Description

Technical Field

[0001] The utility model relates to the technical field of a water inlet quick-change mechanism, and more specifically to a blind plate bracket driving device. Background Art

[0002] At present, in the process of continuous steel casting, when the tundish is operating normally online and casting steel, a blind plate will be installed next to the immersed downspout of the tundish water inlet quick-change mechanism. In the event of a casting accident, the oil cylinder of the tundish water inlet quick-change mechanism can be used to push in the blind plate to instantly cut off the steel flow, providing the basic conditions for emergency handling of accidents. The blind plate can also be used to cut off the residual flow of molten steel at the end of casting, which is conducive to safe and civilized production.

[0003] In the process of continuous steel casting, when the intermediate tank water inlet quick-change mechanism replaces the immersed water inlet, the traditional method is to use manual operation to take out the blind plate from the preparation position of the water inlet quick-change mechanism and put in the new immersed water inlet to be replaced. After the oil cylinder of the water inlet quick-change mechanism pushes the new immersed water inlet into the working position to complete the replacement, the blind plate is manually put into the water inlet quick-change mechanism.

[0004] In the process of the oil cylinder of the nozzle quick-change mechanism pushing the new submerged nozzle into the working position, if the nozzle joint surface is in poor condition or other reasons cause steel to slip, the blind plate cannot be manually put into the nozzle quick-change mechanism, and the casting flow cannot be cut off by operating the oil cylinder of the nozzle quick-change mechanism to push the blind plate in. If the stopper rod of the intermediate tank flow control cannot close the nozzle at this time, this situation is dangerous and poses a safety hazard. Utility Model Content

[0032] like Figure 2 As shown, during normal continuous casting operation, the blind plate bracket 6 is in the closed position, and the blind plate 7 on the blind plate bracket 6 occupies the new submerged water outlet preparation position 10a next to the submerged water outlet 10 of the normal casting working position. When an emergency occurs during the casting process, the oil cylinder of the water outlet quick-change mechanism can be used to push the blind plate 7 into the submerged water outlet 10 to instantly cut off the steel flow.
