Description

Technical Field

[0001] The utility model relates to a device for preventing a nozzle quick-change mechanism from driving an oil cylinder from top deviation, and belongs to the technical field of steelmaking equipment in the metallurgical industry. Background Art

[0002] The tundish is a crucial piece of equipment in the continuous casting process of steelmaking. Its primary function is to control the flow of molten steel within the tundish through its nozzle quick-change mechanism. This flow is controlled by changing the nozzle, which is powered by a drive cylinder. To ensure the nozzle can be accurately positioned, the drive cylinder's piston rod must align with the nozzle's horizontal centerline, ensuring smooth and precise nozzle operation.

[0003] Currently, during the continuous casting process, the quick-change nozzle is mounted on a cylinder bracket. The operator manually controls the cylinder tubing, visually confirms the alignment of the nozzle and the cylinder centerline, activates the cylinder, and pushes the nozzle into the pouring position. This method is inconvenient and requires lengthy adjustments. It also fails to ensure perfect alignment between the nozzle and the cylinder centerline. Consequently, the cylinder frequently pushes against the upper guide plate or nozzle outlet, causing it to misalign. This misalignment can lead to steel punctures in the tundish quick-change mechanism, potentially halting continuous casting production or causing molten steel to burn and damage the tundish quick-change mechanism and the continuous casting equipment. Utility Model Content

[0004] The purpose of the utility model is to provide a device to prevent the nozzle quick-change mechanism from driving the oil cylinder top deviation, effectively avoiding the steel puncture accident of the ladle quick-change mechanism caused by the driving oil cylinder top deviation, ensuring personal and equipment safety, and solving the problems existing in the background technology.

[0005] The technical solution of the utility model is:

[0006] When auger locks, auger locks, and ...

[0007] The top beam, the connecting rod and the handle are connected into an integrated structure.

[0008] The top beam, connecting rod and handle connected into an integral structure are located between the upper guide plate and the driving oil cylinder.

[0009] The size of the top beam matches the distance between the upper guide plate and the driving oil cylinder to ensure that the water outlet to be installed completely coincides with the center line of the driving oil cylinder.

[0010] The beneficial effects of the utility model are:

[0011] (1) The accuracy requirement for the complete coincidence between the water outlet and the center line of the driving cylinder has been improved, effectively avoiding the steel puncture accident of the tundish quick-change mechanism caused by the top deviation of the driving cylinder, and ensuring the safety of personnel and equipment;
