    • A ladle lining installation embodying a relatively deep cupshaped ladle and also a collapsible pattern adapted for use in the ladle and having novel facilities for centering the same in the ladle and thereafter leveling it, together with facilities whereby it may be shrunk or collapsed after the refractory lining has been completed within the continuous arcuate space surrounding the pattern in order to break the bond between it and the lining material and thereby permit the used pattern to be readily hoisted from the lined ladle. Novel means are provided for confining the rammed refractory material in such continuous arcuate space and thus preventing it from flowing inwardly over the bottom wall of the ladle.
