The specific embodiment
Referring to Fig. 1 and Fig. 2, cast wheel 10 is around trunnion axis 12 rotations.This is taken turns has annular element 14, and this annular element 14 has around the fixing a plurality of spouts 16 of circumference.Although can adopt the spout of any suitable quantity to adapt to the restriction of ingot mould, for illustrative purposes, in Fig. 2, show 12 spouts.Feed launder 18 is transported to wheel 10 with motlten metal (not shown).Single successive molten metal flow pours in the edge of opening 22 of annular element 14 from the outflow tip 20 of feed launder.Each spout 16 forms an opening in the edge of wheel, and metal is imported to downwards in the ingot mould 24.Wheel and spout are preferably one-body molded, as independent iron casting.Also selectively, wheel and spout are made respectively, are installed together then, so that change easily and keep in repair.
Mould 24 is in a string identical ingot mould, and it is by drag-chain conveyer carrying by cast wheel 10.When cast wheel was rotated, along with mould 24 moves along carrier, spout was corresponding with mould 24.The rotary speed of wheel and the space rate of carrier are mated mutually, thereby each casting spout 16 is followed the tracks of this mould 24 at corresponding mould 24 by taking turns following time.When mould just in time was positioned at the below of wheel axis 12, spout 16 suitably extended in its corresponding mould 24.Feeding molten metal all can be controlled to the speed of cast wheel, the speed of carrier and the rotary speed of wheel, so that motlten metal reaches the desirable degree of depth in mould, no matter and therefore how many delivery rates of motlten metal is, all can make the ingot bar of constant height.
Referring to Fig. 3 to Fig. 7, the annular element 114 of cast wheel 110 has 12 and is attached to spout 16 on the annular element 114 by bolt, and their contact-making surface 126 is pressed against on the annular element 114 like this.If wearing and tearing or damaged, individually or a whole set ofly change spout 116 easily by the bolting system.
Yet, most of cast wheel of the prior art is used the wheel body with tympanum structure, the spout that its peripheral region with relative two ends at tympanum, tympanum connects, and the present invention preferably has the tympanum main body, it comprises the anchor ring of a substantially flat, and spout is outstanding from the one side/face of this anchor ring.
Each spout is all round the circumference setting and the moulding of annular element, so as along with motlten metal when chute flows to mould by spout, under the situation of the exposed surface area that does not increase fluid velocity and motlten metal, motlten metal is filled into the mould from chute.
Below, in the context in as shown in Figure 5 and Figure 6 orientation, use upper and lower and similar word to describe spout 116, that is, and about the spout orientation, as spout 117 (among Fig. 4) in the bottom of cast wheel and be positioned this and be used for from then on flowing out motlten metal.
Each spout 116 has an inclined base 128 and pair of sidewalls 130.Have face 126 on the sidewall 130, it fixedly is contacted with the annular element 114 of wheel.Each sidewall 130 all has an edge of opening 135, is used to contact the motlten metal from chute, and the initial part 137 of moulding sidewall is so that when it was positioned on the wheel, the initial part 137 of adjacent sidewall was substantially parallel.Like this, sidewall contiguous or adjacency has an initial part, and it has and minimal contact angle degree from the metal flow of chute.Like this, thus the effect guiding that plays the fluid partitioning device in abutting connection with sidewall of contiguous spout enters the fluid of cast wheel arrives separately spout.
The sidewall 130 of spout is the spill of extending towards spout base 128.The spill of sidewall makes base and sidewall link together, and does not need the fillet of stipulating and be joined together between the two, thus, has reduced turbulent flow wherein when motlten metal enters spout.134 (promptly from tops to the below) are convergents to sidewall 130 from edge of opening 135 to the port of export relative to each other.
Go into the turbulent flow of the motlten metal stream in the wheel and minimize in order to use the gravity flow concentrated flow, making the inclined-plane of the spout in the zone that contacts with motlten metal stream is special parabolic shape.The base of spout preferably 138 has convex curvature part and 140 has recessed curvature part in its underpart on top.In base, produced waveform like this, so that the motlten metal stream that leads more smoothly and enter spout.This bossing 138 preferably extends from the initial contact area of base with the motlten metal that enters.
Therefore, base wall 128 starts from its arrival end (top) 132, relatively 45 ° (preferably in scope of 35 °-55 °) of the about inclination of horizontal plane.Then, base wall approximately is being positioned at the spout base wall midway downwards towards vertical direction and bending reaches relative horizontal plane up to it to be approximately 70 ° (preferably in scopes of 60 °-80 °); And then, base wall is to the horizontal direction bending, up to it is level substantially at its port of export (bottom) 134.
The top 138 of the convex shape of base or rear wall have approximate parabolical shape, and its intrinsic curvature with the free sinking of the motlten metal of gushing out from chute matches.The position of chute does not show in Fig. 3 or Fig. 4.Use has the curvature of determining top 138 from the horizontal component velocity of the speed of the metal of chute outflow in normal casting speed.
