Abstract

Hoisting mechanism for an oxygen lance includes a counterweighted lance carriage driven by a hoist system made up of a motor driven traction drum, guide sheaves and cables. The weight of the counterweight offsets the weight of the carriage, lance, hose complex attached to the lance, and skull build-up on the lance. In normal operation, the counterweight is elevated as carriage is lowered by the hoist system to insert the lance into an oxygen converter and conversely the counterweight is lowered when the carriage is raised by the hoist system to withdraw the lance from the converter. In the event there is a power failure which impairs operation of the hoist system, the counterweight descends by gravity causing the carriage and lance to travel upwardly upon freeing the traction drum from restraint normally applied during the blowing operation of the converter.
