AI Technical Summary
In casting and rolling production, due to the pile heat effect of aluminum liquid, the temperature of aluminum liquid located in the middle of the casting nozzle is much higher than the temperature of aluminum liquid located at both ends of the casting nozzle, resulting in problems such as element segregation and varying grain size of the plate, resulting in uneven plate structure and reduced mechanical properties of the plate.
A high-speed wide-width casting and rolling device with partition temperature control function is designed. By providing a diversion assembly and partition structure in the casting nozzle, liquid aluminum is staggeredly diverted between the lower nozzle fan and the first partition and the second partition and the upper nozzle fan, reducing the stacking heat effect and making the temperature of each flow-guiding partition the same.

Compared with steel casting technology, non-ferrous metal casting technology such as aluminum and magnesium is more mature and more industrialized. Taking aluminum as an example, industrial casting and rolling production of 1 series, 3 series, 8 series, and some alloys in 5 series and 6 series has been achieved. Therefore, twin-roll casting technology has become an internationally recognized key development direction in the future, and has shown outstanding advantages in the solid-liquid casting and rolling of heterogeneous metal layered composite materials.
[0003] At present, in the casting and rolling production of aluminum alloys, a casting nozzle is required to discharge the molten metal onto the casting and rolling machine for production.
[0004] For example, a casting nozzle structure for aluminum casting and rolling coil production provided by announcement number CN221312423U includes an upper plate and a lower plate, a retaining edge is provided between the upper plate and the lower plate, a casting cavity is formed between the retaining edge and the upper plate and the lower plate, the casting cavity is connected with a casting and rolling feed port connected to the outside and opened at one end of the retaining edge and a casting and rolling discharge port opened at the other end of the retaining edge, an even number of guide plates are provided in the casting cavity, the upper end of which is connected to the upper plate and the lower end is connected to the lower plate, the guide plates are arranged symmetrically on both sides of the casting and rolling feed port, and the guide plates are in a closed ring shape; among all the guide plates located on the left side, the left guide plate of the two adjacent guide plates can be embedded in the center of the right guide plate; among all the guide plates located on the right side, the right guide plate of the two adjacent guide plates can be embedded in the center of the left guide plate. The casting nozzle structure has the characteristics of light weight, material saving, complete overall function and strong practicality.

The casting nozzle for producing aluminum plates by the casting and rolling method is equipped with a rotating mechanism, wherein the position of the screw is limited by a through groove and a top plate, so as to facilitate supporting the screw, the position of the nut is limited by the screw, so as to facilitate rotating the nut to fix the screw, and the position of the gripping block is limited by the screw, so as to facilitate rotating the screw, thereby fixing the top plate with the size of the casting nozzle adjusted.
[0006] However, when the above technology is actually used, due to the heat accumulation effect of the aluminum liquid, the temperature of the aluminum liquid in the middle of the casting nozzle will be much higher than the temperature of the aluminum liquid at both ends of the casting nozzle, which will cause element segregation and uneven grain size of the plate, resulting in uneven plate structure and reduced mechanical properties of the plate.

The two ends of the top of the upper nozzle fan 5 are respectively fixedly installed with arc-shaped positioning pieces 11. The inner wall of the cover plate 9 corresponding to the position of the arc-shaped positioning piece 11 is provided with a positioning groove 12, and the arc-shaped positioning piece 11 is rotatably connected to the inner wall of the positioning groove 12. The arc centers of the arc-shaped positioning piece 11, the positioning groove 12 and the top of the support bar 3 are located on the same horizontal line.

The surface of the threaded tube 17 is connected with a threaded tube 17. A driving wheel 20 is fixedly installed on the top of the surface, so that when the threaded tube 17 is driven to rotate by the driving wheel 20, the threaded tube 17 is threadedly connected with the screw 15 and drives the upper nozzle fan 5 to rotate around the arc structure at the top of the support bar 3 through the screw 15 and the hinge block 14, thereby adjusting the outlet width of the discharge cavity between the lower nozzle fan 1 and the upper nozzle fan 5.

