Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy production, in particular to a melting and pouring device for aluminum alloy material processing. Background Art

[0002] In the aluminum alloy smelting production process, porosity is an important factor affecting the performance of aluminum alloy.

[0003] During the smelting process, the decomposition of moisture on the surface of the charge at high temperatures, the reaction of water vapor in the air with molten aluminum, and the combustion of hydrocarbon-containing impurities such as oil and lubricants during smelting will all lead to the generation of hydrogen. Since hydrogen has a high solubility in liquid aluminum, but its solubility drops sharply in the solid state, hydrogen precipitates during solidification, forming pores in the alloy.

[0004] The presence of pores reduces the strength and ductility of the material, and pinholes or subcutaneous bubbles appear on the surface of the casting, affecting subsequent processing. At the same time, the pores provide channels for corrosive media, accelerating local corrosion and reducing the corrosion resistance of the alloy. The existing smelting and pouring equipment uses a simple static treatment, relying on the slow floating and escaping of hydrogen to achieve hydrogen removal. The treatment effect is poor, resulting in a high porosity of the finished aluminum alloy. Therefore, improvements are needed. Summary of the invention

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1 In an embodiment of the present invention, a melting and pouring device for processing aluminum alloy materials includes a refining furnace 1, wherein the refining furnace 1 includes a furnace body 101 and a furnace cover 102. To improve the sealing performance of the refining furnace 1, a sealing ring sleeve 104 is fixedly connected to the bottom edge of the furnace cover 102. The length of the sealing ring sleeve 104 is sufficient to completely cover the interface between the furnace cover 102 and the furnace body 101.

[0031] The middle of the furnace cover 102 is fixedly connected with a mounting plate 103, and the middle of the mounting plate 103 is provided with a rotating blowing mechanism 2, see Figure 2The rotary spraying mechanism 2 includes a driving motor 204, the output end of the driving motor 204 is fixedly connected to an air supply pipe 205, the bottom of the air supply pipe 205 is fixedly connected to a rotary spraying nozzle 210, and a guide ring 206 is arranged in the middle of the air supply pipe 205, see Figure 3 The edge of the guide ring 206 is fixedly connected with an air inlet pipe 209, the interior of the guide ring 206 is fixedly connected with a sealing sleeve 207, the sealing sleeve 207 is rotatably connected to the air supply pipe 205, the air supply pipe 205 is provided with a plurality of connecting ports 208 at positions corresponding to the ports of the air inlet pipe 209, and the top of the air inlet pipe 209 is connected with the output end of the external inert gas supply device;

[0032] Inert gas does not react chemically with aluminum liquid, nor does it dissolve in aluminum liquid. It is only necessary to ensure that it is completely discharged to avoid pores. Its core function is to act as a carrier to remove harmful gases (such as hydrogen) and inclusions in aluminum liquid through a physical adsorption mechanism. In this application, a rotary blowing mechanism 2 is set in the refining furnace 1 to spray small bubbles of inert gas into the aluminum liquid. During the rising process of the bubbles, hydrogen and oxide inclusions are adsorbed and discharged, and scum is brought to the liquid surface to form scum, so as to clean up the hydrogen and scum in the aluminum liquid. In this way, the impurity and bubble content in the finished aluminum alloy is reduced, and the quality of the aluminum alloy finished product obtained by casting is improved. In this application, the inert gas is argon or nitrogen. If necessary, the rotary blowing mechanism 2 can also be used to feed a granular refining agent.

[0033] See also Figure 2 An electromagnetic stirrer 108 is fixedly installed at the bottom of the refining furnace 1. The electromagnetic coil of the electromagnetic stirrer 108 generates an alternating magnetic field to drive the aluminum liquid to form a directional flow, thereby forcing the alloy elements to be evenly distributed, eliminating component segregation, and improving the quality of the aluminum alloy product.

[0034] The top of the mounting plate 103 is fixedly connected to a mounting frame 201, an inner wall of the mounting frame 201 is fixedly installed with a lifting hydraulic cylinder 202, an output end of the lifting hydraulic cylinder 202 is fixedly connected to a sliding frame 203, both sides of the sliding frame 203 are slidably connected to the inner wall of the mounting frame 201, and a driving motor 204 is fixedly installed inside the sliding frame 203; by setting mechanisms such as the lifting hydraulic cylinder 202, the height of the rotary blowing nozzle 210 is adjusted, thereby changing the depth of the rotary blowing nozzle 210 below the surface of the aluminum liquid.

