Description

Technical Field

[0001] This invention relates to the field of semi-continuous casting, and in particular to an apparatus and method for deep reheat semi-continuous casting of aluminum alloys. Background Technology

[0002] Currently, aluminum alloy casting typically employs a direct-cooling semi-continuous casting process to produce round and flat ingots. Liquid aluminum melt is poured into the space enclosed by a crystallizer and a sprue head. When the aluminum melt comes into contact with the crystallizer and sprue head, it is cooled by the crystallizer and sprue head and solidifies along their boundaries.

[0003] In related technologies, a semi-continuous deep reheating casting device for aluminum alloys includes a crystallizer and an tundish positioned above the crystallizer. The tundish is externally encased in a heating coil. A siphon rod is located at the bottom of the crystallizer. The crystallizer and the tundish are connected via a pipette. A flow regulating cone for sealing the pipette is slidably installed in the tundish. An electric telescopic rod is fixedly connected to the tundish, with its extended end fixedly connected to the flow regulating cone. An inlet pipe is located at the top of the tundish. When casting aluminum alloy, molten aluminum alloy is first injected into the tundish through the inlet pipe. Then, the electric telescopic rod is activated, causing the flow regulating cone to move, allowing the molten aluminum alloy to enter the crystallizer through the pipette and undergo cooling and casting within the crystallizer. Finally, the solidified aluminum alloy is pulled out using the siphon rod.

[0004] Regarding the aforementioned technologies, during the process of molten aluminum alloy entering the crystallizer through a pipette, due to the temperature difference between the tundish and the crystallizer, the molten aluminum alloy is prone to forming a condensation layer or impurities on the pipette wall. This not only reduces the effective flow area of ​​the pipette but also leads to unstable flow of the molten aluminum alloy, thereby affecting the casting efficiency of the aluminum alloy. Summary of the Invention

[0028] The following is in conjunction with the appendix Figure 1 - Appendix Figure 10 The present invention will be described in further detail below.

[0029] This invention discloses an apparatus and method for deep tempering semi-continuous casting of aluminum alloys. (Refer to...) Figures 1 to 3The aluminum alloy deep reheat semi-continuous casting apparatus includes a tundish 1, a crystallizer 2, a pipette 11 fixedly connected between the tundish 1 and the crystallizer 2, a flow regulating cone 12 for sealing the pipette 11, an electric telescopic rod 13 fixedly connected to the tundish 1, an inlet pipe 14 fixedly connected to the tundish 1, a siphon rod 21 installed in the crystallizer 2, and an adjusting mechanism 3. The extended end of the electric telescopic rod 13 is fixedly connected to the flow regulating cone 12. The adjusting mechanism 3 includes an adjusting rod 31 disposed in the pipette 11 and a support platform 32 slidably installed in the crystallizer 2. The adjusting rod 31 contacts the inner wall of the pipette 11 and is mounted on the support platform 32. The crystallizer 2 is equipped with a sliding mechanism 4 for driving the support platform 32 to move and a rotating mechanism 4 for driving the support platform 32 to rotate. The rotating component is used to process aluminum alloys. First, molten aluminum alloy is injected into the tundish 1 through the inlet pipe 14. Then, the electric telescopic rod 13 is activated, causing the flow regulating cone 12 to move upwards. The molten aluminum alloy enters the crystallizer 2 through the pipette 11 for solidification. After a certain amount of molten aluminum alloy is injected into the crystallizer 2, the flow regulating cone 12 moves downwards to seal the pipette 11. Then, the sliding mechanism 4 is activated, moving the support platform 32 below the pipette 11. Next, the rotating component is activated, causing the support platform 32 to rotate. The support platform 32 then rotates the regulating rod 31, which cleans the wall of the pipette 11, thus solving the problem of affecting the casting efficiency of the aluminum alloy.

[0030] Reference Figure 3 A cleaning rod 33 is rotatably mounted on the support platform 32. The cleaning rod 33 is in contact with the conical surface of the flow regulating cone 12. A flipping component for driving the cleaning rod 33 to rotate is installed in the support platform 32. During the rotation of the support platform 32, the support platform 32 drives the cleaning rod 33 to rotate. The cleaning rod 33 cleans the conical surface at the bottom of the flow regulating cone 12, further solving the problem of affecting the casting efficiency of aluminum alloy.

[0031] Reference Figure 3 and Figure 8 An adjusting push rod 311 is provided at the end of the adjusting rod 31 away from the support platform 32. An adjusting spring 312 is fixedly connected between the adjusting push rod 311 and the adjusting rod 31. The adjusting push rod 311 contacts the inner wall of the pipette 11 and abuts against the conical surface of the flow regulating cone 12. This increases the contact area between the adjusting rod 31 and the pipette 11 wall, making the pipette 11 cleaner.

[0032] Reference Figures 3 to 9The adjusting rod 31 is rotatably mounted on the support platform 32. The flipping component can drive the adjusting rod 31 to rotate. The adjusting rod 31 is equipped with a locking component for locking the adjusting push rod 311. When the adjusting rod 31 is not in use, the adjusting rod 31 can be stored on the support platform 32 to avoid affecting the flow of molten aluminum alloy.

[0033] The adjusting rod 31 has a sliding groove for the adjusting push rod 311 to slide. An installation groove is formed on the inner wall of the sliding groove. The locking component includes a locking spring 313 fixedly connected to the inner wall of the installation groove and a locking block 314 slidably installed in the installation groove. The locking spring 313 and the locking block 314 are fixedly connected. The adjusting push rod 311 has a locking groove for the locking block 314 to be inserted into. A locking bevel is formed on the end face of the locking block 314 that can contact the adjusting push rod 311. A locking push rod 315 passes through the adjusting rod 31 and extends into the installation groove. The locking block 314 has an unlocking groove for the locking push rod 315 to be inserted into. The unlocking groove is formed near the inner wall of the locking spring 313. The device has an unlocking ramp that contacts the locking push rod 315, which can contact the inner wall of the pipette 11. When the adjusting rod 31 is retracted onto the support platform 32, the adjusting rod 31 separates from the inner wall of the pipette 11, the locking push rod 315 extends from the adjusting rod 31, and the locking block 314 extends from the mounting groove. During the flipping process of the adjusting rod 31, the adjusting push rod 311 slides along the conical surface of the flow regulating cone 12. When the adjusting push rod 311 abuts against the locking ramp, the adjusting push rod 311 pushes the locking block 314 to move. When the locking block 314 is opposite to the locking groove, the locking spring 313 pushes the locking block 314 into the locking groove, thereby locking the adjusting push rod 311.
