Abstract
The invention provides a remotely controlled furnace tap hole tapping system. The system is pneumatically driven and is able to tap holes placed at different heights, different positions, and different angles. The invention replaces an oxygen filled lance which is consumable, with a solid metal lance. The lance is carried by a carrier system, which moves long a track. The invention provides a gantry that is able to move the carrier system to different tracks. The pneumatic drive system cools the tapping system, in addition to driving the tapping system.
