Abstract
A support assembly for a pouring stream protection shroud 1 at the outlet gate of a metal pour vessel comprises an intermediate bearing ring 3 provided between a flange 2 of the protection shroud and a shroud holding ring 4 supporting said shroud at the outlet gate of the metal pour vessel. The holding ring may be provided with cooling gas channels 12, 13, and the bearing ring and holding ring are interlocked by pins 8 extending into a peripheral groove 7 formed in the holding ring and sandwiching a further intermediate bearing ring 16 therebetween. Lubricant may be supplied to the sliding surfaces through peripheral bores 6 and connecting bores 17 formed in the intermediate bearing rings.
Claims10
An assembly for supporting a pouring stream protection shroud at the outlet gate of a metal pour vessel, which assembly comprises:
- a shroud holding ring (4) supporting said shroud (1) at the outlet gate of the metal pour vessel and adapted to be connected to a shroud supporting fork, and an intermediate bearing ring (3) disposed between the protection shroud and the shroud holding ring, said intermediate bearing ring forming a planar sliding surface (5) with said shroud holding ring to enable free rotational motion of the protection shroud with respect to the holding ring and to thereby avoid any rotation of the protection shroud with respect to the outlet gate, the intermediate bearing ring and the shroud holding ring including means (6) for supplying lubricant to said planar sliding surface.
An assembly for supporting a pouring stream protection shroud at the outlet gate of a metal pour vessel, which assembly comprises:
- a shroud holding ring (4) supporting said shroud (1) at the outlet gate of the metal pour vessel and adapted to be connected to a shroud supporting fork, and an intermediate bearing ring (3) disposed between the protection shroud and the shroud holding ring, wherein the shroud holding ring and the intermediate bearing ring comprise an interlocking unit, the intermediate bearing ring being slidably attached to the holding ring by interlocking means, said interlocking means comprising an outer peripheral flange (11) on the intermediate bearing ring, a peripheral groove (7) formed in an outer surface of the holding ring, and a plurality of pin means (8) extending from the flange into the groove.
An assembly for supporting a ladle protection shroud cooperable with a movable plate of a rotary slide gate mechanism of a metal pour vessel for protecting the pouring of molten metal into a mould, comprising:
- a flange (2) extending outwardly from a ladle protection shroud (1), a shroud holding ring (4), an intermediate bearing ring (3) disposed between the flange and the holding ring and configured to define a planar annular sliding surface (5) with the holding ring to enable free rotational motion of the shroud and bearing ring about the holding ring and interlocking means for slidably coupling the bearing ring to the holding ring and for preventing relative axial motion between said rings.
