Description

Technical Field

[0001] This utility model belongs to the field of metallurgical equipment technology, and in particular relates to a stopper rod mechanism connector. Background Technology

[0002] In the continuous casting process of billet mill in steelmaking plants, molten steel needs to be poured from the tundish to the crystallizer. Although the existing stopper rod connection device can meet the current production needs, the connection method is complicated and the installation is cumbersome. After the casting time exceeds ten heats of steel, the probability of the stopper rod loosening increases significantly. It is impossible to accurately control the amount of molten steel injected into the crystallizer. Moreover, due to the lack of argon blowing design, for some steel grades, the tundish nozzle of the billet is prone to nodule formation, causing accidents and casting stoppages.

[0003] Meanwhile, some stoppers are quite heavy, making them very difficult for personnel to install, and there are few lifting points during hoisting, making it troublesome to use equipment for lifting. Summary of the Invention

[0004] The purpose of this utility model is to provide a stopper rod mechanism connector. The stopper rod connector is tightly connected by the cooperation of multiple layers of spherical and flat washers, which can prevent the stopper rod from loosening and shifting during the steel casting process. The argon blowing channel left between the stopper rod and the connecting shaft ensures smooth argon blowing and avoids the problem of nozzle nodule formation. The design of the lifting ring facilitates lifting and installation, and the cooperation of the hook body and the locking ring can play a role in preventing detachment, thereby improving stability and safety.
