When the mounting base roller 14 and the lower track roller 23 rotate at the same time, the track 31 moves between the mounting base roller 14 and the lower track roller 23. The gear column plate 33 has two gear column plates for fixing the gear column 32, and a row of through holes for fixing the gear column 32 are arranged on the side surface of the gear column plate 33.

The track end plate 34 is located at both ends of the track assembly 3, one side of the track end plate 34 is used for fixing the track 31 and the gear column plate 33, and the other side is provided with a mounting hole for connecting with the machine tool base. The machine tool base is a platform for fixing and supporting various machines and equipment. In this embodiment, when the liquid core tracking stirrer is used to stir the casting blank melt, the track 31 is fixed on the machine tool base.

[0052] The track 31 and the gear column plate 33 are both arc-shaped, so the overall track assembly 3 is arc-shaped. The central angle of the circle corresponding to the arc-shaped track assembly 3 is angle A. In this embodiment, the size of angle A is 5° to 20°.

[0053] As shown in Figure 3 and Figure 9 , the driving assembly 4 comprises a driving mounting arm 41, a driving mounting plate 42, a driving bearing seat 43, a driving gear 44, a driving shaft 45, a first transmission gear 46, a second transmission gear 47, a motor mounting seat 48 and a hydraulic motor 49.

[0054] The driving mounting arm 41 is fixed on both ends of the driving mounting plate 42. The side surface upper end of the driving mounting arm 41 is provided with a mounting hole, which is connected with the mounting hole provided on the side surface lower end of the lower track wheel mounting arm 21 through a bolt.

[0055] The driving bearing seat 43 is fixed on the driving mounting plate 42 close to one side of the lower track wheel assembly 2 and is located at the middle position of the driving mounting plate 42. The driving shaft 45 is installed on the driving bearing seat 43, and the driving gear 44 is fixed at the middle position of the driving shaft 45 and rotates with the driving shaft 45. In order not to limit the rotation of the driving gear 44, a gap hole is provided on the driving mounting plate 42 close to the lower position of the driving gear 44, and the peripheral teeth of the driving gear 44 pass through the gap hole when the driving gear 44 rotates, but do not touch the driving mounting plate 42. As shown in the figure, the driving gear 44 is engaged with the gear column 32 of the track assembly 3, and since the track assembly 3 is fixed, when the driving gear 44 rotates, the entire driving assembly 4 moves along the track assembly 3. Figure 2

[0056] The first transmission gear 46 is fixed on one end of the driving shaft 45 and is located on one side of the driving bearing seat 43. The motor mounting seat 48 is fixed on the driving mounting plate 42 away from one side of the lower track wheel assembly 2, and the hydraulic motor 49 is installed on the motor mounting seat 48. The motor mounting seat 48 is provided with a through hole, and the hydraulic motor 49 is connected with the second transmission gear 47 through the through hole. The driving mounting plate 42 is provided with a through hole close to the lower position of the first transmission gear 46, and the first transmission gear 46 is engaged with the second transmission gear 47 through the through hole.

[0057] When the hydraulic motor 49 works, the hydraulic motor 49 drives the second transmission gear 47 to rotate, the second transmission gear 47 drives the first transmission gear 46 to rotate, the first transmission gear 46 drives the driving gear 44 to rotate through the driving shaft 45, the driving gear 44 is engaged with the gear column 32 of the track assembly 3, and the driving assembly 4 moves along the track assembly 3. In this embodiment, the hydraulic motor 49 can rotate forward and reverse, and when the hydraulic motor 49 works, the driving gear 44 can rotate forward and reverse under the drive of the hydraulic motor 49, so that the whole formed by the mounting seat assembly 1, the lower track wheel assembly 2, the driving assembly 4 and the electromagnetic stirrer 5 moves back and forth along the track assembly 3, thereby realizing the movement within the angle A range.

