Title: Method and apparatus for tap hole reaming

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.
