Horizontally and vertically movable elevated apparatus for placing slag retaining means in tapping converters

摘要

Slag retention devices for use in a tapping converter, such as used in the steel industry, are positioned by an improved apparatus positioned substantially above the charging floor in front of the tapping converter and movable horizontally with respect to an overhead support and vertically with respect to the charging floor and the converter. A tiltable drive mechanism telescopically supports an elongated boom, the outer end portion of which is arranged to releasably carry a slag retaining device and move into the tapping converter and position the slag retaining device in the tap hole thereof.
