Tundish refractory monoblock stopper

The stopper is one of the important steel flow regulation components, and to meet the particularly demanding operating conditions, we manufacture thirty varieties of stoppers with customised specifications to suit the different designs of our customers' tundishes. Our  stoppers are designed to cope with the extreme thermal shock faced when regulating the molten steel flowing into the mould. The nose of our stoppers is specially engineered to withstand erosion by molten steel. The slagline is also strong enough to withstand possible chemical corrosion caused by tundish immersion. We incorporate argon into our stoppers to prevent oxygen ingression. To facilitate customisation, during our manufacturing process, we apply different mixtures of aluminia or magnesia to the nose of our stoppers for our customers, enabling them to cast various types of steel.
