AI Technical Summary
In the aluminum molten metal production process, the utilization rate of magnesium ingots is low because magnesium ingots are prone to floating during the smelting process, which leads to volatilization upon contact with air. Existing slag removal tools are difficult to fix effectively, affecting production costs and efficiency.
An aluminum alloy molten aluminum processing structure is adopted, including a slag removal arm, a settling structure, and a flow-blocking structure. Through the cooperation of the settling seat and the flow-blocking structure, the magnesium ingot is ensured to be located in the containment seat during the smelting process. The flow-blocking structure adjusts the size of the liquid inlet to prevent the magnesium ingot from floating. Combined with an electromagnetic stirrer, the utilization rate of the magnesium ingot is improved.
The utilization rate of magnesium ingots was increased to 99.5%, and the smelting process was carried out continuously, which improved the overall processing efficiency and reduced production costs.

Description
TECHNICAL FIELD
[0001] The present application relates to an aluminum alloy molten aluminum processing structure, in particular to an aluminum alloy molten aluminum processing structure and a processing method thereof. BACKGROUND
[0002] Aluminum ingot alloy is formed by molten aluminum, and the molten aluminum is prepared by using pure aluminum or recycled aluminum as raw material, adding other elements such as silicon (Si), copper (Cu), magnesium (Mg), iron (Fe) and the like according to international standards or special requirements to improve the deficiency of pure aluminum in castability, chemistry and physicality. It is widely used in industry and its usage is only second to steel.
[0003] In the preparation process of molten aluminum, first, a proper amount of metallic silicon is added to the recycled liquid with aluminum components, and then manganese additive is added after the metallic silicon is melted. Finally, magnesium ingot is extruded to complete the first refining. According to different requirements of aluminum ingot alloy, other substances can also be added in the above process. However, during the addition of magnesium ingot, the magnesium ingot is often floating on the top of the molten aluminum due to its light density. When it is melted, the side in contact with the air will volatilize and lose, resulting in a decrease in the utilization rate of magnesium ingot and an increase in the overall production cost.
[0004] In the prior art, the magnesium ingot is pressed down by a slag removal tool so that it does not contact with the air, but there are still many problems. First, the temperature of the smelting furnace is high, and it is difficult for workers to approach, so it is difficult to ensure whether the magnesium ingot is truly not in contact with the air. Second, during the process of pressing down the magnesium ingot by the slag removal tool driven by a forklift structure, the magnesium ingot will float to the surface of the molten aluminum from another direction when it melts a part, which cannot completely solve the problem of magnesium ingot floating.
[0005] Therefore, the present application aims to provide an aluminum alloy molten aluminum processing structure and a processing method thereof, which can stably position the magnesium ingot at the bottom of the smelting furnace and does not affect the slag removal action during smelting. SUMMARY

Therefore, the features with "first", "second" can be explicitly or implicitly included one or more features. In the description of the present application, the meaning of "multiple" is two or more than two, unless otherwise specifically limited.
[0039] The existing fixed magnesium ingot is often only pressed down by the rake slag tool, however, with the progress of the reaction, the magnesium ingot will be decomposed into magnesium blocks of different sizes, the magnesium blocks will float to the surface of the aluminum liquid and contact with the air, thereby reducing the utilization rate of the magnesium ingot, the fixing ability and fixing precision of the rake slag tool are limited, and the requirement for the forklift worker is high, therefore, in order to solve the above technical problems, the present application proposes the following technical scheme:
[0040] Referring to Figures 1-7 As shown in the figure, an aluminum alloy molten aluminum processing structure, comprising: a rake arm 10, the rake arm 10 has an extension rod 11 locked on the forklift arm, the extension rod 11 is connected with a rake seat 12; a settling structure 20 is sleeved and fixed on the extension rod 11, the settling structure 20 includes a fixed seat 21 which is clamped on the top of the extension rod 11, a settling seat 22 which is sleeved outside the fixed seat 21 and is in sliding connection with the fixed seat 21, a containing seat 23 which is engaged in the settling seat 22 for placing metal blocks, the outer wall of the containing seat 23 is annularly provided with a plurality of liquid inlet ports 231, with the preliminary descent of the forklift arm, the containing seat 23 is immersed in the molten aluminum liquid, the metal blocks in the containing seat 23 are melted by the aluminum liquid, with the secondary descent of the forklift arm, the settling seat 22 slides upward, the rake seat 12 contacts with the bottom wall of the smelting furnace to perform slag removal; an outer drive structure 30 is sleeved on the outer wall of the settling seat 22, the outer drive structure 30 is connected with a flow resistance structure 40 through a plurality of connecting arms, the flow resistance structure 40 is tightly attached to the outer side of the containing seat 23, the outer drive structure 30 drives the flow resistance structure 40 to adjust the opening degree of the liquid inlet ports 231 on the containing seat 23 after rotating.