[0035] In this embodiment, the rotary blowing nozzle 210 is located in the active area of ​​the upper layer of the aluminum liquid (i.e., a position not exceeding half of the total depth of the aluminum liquid), where the inert gas bubbles can fully diffuse and react with the aluminum liquid; if the rotary blowing nozzle 210 is directly inserted into the bottom of the furnace, the inert gas bubbles need to rise a long distance, which may easily cause the bubbles to merge and become larger, and the adsorption capacity will decrease, while causing the aluminum liquid to roll violently, increasing the risk of splashing; and excessive rolling may cause the floating slag to be re-drawn into the aluminum liquid; the present application achieves adjustment of the position of the rotary blowing nozzle 210 by setting a lifting hydraulic cylinder 202.

[0036] See also Figure 4 In order to achieve uniform dispersion and delivery of inert gas, the rotary blowing nozzle 210 includes a rotary blowing frame 211, and a plurality of rotary blowing balls 213 are fixedly connected to the edge of the rotary blowing frame 211. The outer wall of the rotary blowing ball 213 is provided with a plurality of rotary blowing ports 214, and the rotary blowing ports 214 are connected to the inner cavity side of the rotary blowing frame 211, and the bottom of the air supply pipe 205 is connected to the inner cavity top of the rotary blowing frame 211; the aperture of the rotary blowing port 214 is between 0.5 and 1 mm, and a large number of small bubbles can be generated per unit time through the rotary blowing port 214, thereby increasing the gas-liquid contact area and improving the adsorption efficiency of hydrogen; in order to ensure the high temperature resistance of the rotary blowing nozzle 210, the rotary blowing nozzle 210 is made of 310S stainless steel body and a silicon carbide coating is arranged on the surface.

[0037] See also Figure 3 In order to protect the air supply pipe 205, a protective sleeve 212 is provided on the outer wall of the air supply pipe 205, and the outer wall of the air supply pipe 205 is used to shield and protect it, thereby reducing the impact of the flow of molten aluminum on the position and posture of the air supply pipe 205; the top of the protective sleeve 212 is fixedly connected to the bottom of the sliding frame 203, and the bottom of the protective sleeve 212 is rotatably connected to the rotary blowing nozzle 210; since the air supply pipe 205 itself is a slender tubular structure, if it is directly immersed in the high-temperature molten aluminum and rotated, it is easy to deform, thereby affecting normal operation; the present application has two cooling pipes 215 fixedly connected to the side wall of the protective sleeve 212, one end of the two cooling pipes 215 are connected to an external water pump, and the two cooling pipes 215 are used for water inlet and water outlet, respectively, so that the water flow can continuously flow in the gap between the protective sleeve 212 and the air supply pipe 205, thereby achieving cooling of the air supply pipe 205.

[0038] See also Figure 2 and Figure 5 A plurality of exhaust suction cups 114 are fixedly mounted on the bottom edge of the mounting plate 103, and a suction pipe 113 is fixedly connected to the top of each of the exhaust suction cups 114. One end of the suction pipe 113 is connected to the air inlet end of an external vacuum pump. Through the arrangement of the suction pipe 113 and the exhaust suction cup 114, the hydrogen and other gases overflowing during the refining process are extracted and discharged, so as to avoid secondary combination and contamination with the aluminum liquid.

