Abstract

The present invention includes a crystallizer mounted on the dummy head on the dummy seat, the upper portion of crystallizer is equipped with flow distribution plate which can possess hot top action. It is characterized by that the bottom portion of the described flow distribution plate is equipped with more than two fow-distributing holes correspondent to every crystallizer. The adoption of said invented equipment can produce aluminium alloy flat ingot, can solve the flow equalization problem in the course of casting process, the cast aluminium ingot does not produce crack, so that the same-level hot top casting process can be adopted in the production of aluminium alloy flat ingot.

Description

Horizontal casting equipment for aluminium alloy flat ingot
The invention belongs to a kind of hot-top casting device that is used for the flat ingot casting of Birmasil, also be applicable to the ingot casting of other complex geometry of casting.
Traditional direct-cooled (DC) casting technique device therefor as shown in Figure 1, be provided with flow table (1) and shunting funnel (3) on crystallizer (4) top that is loaded on the mould platform, the crystallizer bottom is provided with the dummy bar head that is contained on the dummy ingot seat, before the casting, the mould platform, the dummy ingot seat is set up the casting well, dummy bar head is gone up, it is stretched into form complete mold in the crystallizer, during casting, metal aluminium liquid flows into crystallizer from the shunting funnel, logical water quench, dummy bar head moves to the casting downhole with certain speed, the aluminium ingot of cooling forming in the crystallizer is pulled out, reach certain-length and stop to open the mould platform and hanging out ingot casting for aluminium liquid and cooling water.This process equipment weak point is to control the level of DC crystallizer inner metal liquid face well, liquid level is crossed the low ingot casting surface of can causing and is formed cold shut, can produce leakage aluminium when serious, the too high degree of depth that can increase the weight of ingot casting surface deviation knurl again very easily causes the ingot casting surface to draw trace, drawing crack.Adopt the hot direct casting fabrication technique of same level can solve this class problem at present, the used Casting Equipment of hot direct casting fabrication technique is as shown in Figure 3: promptly crystallizer (4) upper shed place be provided with refractory thermal insulating material make heat top (10), the heat top is provided with recessed shunting disk (8), corresponding each crystallizer internal cavity centre, shunting disk bottom is provided with a tap hole (11), had after the hot top, the level of crystallizer inner metal liquid face just is easy to control, so the ingot casting internal soundness that the hot direct casting fabrication technique of same level is produced is good, whole ingot structure is even, good mechanical property, the ingot casting smooth surface, and since hot direct casting make and cancelled funnel, thereby can cast the more tiny ingot casting of specification on the one hand, simplify technology on the other hand, improve production efficiency.But this technology can not be directly used in the production slab ingot, because the longitudinal length of slab ingot is greater than transverse width, in the direct-cooled casting of tradition, produce slab ingot and will in direct-cooled crystallizer, put the ship shape shunting funnel (3) of the vertical uniform liquid stream of energy, just can cast out the ingot casting that does not have crackle, and can not place the shunting funnel in the hot direct casting fabrication technique of same level device, so the casting of present aluminium alloy flat bloom still can only be adopted traditional direct-cooled technology.
Thereby aiming to provide a kind of shunting funnel of not establishing, the present invention also can have the current-sharing effect can produce the horizontal casting equipment for aluminium alloy flat ingot of qualified slab ingot to metal aluminium liquid.
The technical scheme that realizes above-mentioned purpose is (Fig. 5,6 in conjunction with the embodiments): the present invention includes crystallizer (4), crystallizer bottom correspondence is provided with the dummy bar head that is contained on the dummy ingot seat, the crystallizer top is provided with the shunting disk (8) of making, having held concurrently the effect of hot top with refractory thermal insulating material, the shunting disk bottom is provided with the tap hole (11) that communicates with crystallizer internal cavity, it is characterized in that: corresponding each crystallizer internal cavity in described shunting disk (8) bottom is provided with the tap hole (11) that is no less than two.
The present invention is provided with two or more tap holes at corresponding each crystallizer internal cavity in the shunting disk bottom of the hot-activity effect of having held concurrently, changed corresponding each crystallizer internal cavity of the hot direct casting fabrication technique of same level device shunting disk in the past only is provided with a center tap hole in the centre structure, can tap hole evenly be set according to the geometry of ingot casting like this, reach the purpose of mean allocation metal liquid stream, the present invention had both utilized the advantage of the hot direct casting fabrication technique of same level, solved equal flow problem again with this explained hereafter aluminium alloy flat ingot casting, when adopting this device casting aluminium alloy flat bloom, the liquid cave can be very not dark in the crystallizer, liquid cave shapeliness, the slab ingot that casts out had both had all advantages that ingot casting is made in the hot direct casting of same level in the prior art, be not prone to crackle again, also can be used for casting the ingot casting of other complex geometry simultaneously.

The embodiment explanation:
This example is arranged 12 crystallizers and is located on the same mould platform, corresponding each crystallizer in mould platform below is provided with the dummy bar head that is contained on the dummy ingot seat, each crystallizer top is provided with refractory thermal insulating material makes, and the heat that has recessed shunting disk 8 pushes up 10, the cross section of crystallizer is a flat, shunting disk bottom in hot top evenly is provided with two tap holes 11 in corresponding each flat crystallizer longitudinal length direction, and tap hole is up-small and down-big tubaeform, and this shape is more conducive to shunting.
Cooling water seam 12 on this routine flat crystallizer is that vertical cooling water seam width is greater than horizontal cooling water seam width, its width ratio is 4/3: 1, this is because the slab ingot longitudinal side wall is longer than lateral sidewalls, if vertical, horizontal cooling water seam width is equally wide, slab ingot longitudinal side wall cooling velocity will be less than the cooling velocity of lateral sidewalls, influence ingot quality, so on vertical outer wall, provide more cooling water that cooling velocity is everywhere reached unanimity.
This example is provided with annular graphite annulus lining 9 in upper shed place of crystallizer inwall, can further improve ingot surface quality.
The present invention also can be provided with the tap hole more than 3 according to the shape of crystallizer cross section in the shunting disk bottom of corresponding each crystallizer.
