Description

Technical Field

[0001] The present invention relates to the technical field of aluminum master alloy cooling casting, and specifically relates to a continuous chill casting equipment for aluminum master alloy. Background Art

[0002] Aluminum alloy fittings have been widely used in various fields such as automobiles, engines, aerospace, and new energy; with the maturity of technology and the improvement of product performance, the service life of main engines in each field has been significantly extended, which puts higher requirements on the material properties of aluminum alloy components. Adding intermetallic aluminum master alloy to the melting of aluminum alloy can improve the processability and material properties of aluminum alloy. The intermetallic aluminum master alloy promotes nucleation in the liquid state and plays a role in refining the solidification structure. For aluminum master alloy containing intermetallic compounds, the chill condition will make the intermetallic compounds more finely and dispersedly distributed, which will make the nucleation promotion effect of the intermetallic compounds better, the material processability and material use performance better, and at the same time, the production efficiency requirement is high. This requires appropriate equipment to produce aluminum master alloy.

[0003] Existing wheel-belt type aluminum alloy cooling casting and forming equipment generally has a crystallizing wheel, with a steel belt coiled around the outside of the crystallizing wheel, and an aluminum alloy forming groove is formed between the steel belt and the crystallizing wheel. The direct water cooling method is used to cool and form the aluminum liquid. For example, CN215544774U discloses a crystallizing wheel water cooling system for continuous aluminum casting, which is provided with an inner cold water collecting pipe, an outer cold water collecting pipe, and a side cold water collecting pipe; CN202120182U discloses an efficient aluminum continuous casting machine, and the lower part of this aluminum continuous casting machine is immersed in water for cooling and forming. When these aluminum casting cooling and forming equipment water-cool the outer steel belt, they use the methods of directly spraying water or immersing in water. Such cooling does not conform to the chill of aluminum master alloy, and the aluminum master alloy product after cooling and forming will carry water when removed from the crystallizing wheel. After the water evaporates, water marks will be left, affecting the quality of the product. In addition, the water in the micropores of the workpiece will remain in the workpiece. The aluminum master alloy material is added to the molten metal liquid, and the presence of a small amount of water will also instantaneously evaporate and cause an explosion. Therefore, aluminum master alloy is strictly prohibited from containing water. Summary of the Invention

[0004] In order to solve the problem of unreasonable direct water cooling method in the aluminum master alloy cooling casting equipment, the present invention provides a continuous chill casting equipment for aluminum master alloy in which cooling water does not directly contact the aluminum master alloy.

[0005] To solve the above technical problems, the present invention includes a chassis and a cooling and forming wheel for cooling molten aluminum master alloy. At least one groove distributed along the circumferential direction is formed on the wheel surface of the cooling and forming wheel. A flexible steel belt for extruding the cooling and forming wheel is arranged outside the cooling and forming wheel. A semi-circular space is formed between the flexible steel belt and the groove of the cooling and forming wheel. Its structural feature is that: the device further includes a cooling wheel for cooling the flexible steel belt. The cooling wheel and the cooling and forming wheel are located on both sides of the flexible steel belt. The section of the flexible steel belt wound outside the cooling wheel and the cooling and forming wheel is in an "S" shape; the device further includes an air knife for assisting in cooling the molten aluminum master alloy. The air outlet formed by the blade of the air knife faces the flexible steel belt wound outside the cooling and forming wheel.

[0006] After adopting the above structure, the molten aluminum master alloy enters the semi-circular space formed between the flexible steel belt and the groove of the cooling and forming wheel. The cooling and forming wheel directly contacts the molten aluminum master alloy to produce a cooling effect. The cooling wheel contacts the flexible steel belt to directly cool the flexible steel belt. The flexible steel belt then contacts the molten aluminum master alloy to produce a cooling effect. The cooling wheel plays an indirect pre-cooling role. The air blown out by the air knife blows towards the flexible steel belt wound outside the cooling and forming wheel, and the air takes away the heat outside the flexible steel belt, which has an auxiliary cooling effect on the molten aluminum master alloy. The molten aluminum master alloy in the semi-circular space is rapidly cooled and formed under the combined action of the cooling and forming wheel, the cooling wheel and the air knife. During the entire cooling and forming process, the molten aluminum master alloy does not contact water, and the product does not carry water marks and moisture.

[0015] Furthermore, a locking support wheel is provided below the base frame.

