Abstract: An industrial metallurgical delining assembly for dislodging and removing refractory or other material from upwardly open metallurgical process vessels. The assembly includes a spider-leg frame, the feet of which are supported on the upper periphery of the vessel, and supports a turntable over the top of the vessel. An extensible and articulatory boom depends from the turntable and selectively carries working tools at its free end for dislodging and removing material from the vessel. The vertical spacing between the uppermost end of the vessel and the turntable is sufficient to provide clearance for the boom to remove such dislodged material to a location outwardly from the vessel.

Abstract: A pouring ladle is mounted on a carriage which is movable along a track by a motor drive coupled thereto through an overrunning clutch. Movement of the carriage along the track is interrupted at a predetermined position to align the tap hole of the ladle with a rotating reaming tool. The reaming tool is axially advanced into the tap hole for reaming and then retracted and the carriage is released for continued movement along the track. The reaming tool is a hollow tubular body having a longitudinal relief slot penetrating the side thereof and an annularly shaped reaming head is concentrically and removably secured to the forward end of the body and air is fed forward under pressure into the rearward hollow end of the body for cooling and clearing of reamed cuttings.
