Description

Technical Field

[0001] The utility model relates to the technical field of aluminum ingot casting, in particular to an anti-overflow structure for an open ladle in aluminum ingot casting. Background Technique

[0002] After high-temperature aluminum liquid is poured into the open ladle and undergoes processes such as static settlement, stirring, slag skimming, and dross removal, the overhead crane lifts the open ladle onto the tilting machine, and the operator manually controls the lifting button of the tilting machine to pour the aluminum liquid into the casting chute and flow into the large flat ingot mold. After the slag skimming and dross removal processes, it is finally cooled by the casting machine to form large flat ingots.

[0003] Sometimes during the production process, due to too much or too full aluminum liquid in the open ladle, when the operator controls the tilting machine to lift too fast or too high during casting, and due to uneven control of the casting speed, the high-temperature aluminum liquid will overflow along the front edge of the open ladle and flow to the bottom of the tilting machine, which may ignite components such as the oil pipes below, easily causing fire accidents and production shutdown accidents, and there are serious safety hazards.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an anti-overflow structure for an open ladle in aluminum ingot casting, including an open ladle body. A baffle is arranged on the upper end surface of the open ladle body facing the casting chute. The inner side surface of the baffle is connected to the open ladle body through an arc transition surface, and the outer side surface of the baffle is welded to the outer side surface of the open ladle body through a connecting block.

[0006] As a preferred technical solution of the utility model, the baffle is of an arc structure, and the length of the baffle is one-third of the circumference of the upper end surface of the open ladle body.

[0007] As a preferred technical solution of the utility model, the height of the baffle is 18 - 20 cm.

[0008] As a preferred technical solution of the utility model, the arc transition surface is made of a high-temperature resistant casting material, which is used to smooth the inner wall of the baffle and the open ladle body to form a seamless connection surface.

[0009] As a preferred technical solution of the utility model, the number of the connecting blocks is three, and the three connecting blocks are evenly distributed along the outer side surface of the baffle.

[0010] As a preferred technical solution of the present utility model, four positioning posts are provided on the upper end surface of the open package body, and four positioning holes adapted to the positions of the positioning posts are provided on the lower surface of the baffle plate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The anti-overflow structure of the aluminum ingot casting open package is reasonably designed and easy to operate. By providing a baffle plate at the upper end of the open package body facing the casting chute, the high-temperature molten aluminum overflowing due to inertia during the lifting and lowering operation of the open package is blocked by the baffle plate, preventing the high-temperature molten aluminum from overflowing, and having reliable stability and good practicability.

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments (for the convenience of description and understanding, the upper part is described as the upper part hereinafter). All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Figure 2 the upper part of

[0019] Please refer to Figures 1-5, the present utility model provides a technical solution: an anti-overflow structure for an open ladle for aluminum ingot casting, including an open ladle body 1. A baffle 2 is arranged on the upper end surface of the open ladle body 1 facing the casting chute. The baffle 2 is made of iron plate and is of an arc structure. The length of the baffle 2 is one-third of the perimeter of the upper end surface of the open ladle body 1, and the height of the baffle 2 is 18 - 20 cm, which can effectively prevent high-temperature aluminum liquid from overflowing. The inner side of the baffle 2 is connected to the open ladle body 1 through an arc transition surface 4. The outer side of the baffle 2 and the outer side of the open ladle body 1 are welded through a connecting block 3 to improve the connection stability between the baffle 2 and the open ladle body 1.

[0020] Furthermore, the arc transition surface 4 is made of a high-temperature resistant casting material, which is used to smooth the inner wall between the baffle 2 and the open ladle body 1 to form a seamless connection surface. Since the inner side of the baffle 2 has to be in direct contact with high-temperature aluminum liquid, using a high-temperature resistant casting material can extend the service life of the baffle 2. At the same time, due to its arc structure, the arc transition surface 4 can effectively slow down the inertial rise of high-temperature aluminum liquid.

[0021] Furthermore, to improve the stability of the baffle 2, the number of connecting blocks 3 is three, and the three connecting blocks 3 are evenly distributed along the outer side of the baffle 2.

[0022] Furthermore, to ensure the accurate installation position of the baffle 2 during installation, four positioning columns 5 are arranged on the upper end surface of the open ladle body 1, and four positioning holes 6 adapted to the positions of the positioning columns 5 are arranged on the lower surface of the baffle 2. Through the cooperation of the positioning columns 5 and the positioning holes 6, rapid positioning during the installation of the baffle 2 is achieved.

[0023] During use: The baffle 2 aligns the positioning holes 6 at its lower end with the positioning columns 5 on the open ladle body 1. After installation, the inner side position of the baffle 2 and the inner wall of the open ladle body 1 are smoothed with a high-temperature resistant casting material to form an arc surface. The outer side of the baffle 2 is welded to the open ladle body 1 through a connecting block to ensure the stability of the baffle 2. When operating the tilting machine, due to too fast or too high lifting, the high-temperature aluminum liquid is blocked by the baffle 2 and cannot overflow.

[0024] The present utility model can effectively prevent the occurrence of other production safety accidents such as fires or personal burns caused by high-temperature aluminum liquid overflowing from the edge of the open ladle during continuous casting of large flat ingots on the tilting machine. Moreover, the transformation and production are time-saving, material-saving, low-cost, easy to operate, have reliable stability and good practicability. It is an effective measure to prevent aluminum overflow and spillage from the open ladle, and can effectively eliminate potential safety hazards.

[0025] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
