Description

Technical Field

[0001] The utility model relates to the technical field of casting machines, in particular to a casting slag blocking device. Background Art

[0002] In the secondary aluminum melting and casting workshop, the continuous casting machine is a common device for producing aluminum slab ingots. The casting runner and the continuous casting mold are key components of the continuous casting machine, and they are distributed vertically. During the casting process of aluminum slab ingots, the molten aluminum is continuously poured into the continuous casting mold through the casting runner. The continuous casting mold is a bottomless steel ingot mold with forced water cooling. The molten aluminum continuously condenses and forms in the mold and is continuously pulled out at a certain speed, thus realizing continuous casting.

[0003] During the above casting process, the molten aluminum is continuously poured, so there is always a certain level of molten aluminum in the mold. At the same time, the molten aluminum undergoes oxidation at high temperature to form oxide scale, resulting in the phenomenon of slag inclusion in the molten aluminum, that is, floating slag will form on the surface of the molten aluminum, and the slag is the oxide scale. The oxide scale adheres to the surface of the formed aluminum slab ingot, which will cause the rejection of the ingot surface. Therefore, it is necessary to remove the oxide scale in the molten aluminum, which requires manual slag removal. The slag floating range is wide, and the slag removal operation has low efficiency and high labor intensity. Summary of the Invention

[0004] In order to solve the problem that the floating slag on the surface of the molten aluminum is difficult to clean, the utility model provides a casting slag blocking device. First, the floating slag is filtered through a shunt bag, and then the floating slag is gathered in a smaller range through a slag blocking ring, which is convenient for manual slag removal operation.

[0005] To achieve the above object, the technical solution adopted by the utility model is:

[0006] A casting slag blocking device for filtering and blocking the floating slag on the surface of the molten aluminum, comprising a shunt bag and a slag blocking ring. The shunt bag is in the shape of a net bag, which is convenient for filtering the floating slag and also convenient for the uniform diversion of the molten aluminum. The shunt bag is adjustably connected below the casting runner and is horizontally arranged.

[0007] The slag blocking ring is also adjustably arranged below the casting runner. The slag blocking ring horizontally surrounds the shunt bag on all sides, which is convenient for intercepting the floating slag in the molten aluminum flowing out of the shunt bag. There is a distance between the slag blocking ring and the shunt bag inside and outside, and the intercepted floating slag is located within this distance range. The slag blocking ring extends downward into the continuous casting mold, and the lower part of the slag blocking ring is immersed in the molten aluminum in the continuous casting mold.

[0008] Furthermore, the shunt bag is of a rectangular groove structure, which is convenient for containing the molten aluminum. A support frame is arranged on the shunt bag, and the support frame is convenient for supporting the shunt bag. The support frame is horizontally arranged, and the cross-section of the support frame is in the shape of "Ⅱ". The support frame includes two horizontal support rods and two vertical support rods.

[0009] Furthermore, the two longitudinal struts are arranged between the two transverse struts to ensure the structural strength of the frame, and the transverse struts are arranged perpendicular to the longitudinal struts, and the length of the transverse struts is smaller than that of the longitudinal struts; the two longitudinal struts are arranged side by side on both sides of the diverter bag, and the longitudinal struts are arranged along the length direction of the diverter bag, and the length of the longitudinal struts is greater than the length of the diverter bag.

[0010] Furthermore, four hooks are provided on the casting flow plate, and the four hooks are arranged in a rectangular shape. The hooks are arranged correspondingly at the end of each cross brace, and the hooks are hooked on the cross brace to facilitate hanging the diversion bag; the hooks include a hanging plate and an inner hook adjustably connected to the bottom of the hanging plate, the hanging plate and the inner hook are arranged up and down, and the height position of the inner hook is adjustable.

[0011] Furthermore, the slag stop ring is a rectangular ring body with a certain height, the corners of the slag stop ring are arc transition, the slag stop ring is arranged on the four sides below the diversion bag, and the four corners of the slag stop ring are bolted with mounting plates, and each mounting plate is provided with a mounting chain to facilitate the hanging installation of the slag stop ring;

[0012] The casting flow plate is also provided with four external hooks, which are arranged in a rectangular shape. The external hooks correspond to the mounting chains one by one. The external hooks are hooked on the mounting chains, and the height of the slag retaining ring can be adjusted by hooking the mounting chains at different positions.