[0041] In the embodiment, the slagging arm 10 is a conventional slagging structure, also known as a raking structure, which is mainly used for raking the slag of the smelting furnace after combustion, and can also be used for raking part of the sample for testing. The slagging arm 10 mainly comprises an extension rod 11 and a slagging seat 12. The extension rod 11 is mainly used to ensure the distance between the forklift and the smelting furnace, so as to avoid the influence of the temperature of the smelting furnace on the forklift and the driver. The slagging seat 12 is made of high-temperature-resistant metal, and the inner side of the slagging seat 12 is welded with multiple reinforcing ribs to ensure the use strength.
[0042] The settling structure 20 in the embodiment is divided into three parts. The first part is a fixing seat 21 for fixing, the second part is a settling seat 22 for moving, and the last part is a containing seat 23 for placing. In the fixing seat 21, the welding method is adopted, that is, the top of the fixing seat 21 is directly sleeved on the outer wall of the extension rod 11 in an integral structure with a circular ring. After the installation position of the fixing seat 21 is determined, welding is performed. The settling seat 22 cooperates with the fixing seat 21. Under the condition that no external force is applied, the settling seat 22 does not have any relative displacement with the fixing seat 21 under the action of its own gravity. When the fork arm moves downward, the containing seat 23 touches the bottom, and then acts on the entire settling seat 22 to make it move upward and relatively move with the fixing seat 21. The containing seat 23 is used for placing the cut magnesium ingot. The weight of the magnesium ingot needs to be calculated before being placed in the containing seat 23, so as to ensure that the smelted aluminum liquid meets the requirements. After the position of the containing seat 23 is lowered, the aluminum liquid is poured into the molten magnesium ingot from the liquid inlet 231 of the containing seat 23.
[0043] It should be noted that the distance between the entire settling structure 20 and the slagging seat 12 should not be too close. On the one hand, due to the counterweight, if all the weight is applied to one end of the extension rod 11, the fixed end of the extension rod 11 is easy to bend or even break. On the other hand, it is also to avoid the influence of the high-temperature aluminum liquid at the bottom of the smelting furnace on the welding seam between the fixing seat 21 and the extension rod 11.
[0044] In order to adapt to the gradual reduction of the volume of the magnesium ingot during the entire reaction process, a flow resistance structure 40 is arranged outside the liquid inlet 231 in the containing seat 23. With the progress of the reaction, the flow resistance structure 40 gradually changes its position to continuously adjust the size of the liquid inlet 231, so that the magnesium ingot with reduced volume does not have the condition to slide out of the liquid inlet 231.
[0045] The outer driving structure 30 is used to rotate the flow resistance structure 40 to change the position of the flow resistance structure 40. The outer driving structure 30 can be started in many ways, for example, the mass of the magnesium ingot in the containing seat 23 can be detected to know the entire reaction process through the change of the weight, or the containing seat 23 can be automatically controlled to rotate according to a certain frequency according to the pre-play time. It should be noted that the high temperature of 600-800 ℃ should be considered in the process of selecting the scheme.
[0046] The use principle of the present application is as follows:
[0047] First, the slag arm 10 is locked to the fork arm of the forklift, ensuring that the slag arm 10 can change height with the lifting of the fork arm and change the front and rear position with the forward and backward movement of the forklift, then the forklift worker adjusts the angle of the forklift into the smelting furnace, pushes the slag arm 10 into the smelting furnace, then the fork arm is lowered for the first time until the containing seat 23 is completely immersed in the aluminum liquid, the aluminum liquid enters the containing seat 23 through the liquid inlet 231 to melt the magnesium ingot, and the relative position of the flow resistance structure 40 and the containing seat 23 is continuously adjusted during the melting process, so that the utilization rate of the magnesium ingot is increased to more than 99.5%, and after the smelting is completed, the position of the fork arm is lowered for the second time, the settling seat 22 is raised along the fixed seat 21, the scraping seat 12 touches the bottom, and the first or second raking is started.
