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-useable 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.
