) provides.
In order to stop the band distortion near bar casting region 100 tops, superposed nozzle is made shape as shown in figure 10.Nozzle has spigot surface 250 and horizontal edge 252 of a concave.Distance between the cooling surface 12b of horizontal edge 252 and band must be less than the distance between the cooling surface 12b of spout 223a and band.Optimum distance between the cooling surface 12b of edge 252 and band is ten sixth inches (1/16 ") or littler.One current 254 pass passage 223 and penetrate and form vortex and form liquid lamella 260 from spout 223a, are with 12 just to move thereon, as shown in figure 10.Preferably cooling fluid also must maintain in as shown in figure 10 the zone of nozzle 250 or more, so that by vacuum V of nozzle 250 generations.Because the diameter of the degree of depth of concave spigot surface, nozzle 250, distance between the cooling surface 12b of the edge at edge 252 and band and maintain horizontal plane around the nozzle, so shown in arrow V among the figure,, between band and nozzle 250, produce vacuum for band is inhaled to nozzle.Vacuum pressure withstands band in a flat orientation, so that make the distortion of band reduce to minimum.Vacuum arrow V also draws in Fig. 7 A.
When bar passes casting region, need less vacuum pressure, so the concave spigot surface needn't recessedly get too dark.This can be as seen from Figure 11, and this figure has drawn and has been positioned at the nozzle at cooling bar device middle part.The member that reference number among Figure 11 points to similar to shown in Figure 10 just is with " a " subscript behind reference number.Metal in the bar casting region does not need vacuum before all solidifying just at all, and in fact, because bar size can shrink when solidifying, contacts with bar in order to keep band, needs a normal pressure to force band to be close to and solidifies on the bar.Therefore, as Figure 12 (among Figure 12 to Figure 10 in the similar member that drawn, mark with a subscript " b ") shown in, this figure has drawn and has been positioned at the nozzle of cooling bar device bottom, spigot surface is normally flat, and, on the cooling surface of band, apply a downforce P from current in order to make it to contact by moving belt with the solid bar.Although the nozzle diameter that draws does not change with the diameter of top spout, also can reduce to produce bigger pressure herein.Pressure arrow P also draws in Fig. 7 D.
Preferably, just can change vacuum and effect pressure on tape by changing the degree of depth and the nozzle diameter of guide surface.Like this, vertical bar casting machine 10 just can be used for casting continuously the different-alloy with various setting rates.And, can more effectively control the heat conduction in the casting machine, thereby produce higher-quality casting bar.
The method of the present invention relates to comprises provides a kind of vertical bar casting machine shown in Fig. 1-12, and solidifies and be provided at casting machine inside by the casting surface of band and the deposite metal in the bar casting region that limits of block.
Common vertical bar casting machine has a plurality of advantages with the continuous bar casting machine utensil of prior art.Because casting process is upright, so can use the metal static head device.This metal static head device provides a kind of fabulous deposite metal to rely on the contact pressure of band and the good transportation of deposite metal in the initial solidification process.This helps to make the short as far as possible (see figure 7) of length of mushy zone.Bar solidifies in the two sides equalization, and owing to cool off the bar device, can keep metal and contact with the good of band in whole bar casting region.This helps processing reduces to minimum premium casting a kind of surperficial liquate is separated with center line.Metal tape provides a kind of fabulous heat conducting device, and does not need covering, preheating or lubricated.
Although it is waterborne to concentrate on cast aluminum through the emphasis of this specification, other deposite metal, for example copper, zinc, steel and lead, also available bar casting machine of the present invention and method of the present invention are cast.The present invention has also imagined a kind of usefulness and the present invention relates to the cast metal bar of method processing and the aluminium bar that a kind of usefulness the present invention relates to method processing.
Should recognize provides a kind of vertical bar casting machine and a kind of correlation technique here, and this vertical bar casting machine can be processed into metal bar to the deposite metal, and a kind of relevant metal bar product also is provided.
When the specific embodiment that the present invention relates to was open, those skilled in the art can make progress according to the aim of whole prospectus to the various changes and the replacement of those details.Correspondingly, the purpose of open special scheme, with regard to the invention scope that is about to provide, just explanation as an example, rather than be used for limiting appended claims and any scope suitable with it.
