The principles and spirit of the present utility model are explained in detail below with reference to several representative embodiments thereof.
The utility model provides an embodiment 1 of a multi-station grading casting system for a large slab ingot, which comprises the following steps:
as shown in figures 1 to 2 of the drawings,
The casting chute comprises three casting chutes 2 which are arranged at intervals along the moving direction of the casting mould 1, the distance between the central lines of two adjacent casting moulds 1 along the moving direction of the casting mould 1 is L1, the distance between the central lines of two adjacent casting chutes 2 is L2, wherein L1 is equal to L2, the casting chutes 2 comprise casting spouts 21, the distances between the casting spouts 21 of different casting chutes 2 and the bottom surface of the casting mould 1 are different, and the distance between the casting spouts 21 and the bottom surface of the casting mould 1 along the moving direction of the casting mould 1 is gradually increased.
Through the multistation interval arrangement of the casting chute 2, the grading multiple casting of one casting mould is realized, each station only casts a part of the casting mould 1, and through continuous multiple casting, the integral casting speed is effectively improved, and the productivity is obviously improved.
The casting nozzles 21 of different stations have different heights, namely, the distance between the casting nozzle 21 of the first casting chute 2 and the bottom surface of the casting mould 1 is the lowest along the moving direction of the casting mould 1, so that the scouring force to the casting mould 1 can be effectively reduced during the first casting, the service life of the casting mould 1 is effectively prolonged, and the generation amount of scum is reduced. Wherein, aluminium slag belongs to the oxide skin that salvages from the aluminium liquid the inside, and the less the better is salvaged, more material waste more.
In addition, when casting is performed step by step through the multistation, the casting mould 1 is in a slow moving state all the time, so that the change of casting points is realized, and the service life of the casting mould 1 is prolonged.
When the casting machine is specifically used, three casting chute 2 are arranged at intervals, one third of the casting mould 1 is cast by different casting chute 2, the casting process of one casting mould is finished by continuous casting for three times, the overall casting speed is effectively improved, and the productivity is obviously improved.
In this embodiment, a drainage groove 22 is disposed at one end of the pouring spout 2 away from the pouring spout 21, and a downward concave aluminum liquid groove 23 is disposed between the pouring spout 21 and the drainage groove 22.
In this embodiment, a connecting chute 24 is provided between the pouring spout 21 and the aluminium bath 23.
In this embodiment, the bottom level of the drain chute 22 is lower than the bottom level of the connecting chute 24.
In the concrete casting use process, high-temperature molten aluminum conveyed by a public chute is conveyed into the molten aluminum groove 23, the height of one end of the casting nozzle 21 is smaller than that of the molten aluminum groove 23, and under the action of gravity, the high-temperature molten aluminum enters a casting mould from the casting nozzle 21 to realize casting.
In this embodiment, a rotation adjusting frame 3 that drives the casting chute 2 to rotate and adjusts the height of the casting nozzle 21 is disposed below the casting chute 2.
In this embodiment, the rotation adjustment frame 3 includes a bracket assembly 31 and a driving mechanism disposed on the bracket assembly 31 and driving the pouring chute 2 to rotate;

Specifically, the telescopic rod 32 may be an electric telescopic rod.
In this embodiment, a hinge lug 311 is disposed at the top end of the bracket assembly 31, a connecting lug 25 is disposed on the bottom surface of the pouring chute 2, and the hinge lug 311 is connected with the connecting lug 25 in a penetrating manner through a supporting shaft 312.
Specifically, the coordinated casting chute 2 is rotatably adjusted by the fulcrum 312 through the telescopic action of the electric telescopic rod.
During normal casting, the height of one end of the casting nozzle 21 is smaller than the height of the aluminum liquid groove 23, so that high-temperature aluminum liquid flows into the casting mould to finish casting, and when equipment fails and casting is required to be stopped, the height of the aluminum liquid groove 23 is smaller than the height of one end of the casting nozzle 21, so that high-temperature aluminum liquid casting such as residual aluminum box is realized, and safety is improved.
Specifically, when casting is performed by using casting trays 2 which are arranged at intervals, the arranged casting moulds slowly move to realize casting while moving, in addition, when the casting nozzle 21 corresponds to between two casting moulds in the moving process of the casting moulds, the casting nozzle 21 is lifted upwards through the driving action of an electric telescopic rod, when the casting nozzle 21 corresponds to the casting moulds, the casting nozzle 21 falls down again to perform casting through the driving action of the electric telescopic rod, and the position of a casting point continuously changes in the process, so that the service life of the casting moulds is prolonged.
From the foregoing description of the present specification, it will be further understood by those skilled in the art that terms such as "upper", "lower", "front", "rear", "left", "right", "width", "horizontal", "top", "bottom", "inner", "outer", and the like, which indicate an azimuth or a positional relationship, are based on the azimuth or the positional relationship shown in the drawings of the present specification, are for convenience only in explaining aspects of the present utility model and simplifying the description, and do not explicitly or implicitly refer to devices or elements having to have the specific azimuth, be constructed and operate in the specific azimuth, and thus the azimuth or positional relationship terms described above should not be interpreted or construed as limitations of aspects of the present utility model.
