Abstract
An apparatus which is adapted to move along a tundish, ladle, or the like having a generally closed lower end, enclosed sides, and an open upper end. The apparatus sprays the sides and lower end of the tundish with refractory material. The apparatus comprises a nozzle having an inlet and an outlet, and a base movable in an x direction generally horizontally along the tundish, a boom movable in a vertical y direction, a lance movable in a z direction generally perpendicular to the x and y directions, and a rotatably swivel bracket for rotating the nozzle outlet about an axis extending in the y direction. The apparatus also includes piping for supplying fluidized refractory material to the nozzle inlet, and a water ring for wetting the fluidized material before the nozzle outlet.
Claims10
A gunning apparatus which is adapted to move along the inside of a tundish or ladle having a generally closed lower end, enclosed sides, and an open other end, and which sprays the sides and lower end thereof with refractory gunning material, said apparatus comprising a base,
- an upright support beam attached to said base,
- means for moving said base horizontally along the tundish parallel to one of said sides,
- a horizontal boom extending generally perpendicularly to the direction of travel of said base and extending over the open upper end of the tundish,
- a cradle slidably mounted on said support beam and slidably supporting said boom,
- means for moving said boom horizontally relative to said cradle perpendicular to the direction of travel of said base,
- means for moving said cradle vertically relative to said support beam,
- a lance attached to said boom and perpendicular thereto, which extends generally into the tundish, and which has a lower end,
- a nozzle having an inlet and an outlet,
- means for rotatably mounting said nozzle on said lance lower end so that said nozzle outlet is generally perpendicular to said lance,
- means for rotatably moving said nozzle relative to said lance,
- means for supplying fluidized refractory material to said nozzle inlet,
- means for wetting the fluidized material before said nozzle outlet, and
- means for supplying water to said wetting means.
A gunning apparatus which is adapted to move along the inside of a tundish or ladle having a generally closed lower end, enclosed sides, and an open upper end, and which sprays the sides and lower end thereof with refractory gunning material, said apparatus comprising
- a nozzle having a material inlet, an air inlet, and an outlet supplied by said material inlet and said air inlet,
- means for supporting said nozzle inside the tundish,
- x means for moving said nozzle support in an x direction generally horizontally along the tundish parallel to one of said sides,
- y means for moving said nozzle support in a vertical y direction,
- z means for moving said nozzle support in a z direction generally perpendicular to said x and y directions,
- w means for rotating said nozzle outlet about an axis extending in said y direction,
- means for supplying fluidized refractory material to said nozzle material inlet,
- means for wetting the fluidized material before said nozzle outlet,
- means for supplying water to said wetting means, and
- means for supplying air to said nozzle air inlet to assist in propelling the wetted refractory material against the tundish.
