ABSTRACT:
A lance guiding and changing apparatus is presented for immersion lances which enables the lances to be changed or replaced at a rapid rate, the lances being held particularly firmly and rigidly during the plural injection processes. The immersion lance guiding and changing apparatus comprises, in part, lance storage means, lance transfer means, and lance changing means. The lance changing means includes a vertical mount which is capable of rotating about its vertical axis via a suitable drive means. At least two lance carriages are suspended on the mount, and the carriages are vertically transportable along the mount. The lance storage means, preferably comprised of a turret-type container capable of holding a plurality of lances, supplies or receives new and used lances respectively. The lance transfer means transfers the new or used lances between the storage means and the rotatable mount.