[0058] As shown in the figure, the driving gear 44 is engaged with the gear column 32 of the track assembly 3, and since the track assembly 3 is fixed, when the driving gear 44 rotates, the entire driving assembly 4 moves along the track assembly 3. Figure 10 ​As shown, the present embodiment adopts a liquid core tracking stirrer to conduct electromagnetic stirring on the casting blank, so as to improve the quality of the casting blank. The liquid core tracking stirrer is arranged at the terminal position of the secondary cooling zone of the square-round blank continuous casting machine (the secondary cooling zone is the secondary cooling zone of the casting blank).

[0059] The mounting seat assembly 1 is bolted with the lower track wheel assembly 2, and the track assembly 3 is installed between the mounting seat assembly 1 and the lower track wheel assembly 2. The upper end of the track 31 of the track assembly 3 is in contact with the mounting seat roller 14 of the mounting seat assembly 1, and the lower end is in contact with the lower track roller 23 of the lower track wheel assembly 2. The driving assembly 4 is bolted with the lower track wheel assembly 2, so that the driving gear 44 of the driving assembly 4 is engaged with the gear column 32 of the track assembly 3. According to the position of the casting blank, the two ends of the track assembly 3 are fixed on the machine tool base, and the position of the track assembly 3 is adjusted so that the arc direction of the track assembly 3 conforms to the casting direction of the casting blank. The electromagnetic stirrer 5 is bolted with the mounting seat assembly 1, so that the casting blank passes through the electromagnetic stirrer 5.

[0060] The electromagnetic stirrer 5 is started to work. During the process of using the electromagnetic stirrer 5 to conduct electromagnetic stirring on the casting blank, it is determined whether the position of the electromagnetic stirrer 5 needs to be adjusted according to the specific production requirements and process conditions. When the position of the electromagnetic stirrer 5 needs to be adjusted, the hydraulic motor 49 of the driving assembly 4 is started, and after the position to be adjusted is determined, the hydraulic motor 49 drives the whole formed by the connection of the mounting seat assembly 1, the lower track wheel assembly 2, the driving assembly 4 and the electromagnetic stirrer 5 to move along the track assembly 3 to the position to be adjusted.

[0061] Specifically, the hydraulic motor 49 drives the second transmission gear 47 to rotate. Since the first transmission gear 46 is engaged with the second transmission gear 47, the second transmission gear 47 drives the first transmission gear 46 to rotate. Since the first transmission gear 46 and the driving gear 44 are simultaneously installed on the driving shaft 45, the first transmission gear 46 drives the driving gear 44 to rotate through the driving shaft 45. The driving gear 44 is engaged with the gear column 32 of the track assembly 3. Since the track assembly 3 is fixed on the machine tool base, its position does not change. The rotation of the driving gear 44 drives the driving assembly 4 to move along the track assembly 3, and the whole formed by the connection of the mounting seat assembly 1, the lower track wheel assembly 2, the driving assembly 4 and the electromagnetic stirrer 5 moves along the track assembly 3. Among them, the mounting seat roller 14 and the lower track roller 23 rotate and move along the track 31 at the same time. The driving gear 44 moves along the whole formed by the gear column 32 and the gear column plate 33. When the electromagnetic stirrer 5 moves to the position to be adjusted of the casting blank, the hydraulic motor 49 stops working.

[0062] The liquid core ratio in the casting blank of different sizes, different pulling speeds and different steel grades is different, the acting position of the electromagnetic stirrer needs to be different in the production process, and the best stirring position of the electromagnetic stirrer changes with the change of the liquid core ratio of the casting blank. By adjusting the position of the electromagnetic stirrer, the temperature distribution and flow condition in the secondary cooling zone can be changed, thereby affecting the change of the secondary cooling intensity, better meeting the process requirements, and ensuring the stability in the production process and the quality of the casting blank. In the production process, the liquid core tracking stirrer of the embodiment can adjust the position along the casting direction under the driving of the hydraulic motor 49, so that the electromagnetic stirrer 5 can be kept at the best stirring position at any time, and the stirring effect on the casting blank is better.
