An aluminum wire feeder consisting of a flexible conduit and positioning tube are connected to a removable shroud by a tube holder. A feed mechanism provides a continuous source of aluminum wire for feeding the same to a continuous casting mold, only during shrouding conditions.
Claims1
In the continuous casting of steel from a bottom-pour vessel into a vertically oscillatible continuous casting mold through a removable shroud, said vessel having a pouring nozzle in its bottom wall, said shroud being movable into an active position around said nozzle and in sealable relation with said vessel, and into a stand-by position remote from said nozzle, the improvement comprising apparatus detachably connected to said shroud for feeding wire to said mold during the shrouding of the pouring stream, said apparatus comprising:
- (a) fastening means carried by and at the lower edge of said shroud for holding a wire directing tube, said fastening means consisting essentially of:
- (i) an adjustable tube clamp for adjusting the direction and the angle of inclination of said tube,
- (ii) a support ring removably connected to said shroud and carrying a protrusion adapted for engagement with said tube clamp, and
- (iii) means for holding said tube clamp in a desired orientation;
- (b) a wire detecting tube positioned in said fastening means;
- (c) a flexible conduit attached to the end of said tube remote from said mold;
- and
- (d) a wire feeding mechanism communicating with said flexible conduit for feeding wire through said conduit into said mold.
