The present invention relates to a new and improved construction of apparatus for exchanging pouring tubes at a casting vessel of the type having a closeable bottom pour discharge nozzle or opening during the continuous casting of metals, especially steel, wherein a vertical pouring tube which protrudes into an open-ended vessel is equipped with guide means which provide for such pouring tube a path of movement out of an approximately horizontal infeed or introduction position into a substantially vertical casting position. During the continuous casting of metals tubular-shaped protective devices are used both between the casting ladle and the tundish as well as also between the tundish and the continuous casting mold in order to protect the casting or teeming jet against oxidation. Such tubular-shaped protective devices enclose the teeming jet either over its entire length or over a part of its length and will be referred to hereinafter as pouring tubes.
Provides uniform pour rate and helps prevent floating surface dross and contaminents from entering the mold cavities. Cast iron bowls; handles remain cool. Our most popular ladle for zinc alloys.
The present invention relates generally to the continuous casting of steel and to the special ceramic components which are employed therein. More particularly, the invention concerns a ceramic pouring tube, commonly referred to as a ladle shroud, which permits the transfer of molten metal from a ladle to a casting tundish located beneath the ladle. Molten metal is then directed from the tundish into a continuous casting mold or molds positioned beneath the tundish, all in a well-known manner.

A metal casting installation comprises a ladle comprising an inner nozzle in fluid communication with the through-opening of a top gate plate. The installation contains a ladle shroud coupling assembly comprising a support frame comprising a bottom gate plate and a passage. The support frame is slidingly coupled to a planar bottom surface of a top gate plate of the inner nozzle of the ladle, such that the opening of the bottom gate plate can be brought in or out of registry with the through-opening of the top gate plate.
Continuous castingalso called strand castingis the process whereby molten metal is solidified into a "semifinished" billetbloomor slab for subsequent rolling in the finishing mills. Prior to the introduction of continuous casting in the s, steel was poured into stationary molds to form ingots. Since then, "continuous casting" has evolved to achieve improved yield, quality, productivity and cost efficiency.
