Abstract
Methods of billet casting are provided herein. The methods may include the steps of assembling a billet caster with a shroud extending from a tundish to above a mold such that the shroud does not reach molten metal in the mold, delivering molten metal from a ladle into the tundish, delivering molten metal from the tundish through the shroud to the mold, the shroud inhibiting contact between the molten metal and air, casting the molten metal into billets in the mold and cooling the billets below the mold with a coolant spray, and delivering the cooled billet to a runout table to be cut to length.
