Trait: High refractoriness, good anti-clogging, superior resistance to thermal shock, erosion/corrosion etc. Especially the SM series of upper nozzles with ZrO2 Inserted feature high refractoriness and superior scouring resistance.

Description: Stopper system is normally used in tundish for con-casting of slab and bloom. Through adjusting the slot between the stopper and the upper nozzle, the steel flowing rate could be controlled. During the casting, there will be some erosion on the stopper and upper nozzle. So the quality of the upper nozzle is very important to tundish life. SM series of upper nozzles feature reliable performances and long service life. While working together with SM serial Monoblock Stopper, the tundish casting sequences will be improved dramatically.
