[0002] The horizontal continuous casting process is often used to produce alloy varieties that are difficult to hot-roll (such as tin phosphor bronze, lead brass, etc.). It has the advantages of short process, low production cost, small floor area of equipment, low energy consumption, etc. Reasonably controlling the solidification process through the mold is the prerequisite for obtaining high-quality ingots and the basis for preparing high-performance metal materials. The mold is the core component of horizontal continuous casting and directly affects the quality and production efficiency of the billet.

[0022] Referring to Figures 2-4 Figures 2-4 , the water storage tank 4 is arranged in a funnel shape with a large top and a small bottom. A rotating shaft 41 is rotatably arranged in the water storage tank 4. A stirring rod 411 is fixedly arranged on the outer peripheral surface of the rotating shaft 41. By arranging the water storage tank 4 in a funnel shape, when the usage time of the device increases and the coolant in the water storage tank 4 decreases, the remaining coolant can be concentrated together, and the situation of incomplete use of the solution will not occur. Then, by arranging the stirring rod 411 on the outer peripheral surface of the rotating shaft 41, the solution in the water storage tank 4 is evenly mixed.

[0023] Referring to Figures 3-5 Figures 3-5 , a servo motor 44 is fixedly arranged on the outer peripheral surface of the outer shell 1 2. A long plate 441 is fixedly arranged on the output end of the servo motor 44. A limiting shaft 442 is fixedly arranged on the output end of the long plate 441. A support platform 23 is fixedly arranged on the outer wall of the outer shell 1 2. A positioning frame 231 is fixedly arranged on the support platform 23. The rotating shaft 41 is rotatably connected to the positioning frame 231. A connecting plate 43 is fixedly arranged on the outer peripheral surface of the rotating shaft 41. A sliding groove 431 is formed in the connecting plate 43. The limiting shaft 442 is slidably connected to the sliding groove 431. By arranging the long plate 441 on the output end of the servo motor 44, when the staff starts the servo motor 44, the long plate 441 fixed on its output end rotates.

Pulley 234 is fixedly arranged on the outer circumferential surfaces of both the long shaft 6 and the shaft body 233. The two pulleys 234 are connected by belt drive. During the rotation of the small gear 232, the shaft body 233 fixedly connected thereto rotates. The rotating shaft body 233 drives the pulley 234 to rotate, and the pulley 234 on the long shaft 6 is driven to rotate by the belt.

[0027] Refer to Figures 5-7 , threads are provided on the outer circumferential surface of the long shaft 6. A cleaning plate 63 is threadedly connected to the long shaft 6. A guide rod 34 parallel to the long shaft 6 is fixedly arranged on the outer shell 2 3. The cleaning plate 63 is slidably connected to the guide rod 34. During the rotation of the long shaft 6, the cleaning plate 63 threadedly connected thereto can reciprocate along the long shaft 6 to clean the outer surface of the forming die 7. The guide rod 34 arranged on the outer shell 2 3 is used to control the cleaning plate 63 not to rotate axially during movement, avoiding damage to the outer surface of the forming die 7 when the cleaning plate 63 moves.

A tooth ring 62 matching the large gear 61 is fixedly arranged on the outer circumferential surface of the forming die 7. By means of the large gear 61 arranged on the outer circumferential surface of the long shaft 6, it is realized that during the rotation of the long shaft 6, the large gear 61 can be driven to rotate. The rotating large gear 61 can drive the forming die 7 to rotate through the tooth ring 62, thereby realizing the control of the shaping of the material.

[0029] Refer to Figures 6-8 , a pin 72 is fixedly arranged at one end of the forming die 7 in the vertical direction, and a connection port 71 is provided at the other end in the vertical direction. A clamping groove 73 is provided at one end of the forming die 7 in the horizontal direction, and a clamping plate 74 is fixedly arranged at the other end. By means of the pin 72 and the connection port 71 on the forming die 7, the positioning and assembly of the forming die 7 are facilitated.

[0030] Refer to Figures 2-5 , the filter plate 33 is inclined. The inclined filter plate 33 realizes that when the coolant flows on the filter plate 33, it can flow downward and cool the forming die 7 during the flowing process.

[0031] The specific solution is as follows: When using the device, the staff first move the device to a predetermined position for fixation, and then place the material to be processed in the tubular crystallizer 5 of the device. Start the magnetic stirrer 22 and the servo motor 44 on the device. The magnetic stirrer 22 can control the rotational movement of the material in the tubular crystallizer 5, and then enter the forming die 7 that is hermetically connected to it for shaping. During the processing, start the servo motor 44, and the long plate 441 fixed on its output end rotates. The rotating long plate 441 drives the connecting plate 43 to swing through the limiting shaft 442, and at any time, the swing frequency of the connecting plate 43 is controlled by the change in the rotation speed of the servo motor 44. During the process of the servo motor 44 driving the connecting plate 43 to swing, the guide plate 241 fixedly connected to the connecting plate 43 can swing along the guide groove 24, thereby realizing the control of the swing of the nozzle 242. The nozzle 242 can uniformly cool and process the tubular crystallizer 5 during the operation of the device. And during the process of the adjusting plate 42 rotating with the rotating shaft 41, the toothed adjusting plate 42 can drive the small gear 232 to rotate. During the rotation of the small gear 232, the shaft body 233 fixedly connected to it rotates. The rotating shaft body 233 drives the pulley 234 to rotate, and drives the pulley 234 on the long shaft 6 to rotate through the belt. During the rotation of the long shaft 6, the cleaning plate 63 threadedly connected to it can reciprocate along the long shaft 6 to clean the outer surface of the forming die 7. Then, through the guide rod 34 provided on the outer shell two 3, it is ensured that the cleaning plate 63 will not rotate axially during the movement, avoiding the situation that the cleaning plate 63 damages the outer surface of the forming die 7 when moving.
