- Casting macine description and design
- Sequences - Cast up to 10 heats on a tundish.
- Tundish shape and volume - Delta shape tundish with three nozzles. Fourth stand blocked off.
- Steel flow control devices from ladle and tundish to mould -Ceramic pouring tube connected to slide gate nozzle which conveys steel from ladle to tundish. Argon gas shrouding in pouring tube to prevent re-oxidation. Baffle in tundish with holes to define pour box. Basic tundish flux used on top of liquid steel. Rice hulls added for Insulation. Submerged entry nozzles (SEN) are placed in the tundish from the inside of the tundish and are rammed with NOXITE in place. Dry-vibe is added and then baked in place.
