Apparatus for changing protective shrouding tubes on casting vessels used in continuous casting

Abstract From the Canadian patent

A continuous casting apparatus comprising a casting vessel having a closable pouring opening for pouring metal through a protective tube into a flow-through vessel arranged beneath the pouring opening and into which vessel the outlet end of the protective tube extends, and means for changing the protective tube.
