Description

Technical Field

[0001] The utility model relates to the field of metal production, and more specifically, to a slag cleaning tool. Background Art

[0002] During the melting and casting production of aluminum and aluminum alloys, after the aluminum liquid is leveled in the melting furnace and reaches the specified slag skimming temperature and after the holding furnace is tilted, it is necessary for workers to use a special slag skimming tool to reciprocally skim the floating slag on the surface of the aluminum liquid in the furnace until the aluminum slag is completely skimmed. Currently, the slag skimming plate of the slag skimming tool is rectangular. When skimming the slag, the aluminum slag easily flows away to both sides. Therefore, it is necessary to reciprocate several times during slag skimming to achieve a better slag skimming effect. However, this will increase the labor intensity of the workers and result in low slag skimming efficiency. Further, with a long slag skimming time, the material of the slag skimming plate will dissolve in the aluminum liquid, leading to a decrease in the cleanliness of the aluminum liquid. Content of the Utility Model

[0003] In order to overcome the problem of poor slag skimming effect caused by the rectangular slag skimming plate in the above technical solution, the utility model provides a slag cleaning tool, which can improve the slag skimming effect.

[0004] To solve the above technical problems, the technical solution adopted by the utility model is: a slag cleaning tool, including a slag cleaning plate and a slag cleaning rod connected to the slag cleaning plate. The slag cleaning plate includes a first arc portion and a second arc portion. The outer peripheral surface at one end of the first arc portion is connected to the outer peripheral surface at one end of the second arc portion. The centers of the arcs of the first arc portion and the second arc portion are both located on the side where the slag cleaning rod is located.

[0005] In the above technical solution, during slag cleaning, the floating slag on the aluminum liquid is skimmed away by the slag cleaning plate. In this process, due to the gathering effect of the first arc portion and the second arc portion, the floating slag will be concentrated at the centers of the first arc portion and the second arc portion respectively. And even if the floating slag flows away from the side of the first arc portion close to the second arc portion, it will only enter the second arc portion and will not go beyond the range of the slag cleaning plate. Similarly, when the floating slag flows away from the side of the second arc portion close to the first arc portion, it will only enter the first arc portion. Finally, the slag cleaning plate can remove more floating slag in one action, thereby reducing the number of reciprocating operations of the workers.

[0006] Preferably, a plurality of notch portions are provided at the bottoms of the first arc portion and the second arc portion. The dross floats on the surface of the molten aluminum. During the process of skimming the dross with the dross skimming plate, the bottom of the dross skimming plate will contact the molten aluminum. When the dross skimming plate moves, the molten aluminum will roll with the movement of the dross skimming plate and adsorb on the dross, resulting in waste of the molten aluminum taken out. The notch portions can reduce the turnover of the molten aluminum during the dross skimming process, reduce the adsorption of the molten aluminum on the dross, and at the same time allow the molten aluminum on the dross to flow away, reducing the molten aluminum taken away by the dross and improving the dross skimming effect. In addition, it can also reduce the resistance of the dross skimming plate during operation.

[0007] Preferably, the notch portion at the center of the first arc portion and / or the second arc portion is larger than the notch portions on both sides. The dross gathered at the centers of the first arc portion and the second arc portion will form a larger volume. The slightly larger size of the notch portion here facilitates the flow of the molten aluminum without allowing the dross to flow away. At the positions of the notch portions on both sides, the volume of the dross is smaller, so the size of the notch portions is smaller to prevent the dross from flowing away.

[0008] Preferably, at least one return hole is provided in the middle sections of the first arc portion and the second arc portion. After the dross accumulates to a certain height, the filtrate adsorbed on the surface of the dross can flow away through the return holes, reducing the molten aluminum taken away by the dross and improving the dross skimming effect. The more the number of return holes, the less molten aluminum is taken away, but the dross skimming plate is more likely to be damaged.

[0009] Preferably, two return holes are provided in the middle sections of the first arc portion and the second arc portion. The two return holes meet the requirement of reducing the amount of molten aluminum taken away, and at the same time enable the dross skimming plate to have a longer service life without being replaced too frequently.

