Abstract
A pivot is mounted to extend parallel to a spout axis. A pair of arms are mounted at first ends thereof to swivel about the pivot and carry at second ends thereof holders which support pouring pipes. Each arm can be swiveled to a position beneath the spout and precisely centered with the spout by abutment devices. The holder and pouring pipe are then raised until the pouring pipe engages the spout.
Claims18
A device for replacing pouring pipes on the spout of a metallurgical vessel, particularly a spout in an intermediate container of a continuous casting installation and closable by a slide closure, the pouring pipe being coupled in an operative position to the bottom of the spout, said device comprising:
- a pivot adapted to be mounted parallel to the longitudinal axis of a spout;
- at least two swivel arms pivotally mounted at first ends thereof one above the other about said pivot;
- each said arm having at a second end thereof a pouring pipe holder adapted to receive therein a pouring pipe;
- said arms being alternately pivotable about said pivot to an operative position such that the respective pouring pipe is centered and aligned beneath the spout;
- abutment means associated with each said arm for limiting the amount of pivoting motion thereof to the said respective operative position thereof;
- and
- means, operatively associated with said arms, for displacing the respective said holder and pouring pipe held thereby in a direction coaxial with said spout axis to selectively engage the said pouring pipe against said spout and to release such engagement.