The bottom 140 of the spill of the rear wall 128 of spout has the shape that the metal that leads again glossily becomes horizontal flow.Horizontal flow is favourable, because it has minimized splashing of metal, has minimized more liquid metals and has been exposed in the air, has minimized disorder and oxide and the dregs formation thing in the mould.
Spout is positioned at the end of mould as far as possible, and metal flows into the mould from this end.
In this embodiment, in order to minimize the disorder of decline metal, dirty along with metal flow, the kinetic energy of transferring on the liquid metals by potential variation is minimized.Be lower than the chute relevant because chute is supplied with the bottom of groove with traditional spout, thus the height difference of supplying with between the trench bottom at mould bottom and chute be minimized, thereby minimized the kinetic energy that is sent on the decline metal.Drop to metal in the spout along an approximate parabolical curve and led again along an opposite approximate parabolical curve subsequently, thereby flow to from spout on the direction of level of approximation.This has minimized disorder when motlten metal enters mould.And spray fluid between allowing radially to export and enter into mould, along with fluid is ejected into die wall and the interruption that causes metal flow is compared with disorderly situation, metal flow in the invention described above is directed to Horizontal Exit again, thereby liquid metals approximately horizontally flows out in the mould and therefore minimized stream disorder when entering mould.Spout is adjacent to an end of mould, and liquid metals flow in the mould away from an end of the nearest mould of spout, thereby for liquid metals maximized mobile distance is arranged, and be that the adverse current of motlten metal minimizes.
Fig. 8-Figure 10 has set forth another embodiment that is used for spout 300 of the present invention.As the embodiment of Fig. 5-Fig. 7, each spout all has an inclined base wall 328 and pair of sidewalls 330.Have on the sidewall 330 in the face of edge 326, it fixedly is contacted with the annular element 114 (among Fig. 3) of wheel.Each sidewall 330 all has an edge of opening 335, is used to contact, separate and leads when cast wheel is rotated from the motlten metal stream of chute.The initial part of moulding sidewall, so that when it is positioned on the cast wheel, the initial part of adjacent sidewall (not shown) is in abutting connection with also substantially parallel.Therefore, the initial part of the sidewall in the perpendicular is perpendicular to motlten metal and sidewall, and this sidewall is basically parallel to described metal flow, has the minimum initial contact angle degree with motlten metal stream.
Along with extending from the base 328 of initial part to spout, the sidewall 330 of spout is a spill.The spill of sidewall has allowed base 328 and sidewall not to need the fillet of stipulating and has been joined together, and thus, has reduced turbulent flow wherein when motlten metal enters spout.
In the embodiment of Fig. 8-Figure 10, spout inside has the stream guiding rib in base and sidewall 320,322 respectively, and its further auxiliary and guiding metal flow flows to the outlet of spout.As shown in the figure, these ribs are the curve from the rat of base 328 and sidewall 330 significantly, but also can be to follow the trail of crooked depression profile.The stream guiding rib extends to outlet 334 from the arrival end of spout.
Spout also have from export 334 extend to sidewall in the face of the capping 332 at edge 326.This capping has prevented to be incorporated into the top that motlten metal in the spout sputters sidewall, can motlten metal be incorporated in the mould with controllable mode more.In filling the process of mould, spout falls in export below the liquid metals surface of rising in the mould, has produced the perfusion situation, at this moment, under the situation that does not produce additional surface, following on the surface disorder is dispersed, so has reduced oxide.
The inlet area of each spout all guarantees to make it not caused the liquid lock of liquid lock in wheel.This has also minimized the speed of motlten metal outflow spout.But for desirable flow velocity, it can not overflow to the entrance side that makes metal at wheel for a short time.
Do not have the space between the spout of vicinity in the periphery of wheel, thereby make the interruption from the metal flow of feed launder minimize.
Casting device of the present invention has minimized the generation of oxide in the process of filling mould with high production rate.The loss in head of the bottom from the chute feeder to mould is lowered, and therefore the kinetic energy that is obtained by the decline motlten metal is lowered.Because the sharp metal flow separator between the spout, directly enter opening in the spout from the metal flow of feed launder.
By radial opening, motlten metal is transported in the wheel, but the dirty direction that changed of motlten metal, thus it is from the spout outflow and on the direction of level of approximation.
As above describe and comprised the preferred embodiments of the present invention, but it should be understood that simultaneously, under the situation of inner characteristic that does not exceed technological thought of the present invention or scope, the multiple variation of introducing in can and being provided with in the structure of aforementioned part, transformation, modification or increase.
It should be understood that also the word that uses " comprises " that (or its grammatical variation) and term " comprise " equivalence in specification, and should not be considered to get rid of the existence of other elements or feature.