[0010] Preferably, it further includes an adapter plate for connecting the dross skimming plate and the dross skimming rod. The adapter plate fits the outer contour of the side of the dross skimming plate close to the dross skimming rod and is connected to the upper section of the dross skimming plate. The adapter plate is detachably connected to the dross skimming plate and fixedly connected to the dross skimming rod. Since the dross skimming plate directly contacts the molten aluminum and is a vulnerable part, the dross skimming plate and the dross skimming rod are connected through the adapter plate. After the dross skimming plate is damaged, it can be removed from the adapter plate for replacement.

[0011] Preferably, a grip is provided at one end of the dross skimming rod away from the dross skimming plate. The grip facilitates the operation of the dross skimming tool by the staff.

[0012] Preferably, reinforcing portions connected to the adapter plate are respectively provided on both sides of the dross skimming rod. The reinforcing portions can increase the connection strength between the dross skimming rod and the adapter plate, preventing the adapter plate and the dross skimming rod from falling off or breaking due to insufficient connection strength.

[0013] Preferably, the material of the dross cleaning plate is graphite. The dross cleaning plate made of graphite has a high melting point and is not easily contaminated by the molten aluminum. The material of the dross cleaning rod is stainless steel. In order to prevent the dross cleaning rod from being easily broken, stainless steel with a higher hardness can be selected.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: The dross cleaning plate with the first arc portion and the second arc portion can take away more floating dross in a single operation, reduce the operation times of the staff, and improve the efficiency of cleaning the floating dross.

[0020] The technical solutions of the present utility model will be further specifically described below through specific embodiments and in conjunction with the drawings:

[0021] Embodiment 1

[0022] As Figure 1Shown is Embodiment 1 of a slag cleaning tool, including a slag cleaning plate 1 and a slag cleaning rod 2 connected to the slag cleaning plate 1. The slag cleaning plate 1 includes a first arc portion 101 and a second arc portion 102. The outer peripheral surface of one end of the first arc portion 101 is connected to the outer peripheral surface of one end of the second arc portion 102, specifically presenting an "m" shape. The centers of the arcs of the first arc portion 101 and the second arc portion 102 are both located on the side where the slag cleaning rod 2 is located. In this embodiment, the radii of the first arc portion 101 and the second arc portion 102 are the same.

[0023] Working principle of this embodiment: When cleaning the slag, the floating slag on the molten aluminum is scraped away by the slag cleaning plate 1. During this process, due to the gathering effect of the first arc portion 101 and the second arc portion 102, the floating slag will be concentrated at the centers of the first arc portion 101 and the second arc portion 102 respectively. And even if the floating slag flows away from the side of the first arc portion 101 close to the second arc portion 102, it will only enter the second arc portion 102 and will not go beyond the scope of the slag cleaning plate 1. Similarly, when the floating slag flows away from the side of the second arc portion 102 close to the first arc portion 101, it will only enter the first arc portion 101. Eventually, the slag cleaning plate 1 can remove more floating slag in one action, thereby reducing the number of reciprocating operations of the staff.

[0024] Beneficial effects of this embodiment: The slag cleaning plate 1 with the first arc portion 101 and the second arc portion 102 can take away more floating slag in a single operation, reduce the number of operations of the staff, and improve the efficiency of cleaning the floating slag. Specifically, as shown in Table 1 below, the comparison of the slag cleaning effects of different shapes of the slag cleaning plate 1.

[0026]

[0027] Embodiment 2

[0028] As Figure 1-2 Shown is Embodiment 2 of a slag cleaning tool, including a slag cleaning plate 1 and a slag cleaning rod 2 connected to the slag cleaning plate 1. The slag cleaning plate 1 includes a first arc portion 101 and a second arc portion 102. The outer peripheral surface of one end of the first arc portion 101 is connected to the outer peripheral surface of one end of the second arc portion 102, specifically presenting an "m" shape. The centers of the arcs of the first arc portion 101 and the second arc portion 102 are both located on the side where the slag cleaning rod 2 is located. In this embodiment, the radii of the first arc portion 101 and the second arc portion 102 are the same.