[0048] If the magnesium ingot used for addition is a magnesium ingot with a large volume, the melting speed is slow, which can affect the overall preparation efficiency, so the magnesium ingot in the embodiment is cut into a fan-shaped structure, and the containing seat 23 corresponds to the warehouse body 232 for containing metal blocks, the warehouse body 232 is divided into several melting cavities 233, each melting cavity 233 corresponds to a liquid inlet 231, the aluminum liquid melts the metal blocks in the melting cavity 233 through the liquid inlet 231, and the originally large magnesium ingot is divided into small magnesium blocks through the separately arranged warehouse body 232, so as to increase the contact area with the solution, thereby quickly dissolving in the aluminum liquid.
[0049] In the embodiment, the smelting furnace adopts an electromagnetic stirrer to drive the aluminum liquid to rotate clockwise, and in order to facilitate the aluminum liquid in rotation to flow into the containing seat 23, the liquid inlet 231 is inclined, and the inclination direction of the liquid inlet 231 corresponds to the flow direction of the aluminum liquid, so that the aluminum liquid in flow can quickly flow into the containing seat 23 and then quickly flow out, and compared with simple immersion and penetration, the heat transfer rate is faster.
[0050] If the melting cavity 233 is a complete clamping cavity, except for the outermost side of the magnesium ingot, the aluminum liquid is difficult to contact the magnesium ingot in the initial stage of contact with the aluminum liquid, so the melting speed of the magnesium ingot is difficult to guarantee, and for this, the melting cavity 233 is a fan-shaped cavity, the melting cavity 233 has a mold cavity 234, the mold cavity 234 is arranged between the melting cavity 233, the mold cavity 234 is uniformly provided with contact grooves 2341 at equal intervals, the magnesium ingot is placed in the mold cavity 234, and when the aluminum liquid flows into the melting cavity 233, it flows into the gap between the mold cavity 234 and the melting cavity 233 and fully contacts the magnesium ingot through the contact grooves 2341, so that each surface of the magnesium ingot can contact the aluminum liquid, thereby enabling the magnesium ingot to quickly melt.
[0051] In the adjusting process of the flow blocking structure 40, it is a step-by-step adjusting process, which will gradually seal the liquid inlet 231 with the reaction, and specifically: the flow blocking structure 40 includes a ring plate 41 closely attached to the outer wall of the containing seat 23, and a plurality of flow blocking pieces 411 are arranged on the ring plate 41, the flow blocking pieces 411 are staggered with the liquid inlet 231 when the containing seat 23 is not immersed in the aluminum liquid, and the ring plate 41 further includes a plurality of plug-in blocks 412, which are connected with the connecting arm, in the initial stage of the embodiment, the flow blocking pieces 411 on the ring plate 41 are staggered with the liquid inlet 231, at this time the aluminum liquid entering amount is the largest, and the magnesium ingot can be quickly dissolved, and with the dissolution of the magnesium ingot, the flow blocking pieces 411 begin to partially coincide with the liquid inlet 231, the magnesium ingot with a smaller volume after being dissolved cannot fall out of the reduced liquid inlet 231, until the magnesium ingot is completely used up, in the embodiment, the ring plate 41 cannot rotate independently, but can only be driven by the external driving structure 30, so the ring plate 41 needs to be provided with a plurality of plug-in blocks 412 connected with the connecting arm, since the connecting arm is connected with the external driving structure 30, when the external driving structure 30 rotates, the ring plate 41 also rotates.
[0052] Actually, in another embodiment of the case, the external driving structure 30 can not be provided, and the flow blocking structure 40 is directly movably sleeved on the outer wall of the containing seat 23, which will naturally drive the ring plate 41 to rotate with the rotation of the aluminum liquid, and the ring plate 41 will continuously rotate to intermittently close the liquid inlet 231, which can also block the magnesium ingot that may fall out, but the blocking effect is not as good as the above-mentioned effect.
