Alumina-Graphite

We offer ISO-statically pressed carbon bonded alumina-graphite stopper rods with enhanced composition wear bands. We also offer argon purging where necessary for the particular casting and cleanliness requirements of a shop. We have various head compositions to ensure throttling control and a clean shut-off at the end of the casting sequence, as well as a choice of designs with rigging supplied with the stopper as required.

1. Multiple designs for attaching the rigging.
2. Ceramic glaze coating to prevent external oxidation. High temperature glaze coatings are available for extreme preheat conditions.
3. Zr-based slag zone composition to ensure greater resistance to slag corrosion.
4. High quality AL-C materials having high corrosion and thermal shock resistance.
5. Porous plug to prevent steel from entering the stopper.
6. Spinel head materials having exceptional resistance to slag corrosion.
7. Mg-C head materials having good slag corrosion resistance when processing steel with Ca.
8. High quality Zr-based materials to ensure good corrosion resistance of the head.