[0029] Specifically, a plurality of notch portions 103 are provided at the bottoms of the first arc portion 101 and the second arc portion 102. The notch portion 103 located at the center of the first arc portion 101 and the second arc portion 102 is larger than the notch portions 103 located on both sides. The dross floats on the surface of the molten aluminum. During the dross skimming process of the dross skimming plate 1, the bottom of the dross skimming plate 1 will contact the molten aluminum. When the dross skimming plate 1 moves, the molten aluminum will roll with the movement of the dross skimming plate 1 and adsorb on the dross, resulting in waste of the molten aluminum brought out. The notch portion 103 can reduce the turnover of the molten aluminum during the dross skimming process, reduce the adsorption of the molten aluminum on the dross, and at the same time allow the molten aluminum on the dross to flow away, reducing the molten aluminum carried away by the dross and improving the dross skimming effect. At the same time, based on the fact that the dross gathered at the center of the first arc portion 101 and the second arc portion 102 will form a larger volume, the larger size of the notch portion 103 here can facilitate the flow of the molten aluminum without allowing the dross to flow away. For the position of the notch portions 103 on both sides, the volume of the dross is smaller, so the size of the notch portions 103 is smaller to prevent the dross from flowing away.

[0030] Furthermore, at least one return hole 104 is provided in the middle sections of the first arc portion 101 and the second arc portion 102. After the dross accumulates to a certain height, the filtrate adsorbed on the surface of the dross can flow away through the return hole 104, reducing the molten aluminum carried away by the dross and improving the dross skimming effect. The more the number of the return holes 104, the less the molten aluminum carried away, but the dross skimming plate 1 is more likely to be damaged.

[0031] The working principle of this embodiment: During dross skimming, the dross on the molten aluminum is scraped away by the dross skimming plate 1. During this process, due to the gathering effect of the first arc portion 101 and the second arc portion 102, the dross will be concentrated at the centers of the first arc portion 101 and the second arc portion 102 respectively. And even if the dross flows away from the side of the first arc portion 101 close to the second arc portion 102, it will only enter the second arc portion 102 and will not go out of the range of the dross skimming plate 1. Similarly, when the dross flows away from the side of the second arc portion 102 close to the first arc portion 101, it will only enter the first arc portion 101. Eventually, the dross skimming plate 1 can remove more dross in one action, thereby reducing the number of reciprocating operations of the staff. As the dross gathered in one action increases, the molten aluminum adsorbed on the surface of the dross will also flow away through the notch portion 103 and the return hole 104, and the molten aluminum stirred up by the dross skimming plate 1 and the gathered dross can also flow away through the notch portion 103 and the return hole 104.

[0032] Advantages of this embodiment: The slag cleaning plate 1 with the first arc portion 101 and the second arc portion 102 can remove more floating slag in a single operation, reduce the number of operations of the staff, and improve the efficiency of cleaning the floating slag. The notch portions 103 and the return holes 104 on the first arc portion 101 and the second arc portion 102 can reduce the aluminum liquid carried away by the floating slag and reduce the waste of aluminum liquid.

[0033] Embodiment 3

[0034] As Figure 2-3 Shown in the figure is an embodiment 3 of a slag cleaning tool, including a slag cleaning plate 1 and a slag cleaning rod 2 connected to the slag cleaning plate 1. The slag cleaning plate 1 includes a first arc portion 101 and a second arc portion 102. The outer peripheral surface of one end of the first arc portion 101 is connected to the outer peripheral surface of one end of the second arc portion 102, specifically presenting an "m" shape. The centers of the arcs of the first arc portion 101 and the second arc portion 102 are both located on the side where the slag cleaning rod 2 is located. In this embodiment, the radii of the first arc portion 101 and the second arc portion 102 are the same.

[0035] Among them, a plurality of notch portions 103 are provided at the bottoms of the first arc portion 101 and the second arc portion 102. The floating slag floats on the surface of the aluminum liquid. During the process of the slag cleaning plate 1 skimming the slag, the bottom of the slag cleaning plate 1 will contact the aluminum liquid. When the slag cleaning plate 1 moves, the aluminum liquid will roll with the movement of the slag cleaning plate 1 and adsorb on the floating slag, resulting in waste of the aluminum liquid carried away. The notch portions 103 can reduce the flipping of the aluminum liquid during the slag cleaning process, reduce the adsorption of the aluminum liquid on the floating slag, and at the same time allow the aluminum liquid on the floating slag to flow away, reducing the aluminum liquid carried away by the floating slag and improving the slag cleaning effect.