[0053] In the case of applying the external driving structure 30, in the embodiment, the external driving structure 30 is a gear nested on the settling seat 22, the bottom end of the gear is fixedly connected with the connecting arm, the external driving structure 30 is engaged with a driving member 50, the driving member 50 has a rack 51 engaged with the gear, the power end of the rack 51 is engaged with a motor 52 with a pinion, the motor 52 is fixed on a sliding seat 53, the sliding seat 53 realizes up and down sliding through a track 54 welded on the fork arm of the forklift, and specifically: the motor 52 drives the rack 51 to rotate, and then the rack 51 drives the external driving structure 30 to rotate, so that the external driving structure 30 drives the flow blocking structure 40 to do circular motion, but the motor 52 is connected with the external driving structure 30 through the rack 51, and the external driving structure 30 will change position with the settling seat 22, so the motor 52 cannot be fixed, but needs to realize up and down sliding through the cooperation of the sliding seat 53 and the track 54;
[0054] In the embodiment, the linear motor needs to be arranged on the sliding seat 53, and the sliding seat 53 and the motor 52 are driven to move upward in the process of the secondary lowering of the forklift arm, so as to match the upward movement of the settling seat 22, so that the cooperation of the motor 52, the rack 51 and the outer driving structure 30 will not appear fault, and in order to ensure the stability of the whole, the rack 51 can be arranged in two sections, which are respectively located on the two sides of the outer driving structure 30, and in other embodiments, chain, chain plate and other structures can be used instead.
[0055] Since the slagging arm 10 and the settling structure 20 need to enter the high-temperature smelting furnace, most electromagnetic mechanisms and hydraulic mechanisms are not suitable for being used as the power structure of the settling seat 22, so in the embodiment, the settling seat 22 and the fixed seat 21 adopt the free cooperation mode, that is, they fall by gravity and are retracted by external force, and specifically, the settling seat 22 includes a cavity 221 with a spiral top, and a mounting disc 222 welded at the bottom of the cavity 221, and the fixed seat 21 has a limiting plate 211 at the bottom, and the cavity 221 is limited and fixed by the limiting plate 211 when sliding up and down along the fixed seat 21. Due to the limiting plate 211, the fixed seat 21 will not fall out of the cavity 221, and because the area of the limiting plate 211 is the same as the axial area of the cavity 221, the relative movement between the settling seat 22 and the fixed seat 21 is guided to a certain extent, so that the settling seat 22 can fall to the lowest end when not subjected to external force, and after touching the bottom, the limiting plate 211 will move downward in the cavity 221, and the spiral cavity 221 can ensure the sealing of the two, avoid the limiting plate 211 from falling out, and also avoid the aluminum liquid from splashing into it to cause influence.
[0056] When the magnesium ingot is installed, the magnesium ingot is first installed in the containing seat 23, and then the containing seat 23 is matched with the settling seat 22, and specifically, the bottom of the mounting disc 222 is provided with a threaded groove 2221, and the top of the containing seat 23 is further fixed with a threaded column 235, the threaded column 235 is matched with the threaded groove 2221 to make the containing seat 23 closely fit with the settling seat 22, after the installation of the magnesium ingot is completed, the containing seat 23 can be directly screwed into the threaded groove 2221 of the mounting disc 222 through the threaded column 235, the cooperation between the threads is not affected by high temperature, and it needs to be mentioned that the bottom plate of the containing seat 23 is locked by bolts, so that the magnesium ingot will not fall out after installation.
[0057] In another embodiment of the present application, an aluminum alloy liquid processing method is also provided, which specifically includes:
[0058] Step one: lock the slagging arm 10 to the specified forklift arm, and install the settling structure 20, the outer driving structure 30, the flow resistance structure 40 and the driving part 50, lower the forklift arm, and immerse the settling structure 20 and the flow resistance structure 40 into the prepared aluminum liquid.
[0059] Step two: start electromagnetic stirrer in smelting furnace, make aluminum liquid along the order of liquid inlet 231 into the settlement structure 20 to dissolve metal block, mixed fluid is returned to smelting furnace again;
[0060] Step three: with the progress of the dissolution process, the flow resistance structure 40 is constantly moved to the direction of liquid inlet 231 until completely closing the liquid inlet 231;
[0061] Step four: continue to lower the forklift arm, so that the rake seat 12 touches the bottom, move the forklift to rake slag
[0062] Using the above method, the two steps can be carried out continuously, so as to improve the efficiency of aluminum liquid processing.
[0063] Further comprising: the step two further comprises: the aluminum liquid filled in the settlement structure 20 will fill in the gap between the mold cavity 234 and the molten cavity 233 to quickly dissolve the metal block.
[0064] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
