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.
Claims20
A method of billet casting comprising the steps of:
- a. assembling a billet caster with a shroud, the shroud comprising an upper portion and a lower portion wherein the upper portion forms a nozzle, and wherein the shroud extends from a tundish to above a meniscus of molten metal in a mold such that the shroud does not contact the molten metal in the mold;
- b. delivering the molten metal from a ladle and into the tundish;
- c. delivering the molten metal from the tundish through the shroud and to the mold wherein the shroud extends from the tundish to above the meniscus of molten metal in the mold, the shroud inhibiting contact between the molten metal and air;
- d. casting the molten metal into billets in the mold and cooling the billets below the mold with a coolant spray to form cooled billets;
- e. delivering the cooled billets to a runout table to be cut to length.
