Tundish Stopper
MOQ: 100 pieces
Description
Tundish stopper is composed of rod core, sleeve brick and plug brick. The rod core is usually made of plain carbon steel round steel with a diameter of 30-60mm. The upper end is connected with the cross arm of the lifting mechanism by bolts, the lower end is connected with the plug brick by threads or pins, and the middle sleeve brick. Tundish stopper must be carefully built and used after baking and drying for more than 48 hours to avoid breakout accidents caused by refractory explosions.
The integral stopper rod is installed in the tundish when in use. The flow rate of molten steel entering the mold can be adjusted by controlling the position of the stopper rod head to the tundish nozzle, and argon can also be blown to the tundish through the argon blowing hole to prevent the nozzle from being blocked.
Features
Good erosion resistance / Corrosion resistance / Stable flow control during casting / Close tightly after casting
