Abstract
A nosepiece for directing a charge into a crucible of a furnace. The nosepiece comprises a completely enclosed sleeve which more accurately directs the charge into the crucible. The sleeve has a distal portion that deflects the charge toward a center area of the crucible, thereby minimizing impact of the charge on the top edge of the crucible and its refractory liner. In addition, the nosepiece is split so that the distal portion is movable, thereby to provide access to an interior of the nosepiece. As a result, any bridging in the charge may be addressed by moving the distal portion to an open position.
