The function of the integral stopper is mainly used to control the flow of the tundish. The integral stopper rod is installed in the tundish when in use. The flow of molten steel into the crystallizer can be adjusted by controlling the position of the stopper head to the tundish nozzle, and argon or other inert gas can also be blown into the tundish through the argon blowing hole to prevent the nozzle Clogged.
