An apparatus for plugging holes in an electric smelting furnace or the like is disclosed. The apparatus comprises first and second tubular members, the second being adapted to be secured to the first by means of two assemblies mounted exterior of the tubes each of which may serve as either a release or a pivotal element about which the second tubular member may be rotated to facilitate loading and/or cleaning of either tubular member. A piston is provided which travels substantially the longitudinal extent of the first tubular member to extrude, under pressure, a material suitable for plugging a hole.

Apparatus for plugging holes in an electric smelting furnace or the like

A computerized control system for receiving information concerning the operating parameters in an electrical furnace, and for controlling the feeding of corrective and additive charge to the furnace, for controlling the position of the electrodes, and for controlling the power consumed by the furnace. The system includes a discharge hopper for the selective discharge of solid materials to electric smelting furnaces. The hopper comprises a transit part and a reservoir part. Because of its physical construction, the transit part will empty before the reservoir part, but when the transit part is empty the contents of the reservoir part will follow automatically.