[0013] Through the above technical solution, the beneficial effects of the utility model are:

[0014] The utility model has a reasonable structural design. A diverter bag and a slag retaining ring are arranged in sequence below the casting flow plate, and the slag retaining ring is sleeved outside the diverter bag. The aluminum liquid flowing out of the casting flow plate first enters the diverter bag. The slag generated in this process is filtered by the diverter bag. The aluminum liquid flows out through the diverter bag evenly and disperses, and flows into the aluminum liquid in the continuous casting crystallizer from the range of the slag retaining ring. The slag retaining ring is equivalent to the entrance of the aluminum liquid into the crystallizer, and a part of the slag retaining ring is immersed in the aluminum liquid. In this way, the slag generated when the aluminum liquid flows can be confined in the slag retaining ring and will not spread outward over a large area. The slag is effectively controlled, which is convenient for manual cleaning of the slag. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The shunt bag 1 is in the shape of a net bag and has a rectangular groove structure, that is, the shunt bag 1 is a rectangular groove structure made of wire mesh. Furthermore, the shunt bag 1 has a certain volume to hold molten aluminum. The molten aluminum can flow out evenly in all directions through the shunt bag 1, and the floating slag in the molten aluminum is intercepted to prevent it from flowing out.

[0023] When the shunt bag 1 is installed, the shunt bag 1 is horizontally arranged and is adjustably connected below the casting runner plate 3. Here, the adjustable connection means that the height of the shunt bag 1 below the casting runner plate 3 can be adjusted. Specifically, a support frame 5 is provided on the shunt bag 1. The support frame 5 is horizontally arranged to support the shunt bag 1, and the cross - section of the support frame 5 is in the shape of "Ⅱ".

The two longitudinal braces 52 are arranged in parallel on both sides of the shunt bag 1. The distance between the two longitudinal braces 52 is less than the length of the cross - braces 51. The longitudinal braces 52 are arranged along the length direction of the shunt bag 1, the length of the longitudinal braces 52 is greater than the length of the shunt bag 1, and the length of the cross - braces 51 is greater than the width of the shunt bag 1.

[0025] The support frame 5 can support the shunt bag 1. At the same time, four hook - hanging members 6 are provided on the casting runner plate 3, and the four hook - hanging members 6 are arranged in a rectangular pattern. One hook - hanging member 6 is correspondingly arranged at the end of each cross - brace 51. Furthermore, there are four ends of the two cross - braces 51, and the four ends correspond to the four hook - hanging members 6.

[0026] The hook member 6 hooks the cross brace 51, and the entire support frame 5 can be hung by four hook members 6, thereby realizing the hanging installation of the diverter bag 1. The hook member 6 includes a hanging plate 61 and an inner hook 62 adjustably connected to the bottom of the hanging plate 61. The hanging plate 61 is bent into an L shape, and the top of the hanging plate 61 is bolted to the casting flow plate 3. The inner hook 62 is a hook bent into an L shape. The upper end of the inner hook 62 passes through the bottom of the hanging plate 61 and is connected to a nut 7. The upper end surface of the inner hook 62 is arranged with a thread. In this way, the height of the inner hook 62 can be adjusted, thereby adjusting the height of the diverter bag 1.

[0027] A slag stop ring 2 is also adjustable below the casting flow plate 3, and the height position of the slag stop ring 2 can be adjusted up and down. The slag stop ring 2 is a rectangular ring body with a certain height, and the corners of the slag stop ring 2 are arc transitions. The slag stop ring 2 is horizontally arranged around the diversion bag 1. Specifically, the slag stop ring 2 is arranged around the bottom of the diversion bag 1, and there is an overlapping part between the slag stop ring 2 and the diversion bag 1.

[0028] There is a gap between the slag stop ring 2 and the diverter bag 1 inside and outside. The slag stop ring 2 extends downward into the continuous casting crystallizer 4. The bottom of the slag stop ring 2 is immersed in the aluminum liquid in the continuous casting crystallizer 4. The slag stop ring 2 only partially enters the aluminum liquid, and the upper plane of the slag stop ring 2 is higher than the aluminum liquid level.

[0029] When the slag retaining ring 2 is installed, the four corners of the slag retaining ring 2 are bolted with mounting plates 8, and each mounting plate 8 is provided with a mounting chain 9, which is a long strip structure formed by connecting multiple metal rings. Four external hooks 10 are also provided on the casting flow plate 3, and the four external hooks 10 are arranged in a rectangular shape.

The external hooks 10 are hooked on the mounting chains 9, and the external hooks 10 can be hooked on any metal ring on the mounting chains 9, so that the height of the slag retaining ring 2 can be freely adjusted.

[0030] The principle of the utility model is as follows: during the process of aluminum liquid flowing downward from the casting flow plate 3, it first flows into the diverter bag 1. Under the action of the diverter bag 1, the aluminum liquid can flow out evenly from all sides of the diverter bag 1. At the same time, the diverter bag 1 also has a certain filtering effect, which can intercept the scum in the diverter bag 1. The aluminum liquid flowing out of the diverter bag 1 enters the range of the slag retaining ring 2. A part of the lower part of the slag retaining ring 2 is located below the aluminum liquid level in the continuous casting crystallizer 4. Then, the aluminum liquid passes through the slag retaining ring 2 and enters the continuous casting crystallizer 4. Even if there is a small amount of scum in the filtered aluminum liquid, it can be intercepted within the range of the slag retaining ring 2 and will not spread outward over a large area, which facilitates the manual cleaning of the scum.