[0056] like Figure 5 and 6 The flow diversion component includes a first baffle plate 801 and a first guide plate 802, which are fixedly installed between the lower nozzle fan 1 and the first partition plate 2 and between the second partition plate 4 and the upper nozzle fan 5, and a molten aluminum flow channel is formed between the first baffle plate 801 and the first guide plate 802 and between the adjacent first guide plates 802, the first baffle plate 801 between the lower nozzle fan 1 and the first partition plate 2 is located at both ends, and the multiple first baffle plates 801 between the lower nozzle fan 1 and the first partition plate 2 are respectively located in the middle, so that the molten aluminum is located between the lower nozzle fan 1 and the first partition plate 2 and diverted from the middle;

[0058] The aluminum liquid between the lower nozzle fan 1 and the first partition plate 2 and between the second partition plate 4 and the upper nozzle fan 5 finally converges in the discharge cavity between the lower nozzle fan 1 and the upper nozzle fan 5;
[0059] When the above structure is in use, the high-temperature aluminum liquid enters the interior of the cover plate 9 through the feed port 10, and enters the position between the lower nozzle fan 1 and the first partition 2 and the second partition 4 and the upper nozzle fan 5 through the gap in the middle of the first guide bar 6 and the second guide bar 7, and is guided by the first baffle plate 801 and the first guide plate 802, so that the aluminum liquid between the lower nozzle fan 1 and the first partition 2 is diverted from the middle, and the aluminum liquid between the second partition 4 and the upper nozzle fan 5 is diverted from both ends, and finally the aluminum liquid between the lower nozzle fan 1 and the first partition 2 and between the second partition 4 and the upper nozzle fan 5 converges in the discharge cavity between the lower nozzle fan 1 and the upper nozzle fan 5. It should be noted that in the case of pile heating;
[0060] First, the aluminum liquid between the lower nozzle fan 1 and the first partition 2 is diverted from the middle, and the heat dissipation in the middle is slow;
[0061] The aluminum liquid between the second partition plate 4 and the upper nozzle fan 5 is divided into two large streams and flows from both ends. Each stream of aluminum liquid forms a new heat center of the pile and is further diverted by the multiple first guide plates 802.

[0068] Finally, the aluminum liquid between the lower nozzle fan 1 and the first baffle 2 and between the second baffle 4 and the upper nozzle fan 5 converges in the discharge chamber between the lower nozzle fan 1 and the upper nozzle fan 5, so that after the aluminum liquid between the lower nozzle fan 1 and the first baffle 2 and between the second baffle 4 and the upper nozzle fan 5 converges in the discharge chamber between the lower nozzle fan 1 and the upper nozzle fan 5, the temperature difference of the aluminum liquid inside the entire discharge chamber is small, thereby avoiding the occurrence of uneven plate structure and reduced mechanical properties of the plate.

