Description

Technical Field

[0001] This utility model relates to the field of steel ladle technology, specifically a steel ladle with a sliding sprue structure for casting in a central trough. Background Technology

[0002] A ladle is a container used to transport and pour molten metal. When using a ladle, a sliding gate is needed to control the flow rate of molten steel.

[0003] A search revealed that patent CN222970980U discloses a replaceable sliding gate for steel ladles, including a motor. Users can adjust the position of the first adjusting block via the motor according to their production needs, thereby adjusting the opening. The motor effectively reduces manual intervention, making the opening adjustment more precise. After the sliding gate stops operating, the first adjusting block will reset. During this reset process, molten steel dripping onto the top of the first adjusting block will be scraped off by the blade on the mounting base. This reduces manual intervention and prevents residual molten steel on the top of the first adjusting block from affecting the internal structure of the sliding gate. After prolonged use, users can remove it from the fixing slot by rotating the mounting base for replacement.

[0004] However, the aforementioned patent requires disassembling four sets of first knobs and four sets of second knobs to remove and replace the first and second adjustment blocks, which is quite cumbersome. Summary of the Invention

[0019] The molten metal inside the ladle body 1 flows into the square shell 2 and is discharged from the pipe in the bottom support 703 through the through holes of the lower slide plate 4 and the upper slide plate 3. The hydraulic rod 6 is activated to extend it and offset the lower slide plate 4 and the upper slide plate 3 to cut off the molten metal. After the base support 703 is opened, when the lower slide plate 4 is removed downwards, the insert block 5 slides down from the output end of the hydraulic rod 6, quickly separating the hydraulic rod 6 from the lower slide plate 4.

The closing mechanism 7 includes a cross-shaped opening 701 at the bottom of the square shell 2 for receiving the insert plate 702. The insert plate 702 for limiting is slidably connected in the cross-shaped opening 701. The bottom of the insert plate 702 is connected to a bottom support 703 for closing the square shell 2. The bottom support 703 abuts against the bottom of the square shell 2. A limiting plate a704 for limiting is engaged inside the insert plate 702. The limiting plate a704 is slidably connected to the inner wall of the cross-shaped opening 701. A toothed plate 705 for moving the limiting plate a704 is connected to one side of the limiting plate a704. A gear 706 for moving the toothed plate 705 is meshed on the toothed plate 705. The gear 706 passes through and is rotatably connected to the inner wall of the square shell 2. The front part of the gear 706 is connected to a hydraulic motor 707 for rotating the gear 706 via a coupling. The hydraulic motor 707 is connected to the front part of the square shell 2.

[0021] Start the hydraulic motor 707, which drives the gear 706 to rotate. The gear 706 drives the two sets of toothed plates 705 to slide together, pull the limit plate a704 out of the insert plate 702, remove the base 703, and open the square shell 2.

[0022] exist Figure 1 and Figures 3-6 In the middle, the limiting mechanism 8 includes a slide groove 801 opened on the upper part of the inner wall of the square shell 2 for sliding the vertical plate 802. The vertical plate 802 for driving the H-shaped plate 803 to move is slidably connected on the inner wall of the slide groove 801. The vertical plate 802 is connected to the upper surface of the toothed plate 705, and the H-shaped plate 803 for driving the limiting plate b805 to move is connected above the vertical plate 802. The H-shaped plate 803 is slidably connected to the upper surface of the square shell 2.

The H-shaped plate 803 is connected to the front and rear toothed plates 705 through the two sets of vertical plates 802. When the front toothed plate 705 slides, the rear toothed plate 705 slides synchronously.

The limiting plate b805 is connected to one side of the H-shaped plate 803.

[0025] When the toothed plate 705 slides, it drives the upright plate 802 to slide in the slide groove 801. The upright plate 802 drives the H-shaped plate 803 to move. The H-shaped plate 803 drives the two sets of limiting plates b805 to be pulled out from the corresponding lifting plate 804, releasing the limitation on the lifting plate 804. At this time, the upper slide plate 3 can be taken out downward.

[0026] In use, the hydraulic rod 6 is first extended to stagger and seal the holes in the lower slide plate 4 and the upper slide plate 3. Then, molten metal is poured into the ladle body 1, and the ladle body 1 is hoisted to the top of the mold. The hydraulic rod 6 is then shortened to align the holes in the upper slide plate 3 and the lower slide plate 4, allowing the molten metal in the ladle body 1 to be discharged through the holes in the upper slide plate 3 and the lower slide plate 4 from the pipe in the base 703. Then, the hydraulic rod 6 is extended again to throttle the flow, and the ladle body 1 is hoisted to the top of another mold to discharge the molten metal again. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
