<p>A twin-roll caster casts steel strand of thickness preferably 5 to 35 mm. Preferably both a primary (e.g. 30 tons) and secondary tundish (e.g. 5 tons) are provided above the caster. An inert or reducing gaseous atmosphere is provided above the surface of the molten steel pool formed above the kissing point of the twin rolls. An elongated rectangular guiding shroud (4) extends downwardly from the exit port of the secondary tundish, and a transversely extending splash guard (5) extends generally horizontally outwardly from the guiding shroud (4) at the underside of the secondary tundish. The guiding shroud (4) and the splash guard (5) may also be used with a single tundish, and may be used in association with other types of caster.</p> |
