Description
Technical field
The present invention relates to a kind of crystallizer of used in aluminium alloy casting cooling water angle adjustable, belong to the aluminum alloy semi-continuous casting technical field.
Background technology
The direct-cooling type semi-continuous casting is the main mode of producing aluminum alloy round ingot and slab ingot at present, and crystallizer is one of core frock of aluminum alloy semi-continuous casting.In the production process, aluminium liquid retrains shaping in crystallizer, moves down with dummy bar head, and cooling water is ejected into thorough cooling ingot casting on the scull at a certain angle in the crystallizer then.Cooling water is ejected into ingot casting with different angles, and the cooling effect of generation is also different, and when cooling water became 15 °～30 ° with the ingot casting center line in the general crystallizer, the cooling effect that is ejected into the ingot casting surface was stronger.
During the aluminium alloy D.C.casting was produced, different cultivars aluminum alloy casting technique characteristic was also different, and the aluminium alloy casting of low-alloy content often adopts higher intensity of cooling, thereby enhanced productivity to improve casting speed; The aluminium alloy casting of high alloy content then adopts lower intensity of cooling, and reduces casting speed, thereby improves casting success ratio to reduce the internal stress that ingot casting produces in the casting process.For a long time, to be ejected into the angle of ingot casting be immutable to cooling water in the single crystallizer, and the adjustment intensity of cooling realizes that through regulating cooling water flow/hydraulic pressure its adjusting range is limited often.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of crystallizer of used in aluminium alloy casting cooling water angle adjustable is provided.
The object of the invention is realized through following technical scheme:

Further; The crystallizer of above-mentioned used in aluminium alloy casting cooling water angle adjustable; Wherein, The two ends that two ends and the left and right sides leptoprosopy cooling pipe of face cooling pipe are rolled in said front and back are tightly connected with an end of sliding shoe respectively, and the other end of sliding shoe is provided with fan-shaped boss, and the covering of the fan boss is assemblied in the scalloped recess of fixed block corresponding with it.
Further, the crystallizer of above-mentioned used in aluminium alloy casting cooling water angle adjustable, wherein, the aperture of said cooling water hole is ∮ 2～4mm, pitch of holes is 7～11mm.
Substantive distinguishing features and obvious improvement that technical scheme of the present invention is outstanding are mainly reflected in:
1. the present invention sets up cooling pipe below the crystallizer body, and cooling pipe and body water cavity are used soft pipe connection, on cooling pipe, design cooling water hole, and cooling water hole is separated with crystallizer body water cavity;
2. unique design fixed block and sliding shoe, fixed block is installed on four bights of crystallizer body, sliding shoe links to each other with the cooling pipe termination; One end sealing cooling pipe; The other end cooperates with fixed block, and there is a fan-shaped boss sliding shoe termination, is assemblied in the fixed block scalloped recess; Make cooling pipe to rotate, thereby reach the purpose that changes the cooling water spray angle around ingot casting water breakthrough point;
3. the cooling water hole design is on the cooling pipe below the body, and cooling pipe rotates in fixed block through sliding shoe, makes crystallizer cooling water hole spray angle in 20～70 ° of scopes, to change.

The specific embodiment
Like Fig. 1, shown in Figure 2, the crystallizer of used in aluminium alloy casting cooling water angle adjustable comprises body 3 and loam cake 4; Loam cake 4 is connected on the body 3 through bolt 1; And by sealing strip 2 sealing, body is provided with cooling water cavity, and the front and back of cooling water cavity are rolled face and are separately installed with and roll face cooling pipe 12; Rolling face cooling pipe 12 is connected with the face cooling water cavity of rolling; The left and right sides leptoprosopy of cooling water cavity is separately installed with leptoprosopy cooling pipe 14, and leptoprosopy cooling pipe 14 is connected with the leptoprosopy cooling water cavity, and four bights of body bottom surface are fixed with fixed block 9 through bolt 10 respectively; The two ends of face cooling pipe 12 are rolled in front and back and the two ends of left and right sides leptoprosopy cooling pipe 14 flexibly connect through sliding shoe 11 fixed blocks 9 corresponding with it respectively; Front and back are rolled on face cooling pipe 12 and the left and right sides leptoprosopy cooling pipe 14 and are distributed with cooling water hole 8, and the aperture of cooling water hole 8 is ∮ 2～4mm, and pitch of holes is 7～11mm.
During concrete the application, before the beginning aluminum alloy semi-continuous casting, evenly smear one deck lubricating oil, dummy bar head is risen to the inner body wall lower edge, constitute a hemi-closure space at crystallizer body 3 inwalls; Cooling water pipeline is connected with water inlet tube head 13; Flow with less supplies water in crystallizer; Cooling water is through connecting tube head 6 and being connected flexible pipe 7 and entering into and roll face cooling pipe 12 and leptoprosopy cooling pipe 14, after undue water plate 5 distribution, is ejected on the dummy bar head by cooling water hole 8 again.Begin cast aluminum melt in the crystallizer cavity after ready; Dummy bar head begins to move down with less speed when melt liquid level rises near the inner body wall center line; Receive the secondary cooling effect of cooling water behind the ingot casting disengagement crystallizer body of partial coagulation; Strong heat exchange takes place in ingot casting and cooling water, the complete gradually solidification forming of whole ingot casting.After casting gets into the stabilization sub stage, increase cooling water flow and casting speed gradually,, ingot casting stops casting after reaching Len req.
Crystallizer of the present invention can change the cooling water spray angle.When the big intensity of cooling of needs; Before the casting beginning, covering of the fan boss 15 is positioned scalloped recess 16 tops; Cooling water hole and the axial angle of crystallizer that roll on face cooling pipe 12 and the leptoprosopy cooling pipe 14 this moment are 20 °; Cooling water is ejected into the ingot casting surface in the casting process, and it is less to rebound, thereby can obtain bigger intensity of cooling; When the less intensity of cooling of needs; Before casting beginning with covering of the fan boss 15 along scalloped recess 16 to lower slider, and be positioned scalloped recess 16 bottoms, cooling water hole and the axial angle of crystallizer that roll on face cooling pipe 12 and the leptoprosopy cooling pipe 14 this moment are 70 °; Obtain bigger cooling water spray angle; Cooling water is ejected into the ingot casting surface in the casting process, and it is more to rebound, thereby can obtain less intensity of cooling.
What need understand is: the above only is a preferred implementation of the present invention; For those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
