Abstract
Pour tubes for use in conjunction with slidable gate valves that regulate the flow of molten metal from the pour opening in a bottom pour teeming vessel are operatively positioned with respect to the gate valve collector nozzle by means of mounting apparatus of particular construction. A pouring tube is replaceably positioned in the apparatus which is operative to manipulate the tube within a confined space into its operating position with respect to the collector nozzle between the teeming vessel and a receiving vessel.
Claims15
Means for mounting a pour tube in operative relation to the pour opening in a bottom-pour teeming vessel comprising:
- a) a stationary base;
- b) vertically extensible and retractable mast means upstanding from said base and rotatable about its longitudinal axis;
- c) open ended journal means attached to said mast means adjacent the upper end thereof;
- d) an elongated arm received in said journal means for rotation about the longitudinal axis of said arm and for relative axial movement with respect to said journal means, said arm extending outwardly from both ends of said journal means and having means adjacent one end thereof for releasably attaching a pouring tube;
- e) means disposed on the opposite side of said journal means from said vessel and engaging the other end of said arm for selectively rotating said arm about its longitudinal axis and for moving said arm axially with respect to said journal means;
- and
- f) means for selectively adjusting the axial position of the pouring tube attaching means with respect to said base.
Means for mounting a pour tube in operative relation to the pour opening in a bottom-pour teeming vessel comprising:
- a) a stationary base disposed remote from said teeming vessel;
- b) mast means upstanding from said base having a longitudinal axis in laterally spaced relation to said pour opening, and said mast means being extensible and retractable along said longitudinal axis and rotatable thereabout;
- c) open ended journal means attached to said mast means adjacent the upper end thereof, the axis of said journal means being substantially normal to the axis of said mast means;
- d) an elongated arm coaxially disposed in said journal means for rotation about the longitudinal axis thereof and for relative axial movement with respect thereto, said arm having means adjacent one end for releasably mounting a pour tube with its axis substantially parallel to the axis of said pour opening;
- e) means for imparting compound movement to said pour tube including means for rotating said arm within said journal means and for moving said arm axially with respect thereto;
- and
- f) means for selectively adjusting the axial position of the pour tube mounting means with respect to said pour opening.
