[0002] The stopper rod is a refractory rod installed in the ladle to control the opening and closing of the water inlet and the flow of molten steel by lifting and displacement. It is also called a ceramic stopper rod. It consists of a rod core, sleeve bricks and plug head bricks. The rod core is usually made of ordinary carbon steel round steel with a diameter of 30 to 60 mm.

[0003] The upper end of the existing multi-channel stopper rod is connected to the cross arm of the lifting mechanism by multiple sets of bolts, and the lower end is connected to the plug brick by threads or pins. The multi-channel stopper rod is relatively heavy. When connected to the cross arm, it is necessary to keep the screw holes of the connecting ears on the upper end of the multi-channel stopper rod aligned with the screw holes on the cross arm, and then screw in the bolts in turn to fix them. The overall installation process needs to ensure that the installation screw holes will not be misaligned, and it also requires the cooperation of multiple people, making the installation work more troublesome and time-consuming.