[0036] Furthermore, at least one return hole 104 is provided in the middle section of the first arc portion 101 and the second arc portion 102. After the floating slag accumulates to a certain height, the filtrate adsorbed on the surface of the floating slag can flow away through the return hole 104, reducing the aluminum liquid carried away by the floating slag and improving the slag cleaning effect. The more the number of the return holes 104, the less the aluminum liquid carried away, but the slag cleaning plate 1 is more likely to be damaged. In this embodiment, two return holes 104 are provided in the middle section of the first arc portion 101 and the second arc portion 102. The middle section mentioned in this embodiment refers to the area between the bottom and the top of the first arc portion 101 and the second arc portion 102 and close to the middle.

[0037] As shown in Table 2 below is the influence of the number of return holes 104 on the amount of aluminum liquid carried away and the service life

[0039]

[0040] Specifically, it further includes an adapter plate 3 for connecting the slag cleaning plate 1 and the slag cleaning rod 2. The adapter plate 3 fits the outer contour of the slag cleaning plate 1 on the side close to the slag cleaning rod 2 and is connected to the upper section of the slag cleaning plate 1. The adapter plate 3 is detachably connected to the slag cleaning plate 1. In this embodiment, the detachable connection is achieved through fasteners. The adapter plate 3 is fixedly connected to the slag cleaning rod 2. In this embodiment, the slag cleaning rod 2 is welded to the adapter plate 3. Since the slag cleaning plate 1 directly contacts the molten aluminum and is a vulnerable part, the slag cleaning plate 1 and the slag cleaning rod 2 are connected through the adapter plate 3. After the slag cleaning plate 1 is damaged, the slag cleaning plate 1 can be removed from the adapter plate 3 for replacement. The upper section of the slag cleaning plate 1 refers to the area from the middle position to the top of the slag cleaning plate. In this embodiment, this area is the area between the return hole 104 and the top of the slag cleaning plate.

[0041] In this embodiment, reinforcing parts 202 connected to the adapter plate 3 are respectively arranged on both sides of the slag cleaning rod 2. The reinforcing parts 202 can increase the connection strength between the slag cleaning rod 2 and the adapter plate 3, and avoid problems such as the detachment or fracture of the connection between the adapter plate 3 and the slag cleaning rod 2 due to insufficient connection strength. To increase the connection effect between the reinforcing parts 202 and the adapter plate 3, the connection positions of the reinforcing parts 202 and the adapter part are respectively located at the middle positions of the first arc part 101 and the second arc part 102.

[0042] The working principle of this embodiment: When cleaning slag, the floating slag on the molten aluminum is scraped away by the slag cleaning plate 1. During this process, due to the gathering effect of the first arc part 101 and the second arc part 102, the floating slag will be respectively concentrated at the centers of the first arc part 101 and the second arc part 102. And even if the floating slag flows away from the side of the first arc part 101 close to the second arc part 102, it will only enter the second arc part 102 and will not go beyond the range of the slag cleaning plate 1. Similarly, when the floating slag flows away from the side of the second arc part 102 close to the first arc part 101, it will only enter the first arc part 101. Eventually, the slag cleaning plate 1 can remove more floating slag in one action, thereby reducing the number of reciprocating operations of the staff. As the amount of floating slag gathered in one action increases, the molten aluminum adsorbed on the surface of the floating slag will also flow away through the notch part 103 and the return hole 104, and the molten aluminum stirred up by the slag cleaning plate 1 and the gathered floating slag can also flow away through the notch part 103 and the return hole 104.

[0043] The beneficial effects of this embodiment: The slag cleaning plate 1 with the first arc part 101 and the second arc part 102 can take away more floating slag in a single operation, reduce the number of operations of the staff, and improve the efficiency of cleaning floating slag. The notch part 103 and the return hole 104 on the first arc part 101 and the second arc part 102 can reduce the molten aluminum taken away by the floating slag and reduce the waste of molten aluminum.
