Abstract:
1. A furnace access apparatus, comprising: a furnace device in direct, linear communication with the interior of a metal melt furnace through a furnace aperture along a first axis; a furnace aperture plug for insertion into the furnace aperture along a second axis that is not co-axial with the first axis; and a powered furnace aperture plug reciprocator coupled to the furnace aperture plug for reciprocating the furnace aperture plug in the furnace aperture and for inserting and removing the furnace aperture plug from the furnace aperture; wherein the furnace aperture plug prevents communication between the furnace device and the interior of the metal melt furnace when the furnace aperture plug is in a closed position and allows communication between the furnace device and the interior of the metal melt furnace without moving the furnace device when the furnace aperture plug is in an open position.
