[0002] Since carbon rods are resistant to high temperatures, they are currently used to seal the ladle. The sealed ladle can hold high-temperature molten steel at a temperature of about 1600°C. In the existing technology, when casting is required, the jacking structure on the outer periphery of the ladle is lifted by manpower to drive the carbon rods to separate from the plug, and the high-temperature molten steel flows into the mold below the ladle to complete the casting.

[0003] The disadvantages of the existing technology are: 1. Manual lifting makes it difficult to control the lifting speed of the carbon rod, and the high-temperature molten steel may flow unevenly into the mold below, affecting product quality; 2. The temperature of the molten steel ladle is high, and the operator is at risk of scalding, which poses a safety hazard; 3. The casting time cannot be standardized and quantitatively controlled, and product consistency cannot be guaranteed. Utility Model Content

[0024] Secondly, the present invention is described in detail with reference to schematic diagrams.

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0026] The utility model provides an automatic casting device for a molten steel ladle. When the carbon rod and the plugging port of the molten steel ladle are in a naturally compressed state, the steel wire is loose (the steel wire is not under stress), the spring compression button is pushed up, the induction light is on, and the original position of the servo motor is recorded at this time. After the blocked molten steel ladle is injected with high-temperature molten steel, the servo motor is started to rotate forward, and the carbon rod is lifted at a uniform speed. After a certain period of time, the servo motor rotates in the reverse direction, driving the carbon rod to move downward under the action of the tension spring until the servo motor stops running when the induction light is on (the carbon rod and the plugging port are in a naturally compressed state at this time, but since the carbon rod is shortened, the position of the servo motor at rest and the initial position will change). After multiple castings, when the position where the servo motor stops running and the original zero position are close to the set value, the carbon rod needs to be replaced to ensure that there is no leakage during the casting process.

[0027] Figure 1-Figure 3 The following is a schematic diagram of the structure of an automatic ladle casting device according to the present invention. Figure 1-Figure 3 The present embodiment is a ladle automatic casting device, the main body of which includes a lifting mechanism 100, a traction mechanism 200, a transmission mechanism 300 and a power mechanism 400.

[0028] The lifting mechanism 100 pulls the movable rod 140 through the tension spring 130 to lower the cross bar 150, so that the carbon rod 151 is pressed tightly against the plug of the ladle 110. Specifically, the lifting mechanism 100 includes the ladle 110, a guide frame 120 arranged on the side wall of the ladle 110, a tension spring 130 arranged on the side wall of the ladle, a movable rod 140 arranged on the top of the tension spring 130 and moving along the guide frame 120, a cross bar 150 arranged on the side wall of the movable rod 140, and a fixed plate 160 arranged on the side wall of the movable rod 140. The carbon rod 151 is provided on the side wall of the cross bar 150.

When the power is turned off, the electromagnet 312 loses its magnetism and falls. The buffer 492 buffers, the steel wire 310 relaxes and loses tension. The tension spring 130 pulls down the carbon rod 151, pressing the port of the ladle 110. At the same time, the lifting spring 464 lifts the limit groove 463, and the limit The slot 463 presses the button 462, and the sensor light 461 lights up. Specifically, the transmission mechanism 300 controls the traction action of the traction mechanism 200. In this embodiment, the transmission mechanism 300 includes a first guide wheel 320, a second guide wheel 330, a third guide wheel 340, and a steel wire 310 that passes from under the first guide wheel 320, then passes from above the second guide wheel 330, and then bypasses under the third guide wheel 340. A movable plate 311 is provided at the top of the steel wire 310, an electromagnet 312 is provided at the top of the movable plate 311, and a guide hole is provided on the side wall of the movable plate 311.

The frame 460 is provided with a downward-opening limiting groove 463, and the frame 460 is provided with a lifting spring 464 extending into the limiting groove 463. A through hole is provided at the bottom of the frame 460, and a movable block 470 passing through the through hole is provided inside the limiting groove 463. A flange plate 480 is provided at the bottom of the movable block 470. The side wall of the guide rail 440 is provided with a support frame 441, and a base is provided at the bottom of the support frame 441.

[0032] Combine Figure 1-Figure 3, a ladle automatic casting device of this embodiment has the following specific usage process: when the carbon rod 151 and the blocking port of the ladle 110 are in a naturally compressed state, the steel wire 310 is relaxed (the steel wire 310 is not under force), the spring 464 is lifted up to press the button 462, the induction light 461 is on, and the original position of the servo motor 410 is recorded at this time. When the blocked ladle 110 is filled with high-temperature molten steel, the servo motor 410 is started to rotate forward, and the carbon rod 151 is lifted at a uniform speed. After a certain period of time, the servo motor 410 runs in the reverse direction, driving the carbon rod 151 to run downward under the action of the tension spring 130, until the servo motor 410 stops running when the induction light 461 lights up (at this time, the carbon rod 151 and the plug are in a naturally compressed state, but since the carbon rod 151 is shortened, the position of the servo motor 410 at rest and the initial position will change). When, after multiple castings, the position where the servo motor 410 stops running and the original zero position are close to the set value, the carbon rod 151 needs to be replaced to ensure that there is no leakage during the casting process.