[0072] The flow rate of the aluminum liquid flowing through the position between two adjacent second guide plates 804 and the baffle block 805 is greater than the flow rate of the aluminum liquid flowing through the position between two adjacent second baffle plates 803, and the aluminum liquid flows through the fast diversion channel and the slow diversion channel between the lower nozzle fan 1 and the first baffle plate 2 and between the second baffle plate 4 and the upper nozzle fan 5, and the aluminum liquid between the lower nozzle fan 1 and the first baffle plate 2 and between the second baffle plate 4 and the upper nozzle fan 5 finally converges in the discharge cavity between the lower nozzle fan 1 and the upper nozzle fan 5;
[0073] When the above structure is used, first, when the aluminum liquid is located in the diversion channel at the position of the second guide plate 804 and the baffle block 805, the flow rate is slow, and when the aluminum liquid is located in the diversion channel at the position of the adjacent second baffle plate 803, the flow rate is fast;
[0074] The aluminum liquid between the lower nozzle fan 1 and the first partition plate 2 is rapidly diverted from the middle and slowly diverted from both ends;
[0075] The aluminum liquid between the second partition plate 4 and the upper nozzle fan 5 is rapidly diverted from both ends and slowly diverted from the middle;
[0076] The slow shunt area and the fast shunt area between the lower nozzle fan 1 and the first baffle 2 correspond to the fast shunt area and the slow shunt area between the second baffle 4 and the upper nozzle fan 5, respectively. In the whole shunt process, the slow shunt is used as a temperature transition area. Since the aluminum liquid stays between the lower nozzle fan 1 and the first baffle 2 and between the second baffle 4 and the upper nozzle fan 5 for a long time, it can achieve the purpose of transition heat exchange, that is, the temperature of the aluminum liquid flowing out of the lower nozzle fan 1 and the first baffle 2 and the second baffle 4 and the upper nozzle fan 5 through the fast shunt channel will not differ much;
[0077] Finally, the aluminum liquid between the lower nozzle fan 1 and the first baffle 2 and between the second baffle 4 and the upper nozzle fan 5 converges in the discharge chamber between the lower nozzle fan 1 and the upper nozzle fan 5, so that the aluminum liquid between the lower nozzle fan 1 and the first baffle 2 and between the second baffle 4 and the upper nozzle fan 5 converges in the discharge chamber between the lower nozzle fan 1 and the upper nozzle fan 5. The temperature difference of the aluminum liquid inside the entire discharge chamber is small, thereby avoiding the occurrence of uneven plate structure and reduced mechanical properties of the plate. Compared with Example 1, the effect of the zoned temperature control achieved is better than that of Example 1.
[0078] Embodiment 4
[0079] like Fig.11 and 12 , which is different from the third embodiment:
[0080] The second baffle plate 803 and the second guide plate 804 between the lower nozzle fan 1 and the first baffle plate 2 are staggered with the second baffle plate 803 and the second guide plate 804 between the second baffle plate 4 and the upper nozzle fan 5, so that the split flow of the aluminum liquid between the lower nozzle fan 1 and the first baffle plate 2 and the split flow of the aluminum liquid between the second baffle plate 4 and the upper nozzle fan 5 are staggered with each other;
[0081] The aluminum liquid between the lower nozzle fan 1 and the first partition plate 2 and between the second partition plate 4 and the upper nozzle fan 5 finally converges in the discharge cavity between the lower nozzle fan 1 and the upper nozzle fan 5;
[0082] When the above structure is in use, the aluminum liquid between the lower nozzle fan 1 and the first partition plate 2 and between the second partition plate 4 and the upper nozzle fan 5 first flows through a plurality of slow shunt channels and a fast shunt channel. The slow shunt area and the fast shunt area between the lower nozzle fan 1 and the first partition plate 2 correspond to the fast shunt area and the slow shunt area between the second partition plate 4 and the upper nozzle fan 5, respectively, so that the temperature difference between the plurality of shunt channels is small.
[0083] Finally, the aluminum liquid between the lower nozzle fan 1 and the first baffle 2 and between the second baffle 4 and the upper nozzle fan 5 converges in the discharge chamber between the lower nozzle fan 1 and the upper nozzle fan 5, so that after the aluminum liquid between the lower nozzle fan 1 and the first baffle 2 and between the second baffle 4 and the upper nozzle fan 5 converges in the discharge chamber between the lower nozzle fan 1 and the upper nozzle fan 5, the temperature difference of the aluminum liquid inside the entire discharge chamber is small, thereby avoiding the occurrence of uneven plate structure and reduced mechanical properties of the plate. Compared with Example 3, the arrangement of the second baffle plate 803, the second guide plate 804 and the baffle block 805 is reasonably divided, and the accuracy and temperature control effect of the zoned temperature control are better than those of Example 3.
