ABSTRACT:
A shrouding sleeve for removable insertion between a tundish and an underlying mold to vertically enshroud a liquid stream issuing from the tundish to the mold wherein the shrouding sleeve consists of upper and lower substantially rigid sleeve portions. The upper sleeve is removably secured to the underside of the tundish and the lower sleeve is removably insertable for vertical alignment between the upper sleeve and the underlying mold. An annular flange is annularly secured to the bottom of the upper sleeve, and in a similar manner, annular flanges are also secured to the top and bottom of the lower sleeve. Another annular flange is also secured to the top of the underlying mold. At least one of these annular flanges is under continuous bias in the vertical direction so that when the lower shrouding sleeve is transversely inserted into vertical alignment between the upper sleeve and the mold, all of the annular flanges engage adjacent mating flanges to form a continuous shrouding sleeve under seal. The peripheral edges of the flanges may be annularly beveled to permit initial guided sliding lead-in engagement of adjacent engaging flanges under compression.
