Provided are a method and apparatus for refining titanium scraps and sponge titanium, which can remove oxygen from a melt by supplying a deoxidizing gas to the surface of the melt in order to refine titanium scraps and sponge titanium. The method for refining titanium scraps and sponge titanium comprises supplying hydrogen ions and electrons in plasma to a titanium melt to remove oxygen from the titanium melt surface having an oxide layer formed thereon. In addition, the apparatus comprises: a vacuum chamber; a crucible located in the vacuum chamber and configured to perform melting by the magnetic field of an induction coil in a state in which a melt and the inner wall of the crucible; a calcium gas supply means configured to supply calcium gas from the bottom of the crucible to the space between the inner wall of the crucible and the melt.

The present patent refers to a process for the recycling and recovery of waste, particularly that of plastified and aluminized packaging, cartoned or not, by means of a method and equipment for extracting and separating the main components present in them for the recovery of waste, avoiding environmental pollution, recycling of waste constituents, and recovery of constituents: Plastic, aluminum and paper in their original form, with the steps A, B, C, D, E, F, G, H, I, J, L, M, O, P, Q e R, bringing advantages of obtaining reusable grade polymer; obtaining isolated aluminum; to make use of a low cost and low energy consuming solvent; to allow the pulp cellulose to be recycled in the production of paperboard for boxes, to be incorporated as part of a mechanical pulp load or even to be incorporated to the bleaching process; to have lower processing and investment costs and to have a lower cost/benefit ratio.

A tapping system for removing molten fluid from a vessel, the tapping system includes: a taphole assembly configured to receive molten fluid from a vessel; an induction coil encircling at least a portion of a taphole channel in the taphole assembly; a launder assembly configured to receive fluid exiting the taphole channel and to form a pressure seal; and a plasma torch extending into the vessel and configured to direct a plasma plume toward an inlet of the taphole channel.

A method for reducing molten raw materials, includes placing the raw materials, in a solid or molten state, on an inductively heated bed with coke pieces. The reduced melt that runs off the coke bed is collected and the waste gases are discharged. A coke bed is inwardly limited by a tube-shaped element through which the reaction gases are drawn off via a plurality of draw-off openings in the tube-shaped element. The corresponding device has a reactor for a bed with coke pieces and an induction heater with at least one induction coil. The reactor has a loading opening and a discharge opening for the treated melt. The coke bed is ring-shaped around a tube-shaped element. The material of the tube-shaped element allows inductive coupling to the induction field of the induction coil and it has draw-off openings for drawing off reaction gases from the coke bed.
