Abstract
The utility model discloses a hot top for aluminum alloy circular ingot and horizontal casting, comprising a hot top body 1 and a diversion hole 2, which is characterized in that the center of the hot top body 1 is provided with the diversion hole 2 of bottleneck type communicated with the chamber of a crystallizer; the lower end of the diversion hole 2 is provided with a horn flared mouth of arc structure; the arc flared mouth makes the connection parts between the hot top body 1 and the inner sleeve 4 and the graphite ring 5 of the crystallizer as a casting component into arc transitions of corresponding shape and size, to form a liquid storage chamber; the interface angle to the graphite ring 5 is larger than 90 degrees; the sectional opening of the hot top body 1 is circular. The hot top has the advantages of simple mould maintenance, smooth interface surface, improved finished product ratio and metal plasticity, and reduced production cost.
Description
Technical field
The utility model belongs to metallurgy industry Casting Equipment field, is specifically related to a kind of aluminium alloy round cast ingot same level casting that is used for Birmasil circle ingot casting and pushes up with heat.
Background technology
In the prior art, traditional aluminum alloy round ingot casting technique adopts the casting technique equipment of the non-same level of direct-cooling type more, promptly be provided with flow table and cursory funnel on the crystallizer top that is loaded on the mould platform, dummy bar head is equipped with in the bottom, in conjunction with peripheral recirculated cooling water device, form the casting system of aluminum alloy round ingot jointly again.During casting, metal aluminium liquid flows in the crystallizer, through water quench by cursory funnel, dummy bar head moves to the casting downhole with certain speed simultaneously, the alloy aluminum ingot casting 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 alloy aluminum liquid.The weak point of this process equipment is: the level of crystallization control device inner chamber metal bath surface well in the casting process, liquid level is crossed the low ingot casting surface of can causing and is formed cold shut, having Lou when serious, aluminium produces, trace, drawing crack are drawn in the too high ingot casting surface of very easily causing again of liquid level, adopt above-mentioned process equipment in addition, liquid level drop also is difficult to solve during its casting.Though the hot direct casting fabrication technique of same level of the billet of having used at present casting has solved the problems referred to above preferably, but this process equipment is because the heat top becomes 90 ° of right angles with the interface of bottom graphite annulus, so in casting, have the following disadvantages: the one, when repairing a die with the material that repairs a die fast, operating difficulties; The 2nd, because of the difficulty that repairs a die, cause interface surface rough, cause the alloy aluminum bar cast rough; The 3rd, because interface angle is 90 ° of right angles, make when repairing a die interface angle wayward, aluminium liquid dross phenomenon is arranged.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and provide a kind of can reduce or eliminate aluminium liquid dross, segregation little, improve aluminum alloy round ingot casting technique quality, aluminium alloy round cast ingot same level casting that simple to operation, the casting aluminium bar smooth surface of repairing a die, production efficiency are high is with the heat top.
For reaching above-mentioned purpose, technical solution of the present utility model is:
A kind of aluminium alloy round cast ingot same level casting is pushed up with heat, profile is the convex form that the bottom is equipped with round platform, comprise hot top body and pod apertures, its special character is: body centre, described hot top is equipped with a bottleneck shape pod apertures that communicates with crystallizer internal cavity, the lower end of pod apertures has the flare that is shaped as the circular arc structure, this circular arc enlarging makes cover in hot top body and the cast assembly crystallizer, the connector place that the graphite annulus device cooperates is the corresponding arc transition of shape size, and constitute a storage liquid air chamber, with the interface angle of graphite annulus greater than 90 °, the cross section opening shape of described hot top body is circular.
The utility model is that its advantage and good effect are to the improvement on existing circle ingot casting heat top:
Because having adopted, the bottom of body center, hot top pod apertures has the flare that is shaped as up-small and down-big circular arc structure, the interface that makes heat top and graphite annulus is greater than 90 °, the internal chamber wall shape size at connector place is coincide consistent, being convenient to interface repairs a die, and it is simple and convenient to repair a die, and interface surface is smooth.
Adopt the utility model to improve the surface quality of aluminium alloy round cast ingot, make casting aluminium bar smooth surface, reduced aluminium liquid dross phenomenon, the workman is easy to operate during casting, for the workman has saved working time and has alleviated labour intensity, reduce production cost, improved lumber recovery and plastic deformation, helped casting processing.
Description of drawings
Fig. 1 is the structure cutaway view of the utility model aluminium alloy round cast ingot same level casting with the heat top.
Fig. 2 is the casting of the utility model aluminium alloy round cast ingot same level is assemblied in cover in the crystallizer with the heat top a structure cutaway view.
Among Fig. 1-Fig. 2, cover, 5-graphite annulus in the hot top of 1-body, 2-pod apertures, 3-pressure ring, the 4-crystallizer.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
With reference to shown in Figure 1, aluminium alloy round cast ingot same level casting of the present utility model is pushed up with heat, be made up of hot top body 1 and pod apertures 2, hot top body 1 is to do moulding for the light thermal insulation fire-resistant material through the machine compacting anti-No. one in adopting, and profile is the convex form that the bottom is equipped with round platform.Body 1 centre, hot in the present embodiment top is shaped on the pod apertures 2 that a top is bottleneck shape opening, the bottom of pod apertures 2 is shaped on the opening of circular arc structure, be shaped as up-small and down-big tubaeform circular arc enlarging, the cavity shape size of this circular arc enlarging and graphite annulus 5 is corresponding, this enlarging that is designed to the circular arc structure can be more conducive to the shunting of alloy aluminum liquid, reduce aluminium liquid dross, make the crystalline structure of ingot casting tiny evenly, segregation is little, in the such scheme, the lateral opening of hot top body 1 is shaped as circle.
Fig. 2 is that aluminium alloy round cast ingot same level casting of the present utility model is assemblied in the specific embodiment in the cover 4 in the crystallizer with the heat top.Cover 4 is the core work parts with hot top of the present utility model body 1 in this crystallizer, supporting by the internal thread wire connection of pressure ring 3 by cover 4 upper port in its outer round thread and the crystallizer, with hot top body 1 bottom round platform block fastening press-fit be positioned at inner chamber circular arc steps top, crystallizer cover 4 middle part, make body 1 lower end, hot top and be inlaid in graphite 5 corresponding connections not at the place, interior round platform rank of cover 4 lower positions in the crystallizer, pod apertures 2 bottoms and graphite annulus 5 interfaces adopt arc transition, and its interface angle is greater than 90 °.
During casting, the top of hot acrosome body 1 links to each other with shunting disk, and cover 4 is connected use by the step on its peripheral top with the crystallizer overcoat in the crystallizer, realizes the hot direct casting fabrication technique of aluminium alloy round cast ingot same level.
Though in the above-described embodiments the utility model has been done more detailed description and explanation; but those skilled in the art should fully understand under the situation that does not break away from the utility model design that limited by its claim and protection domain, can make multiple improvement in the form and details.