Below the cooling and forming wheel 2 and the cooling wheel 3 and near the cooling and forming wheel 2, there is an air knife 5. The left and right sides of the air knife 5 are respectively fixed to the inner sides of the first side plate 18 and the second side plate 19. An air pipe joint 20 for connecting the air knife 5 to the air source is arranged on the first side plate 18. The air outlet formed by the blade edge of the air knife 5 faces the flexible steel belt 4 coiled outside the cooling and forming wheel 2. The feeding hopper 16 for the aluminum master alloy liquid is installed above the cooling and forming wheel 2 and the cooling wheel 3. The feeding hopper 16 is provided with two flat discharge ports 1601 corresponding to the positions of the trapezoidal grooves 202. The discharge ports 1601 are located above the semi-circular space 203. The aluminum master alloy liquid poured into the feeding hopper 16 enters the inside of the semi-circular space 203 from above through the discharge ports 1601, and after cooling and forming, an aluminum master alloy arc-shaped strip material is formed in the trapezoidal groove 202. Between the first side plate 18 and the second side plate 19, there is a stripping plate 14 for stripping the formed aluminum master alloy strip material 22 from the trapezoidal groove 202. One end of the stripping plate 14 extends into the trapezoidal groove 202. The end of the stripping plate 14 extending into the trapezoidal groove 202 is provided with an arc adapted to the radian of the trapezoidal groove 202. The bottom surface of the stripping plate 14 and the arc form a sharp blade edge 1401 that fits on the surface of the trapezoidal groove 202. Between the first side plate 18 and the second side plate 19 and below the stripping plate 14, there is a U-shaped guide plate 15 for guiding and sending out the stripped aluminum master alloy strip material 22. The aluminum master alloy strip material 22 is cut into a certain length when passing through the automatic fixed-length pneumatic cutting device 21 to obtain the required aluminum master alloy product.

[0024] It should be noted that: ordinary seals can be selected for the cooling forming wheel seal ring 206 and the cooling wheel seal ring 304; the automatic fixed-length pneumatic cutting device 21 belongs to the extended part and will not be elaborated here.

[0025] Working principle: Under the elastic force of the compression spring 1301 and the tension spring 1302, the flexible steel belt 4 is tensioned and wound around the outside of the cooling forming wheel 2, the cooling wheel 3, the steel belt tensioning wheel 9, and the steel belt fixed rotating wheel 8. The semi-circular space 203 formed between the flexible steel belt 4 and the cooling forming wheel 2 is the space for the cooling and forming of the aluminum master alloy liquid. The cooling forming wheel 2, the cooling wheel 3, and the air knife 5 provide a cooling source for the cooling of the aluminum master alloy liquid. The universal seal joint 17 near the second side plate 19 is connected to the cooling water inlet pipe, and the universal seal joint 17 near the first side plate 18 is connected to the cooling water drain pipe, and vice versa; the air pipe joint 20 is connected to the air source pipe. Before casting the aluminum master alloy liquid, cooling water is passed into the cooling forming wheel 2 and the cooling wheel 3, and compressed air is passed into the air knife 5. The variable frequency speed regulating motor 10 is started, and the driving gear 11 drives the transmission gear 6 and the driven gear 7 to rotate. The cooling forming wheel 2, the cooling wheel 3, the steel belt tensioning wheel 9, the steel belt fixed rotating wheel 8, and the flexible steel belt 4 rotate accordingly. The molten aluminum master alloy liquid is poured into the feed hopper 16, flows out from the discharge port 1601 to the trapezoidal groove 202, and then enters the semi-circular space 203. The cooling forming wheel 2 directly contacts and cools the aluminum master alloy liquid. The flexible steel belt 4 is wound around the outside of the cooling wheel 3. After the cooling wheel 3 cools the flexible steel belt 4, the flexible steel belt 4 contacts the aluminum master alloy liquid again, and the cooling wheel 3 plays an indirect pre-cooling role. The compressed air blown out by the air knife 5 blows onto the surface of the flexible steel belt 4, and the air takes away the heat on the flexible steel belt 4, playing an auxiliary cooling role. Under the cooling action of the cooling forming wheel 2, the cooling wheel 3, and the air knife 5, the aluminum master alloy liquid cools and forms in the semi-circular space 203. The obtained aluminum master alloy strip 22 rotates with the cooling forming wheel 2. When the starting end hits the edge 1401 of the unloading plate 14, it is peeled off and changes the movement direction, and is discharged along the U-shaped guide plate 15. When passing through the automatic fixed-length pneumatic cutting device 21, it is cut into sections of a certain length. Parameters such as the feeding rate of the aluminum master alloy liquid, the flow rate of the cooling water, and the rotation speed of the variable frequency speed regulating motor 10 are adjusted by those skilled in the art according to common sense and actual situations. The cooling medium water flows in the closed space inside the cooling forming wheel 2 and the cooling wheel 3 and does not contact other components. During the whole process, the aluminum master alloy liquid does not contact water, and the obtained aluminum master alloy product does not carry water marks and moisture; the aluminum master alloy liquid is rapidly cooled under the triple cooling conditions of the cooling forming wheel 2, the cooling wheel 3, and the air knife 5. By changing the flow rates of the cooling water and the compressed air to adjust the rapid cooling conditions, it is easy to find appropriate rapid cooling conditions, which is beneficial to the promotion of nucleation effect of the intermetallic compound aluminum master alloy; producing aluminum master alloy products with suitable shapes is convenient for subsequent application in the casting and melting of aluminum alloys, improving the processability and material properties of aluminum alloys.

[0026] The present invention adopts water cooling and air cooling methods to rapidly cool and form aluminum master alloy liquid. During the cooling and forming process, the aluminum master alloy liquid does not come into contact with water, and the obtained aluminum master alloy product has no water marks and moisture, featuring high product quality, large-scale continuous production, and high production efficiency.