[0039] See also Figure 7 A smelting furnace 4 is arranged on one side of the refining furnace 1. In the present application, the preliminary smelting of the raw materials and the slagging process are concentrated in the front smelting furnace 4, that is, the melting and refining are operated in stages to avoid cross contamination and ensure that the impurity content of the refining furnace 1 is lower during the refining stage; a filtering and degassing mechanism 3 is arranged on the other side of the refining furnace 1; the refining furnace 1 and the smelting furnace 4 are connected through a converter tube 109, a converter pump 111 is fixedly installed in the middle of the converter tube 109, the refining furnace 1 is connected to the filtering and degassing mechanism 3 through a drainage pipe 110, a drainage pump 112 is fixedly installed in the middle of the drainage pipe 110, a supporting ring 106 is fixedly connected to the bottom of the inner wall of the refining furnace 1, and a supporting ring 106 is fixedly connected to the bottom of the inner wall of the refining furnace 1. A filter frame 105 is placed on the top of the support ring 106, the port position where the converter tube 109 is connected to the refining furnace 1 is located above the filter frame 105, and the port position where the drainage pipe 110 is connected to the refining furnace 1 is located below the filter frame 105. By utilizing the existence of the filter frame 105, secondary filtration and separation of impurities are achieved during the transportation process, and the slag removal operation in the front smelting furnace 4 is coordinated to achieve waste slag removal, so that the furnace opening and slag removal operation does not need to be performed during the refining stage, avoiding the contact between the outside air and the aluminum liquid during the refining stage, and effectively reducing the oxidation and pollution of the aluminum liquid; the above-mentioned converter pump 111 drainage pump 112, etc. are all high-temperature molten metal pumps, which are implemented using existing technical means.

[0040] See also Figure 2 and Figure 6 To facilitate the removal and cleaning of the filter frame 105, the filter frame 105 includes a connecting ring 1051, and a plurality of connecting holes 1052 are opened on the edge of the connecting ring 1051. A plurality of connecting columns 107 are fixedly connected to the top of the supporting ring 106, and the plurality of connecting columns 107 are respectively slidably connected to the plurality of connecting holes 1052.

At the same time, the vertical sliding docking method and the setting of the hanging ring 1055 also make it more convenient to lift and remove the filter frame 105 as a whole through the hanging ring 1055.

[0041] See also Figure 7 and Figure 8The filtering and degassing mechanism 3 includes a degassing tower 301, and a filter 306 is fixedly installed in the middle of the inner wall of the degassing tower 301. The filter 306 divides the inner cavity of the degassing tower 301 into a processing cavity and a static cavity. In this embodiment, the filter 306 is a foam ceramic plate. The existence of the filter 306 blocks and removes bubbles and some residual impurities in the aluminum liquid, thereby improving the purity of the aluminum liquid. Prior to this, in order to further improve the removal efficiency of hydrogen in the aluminum liquid, an air supply ring 307 is fixedly installed in the middle of the inner wall of the processing chamber, and a plurality of air supply holes 308 are opened on the inner wall of the air supply ring 307. An air supply pipe 309 is fixedly connected to one side of the air supply ring 307, and one end of the air supply pipe 309 is used to connect an external inert gas.

A plurality of shear plates 305 are fixedly connected to the bottom of the stirring rod 304, and the height of the shear plates 305 is consistent with the height of the air supply ring 307; the aluminum liquid is sheared into fine droplets to increase the contact area between the inert gas and the aluminum liquid and the dehydrogenation efficiency; after entering the static chamber, the aluminum liquid is allowed to stand for a period of time to ensure that the bubbles fully float up, and at the same time, cooperate with the degassing pipe 310 fixedly connected to the top of one side of the static chamber to extract and discharge the floating and scattered airflow, and generate negative pressure to improve the overflow efficiency of the airflow; in order to discharge the aluminum liquid after the static is completed, a discharge pipe 311 is fixedly installed at the bottom of one side of the static chamber, and a discharge pump 312 is fixedly installed in the middle of the discharge pipe 311.

[0042] When the present invention is used, raw materials are put into the smelting furnace 4, and the smelting furnace 4 is started to heat and melt the raw materials. During this period, the furnace cover 102 is opened to add ingredients and remove slag.

Then the inert gas bubbles rise in the aluminum liquid, and are mixed with the adsorbed hydrogen and oxides in the rising process, and are entrained and discharged, and brought to the liquid surface to form scum, so as to clean the hydrogen and scum in the aluminum liquid; at the same time, the vacuum pump is started to discharge the escaped hydrogen and other waste gases through the exhaust suction cup 114 and the vacuum pipe 113;

[0044] After refining is completed, the drainage pump 112 is started to send the aluminum liquid in the refining furnace 1 into the degassing tower 301.
