Stopper
Accurate Flow Control
Precisely adjust the gap between the stopper head and nozzle to regulate molten steel flow, ensuring stable pouring and consistent casting quality.
Excellent Oxidation Resistance
Enhanced sealing and high-density structure effectively block air ingress, reducing oxidation and inclusion formation.
Prevention of Vortices and Slag Entrapment
Engineered design minimizes vortex formation and prevents slag from entering the nozzle, maintaining clean molten steel flow.
High Strength & Erosion Resistance
Manufactured with high-quality raw materials and isostatic pressing technology to deliver exceptional strength, wear resistance, and extended service life.
