Description

Technical Field

[0001] The utility model belongs to the technical field of steel production, in particular to a molten steel pouring device for continuous casting. Background Art

[0002] In the process of steel smelting and continuous casting, pouring molten steel is an indispensable operation. Molten steel pouring, that is, the process of pouring molten steel from the steelmaking furnace or tundish into the continuous casting machine or casting mold, is crucial to ensure the smooth flow and precise pouring of molten steel. Water pouring controls the pouring speed and angle to ensure that the molten steel enters the mold or continuous casting equipment at an appropriate flow rate, thereby achieving uniform pouring and avoiding bubbles, inclusions or cracks. The temperature of molten steel is extremely high, but it may partially solidify during transportation and storage. Timely pouring of molten steel can reduce the risk of solidification of molten steel during transfer and maintain the fluidity of molten steel.

[0003] Traditional molten steel pouring devices, some devices rely on manual operation or simple automatic control systems. Operators need to adjust the pouring angle and speed according to actual conditions to ensure that the molten steel accurately flows into the predetermined mold or casting machine. This method usually relies on experienced operators for control.

[0004] Although existing molten steel pouring devices have been widely used in the fields of smelting and casting, the overflow and splashing of high-temperature molten steel are common safety hazards during the molten steel pouring process. Most of the existing molten steel pouring devices cannot fully protect operators and equipment, and there are high safety risks. Utility Model Content

A locking mechanism is arranged on one side of the upper part of the locking disc. During the tilting process, by adjusting the running speed and direction of the driving motor, the first rotating shaft drives the molten steel ladle to rotate. When the molten steel ladle tilts to an ideal angle, the operator activates the locking mechanism to dock a certain card slot on the locking disc with the locking mechanism, fixing the tilting angle of the molten steel ladle. At this time, the high-temperature molten steel is poured through the pouring port protection assembly to avoid overflow or splashing.

[0008] As a further embodiment of the present utility model: The locking mechanism includes a connecting seat, which is fixedly connected to the support frame. A first electric push rod is arranged on the connecting seat, and a locking block is fixedly connected to the telescopic end of the first electric push rod. When the locking block enters a certain card slot on the locking disc, mechanical locking is formed, and at this time, the position of the molten steel ladle is fixed to prevent the molten steel ladle from further rotating. When it is necessary to release the lock to adjust the position of the molten steel ladle or reset it, the first electric push rod retracts, driving the locking block to retreat, and the locking block disengages from the card slot, releasing the rotation angle of the molten steel ladle.

The inclined design is used to accelerate the flow of molten steel, ensure that the molten steel flows quickly and smoothly to the receiving device, reduce overflow and splash. The guiding and protecting plates prevent the molten steel from splashing or overflowing on both sides of the guiding groove plate. By forming a closed guiding channel, the molten steel is restricted within a safe path, providing additional protection and improving the operation safety.

[0012] As a further embodiment of the present utility model: A lifting lug is detachably connected to the upper part of the support frame. The lifting lug is used for lifting and hoisting the molten steel pouring device, facilitating the installation, transportation and maintenance of the equipment.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] According to the length of the molten steel ladle and the required pouring angle, through the electric slider on the electric slide rail, the pouring opening protection assembly is adjusted to an appropriate position, and then the specific position of the entire pouring opening protection assembly relative to the protection frame is adjusted. The driving motor is started to drive the molten steel ladle to slowly rotate until it fits the pouring opening protection assembly.
