Length:2750MM-3000MM


Alumina-graphite stopper
Ladle sheel stream from splashing and oxidation as it flows into the tundish.The products could serve over 10 hours of casting.The significant characteristics of the products are re-useabie and no preheating requirement.
*Graphlc illustration:
1.Built in steel nut for convenient installation.
2.Ceramic glaze layer to prevent the material oxidation effectively.
3.Standard high quality Al-C materials having high corrosion and thermal shock resistances.
4.Porous plug to prevent the steel stream from entering the stopper.
5.Standard Al-C head materials having good slag corrosion resistance.
6.Spinel head materials have exceptional good resistance to slag corrosion.
7.Standard Mg-C head materials having good slag corrosion resistance for processing steel with Ca.
8.High quality Zr-based materials to assure good corrosion resistance at slag line.
