摘要： A casting system and method for producing a metal casting is provided. The metal casting can comprise a fine-grain, homogeneous microstructure that is essentially oxide- and sulfide-free, segregation defect free, and essentially free of voids caused by air entrapped during solidification of the metal from a liquidus state to a solid state. The casting system can comprise an electroslag refining system; a nucleated casting system; and a cooling system that cools the metal casting so as to cool a liquidus portion of the metal casting. The metal casting is cooled in a manner sufficient to provide a microstructure that comprises a fine-grain, homogeneous microstructure that is essentially oxide- and sulfide-free, segregation defect free, and essentially free of voids caused by air entrapped during solidification from a liquidus state to a solid state.

摘要： A consumable electrode feed system for a refining system provides consumable electrodes to a refining system. The consumable electrode feed system comprises a side feed device that feeds consumable electrodes to a refining system in a first direction; a refining feed device that feeds consumable electrodes to a refining system in a second direction, in which the second direction being generally orthogonal to the first direction; and a connection system for connecting fed consumable electrodes to each other. The consumable electrode feed system allows for a predetermined amount of a consumable electrode to be refined in the refining system, and can position another consumable electrode above a previously fed consumable electrode. The connecting system then can connect a fed consumable electrode to a previously fed consumable electrode thus avoiding refining operation.

摘要： In a method and apparatus for the electroslag refining of metal, the method includes providing a refining vessel to contain an electroslag refining layer floating on a layer of molten refined metal. The refining vessel representing an upper part of a cooled mould comprises a plurality of superimposed sleeves which are electrically insulated from one another. The top sleeve, being the refining vessel, is substantially a non-consumable electrode and has a current lead electrically insulated from the sleeve. The molten electroslag layer is heated by a refining current which is passed from a power source through the mould and slag layer to the metal pool. An unrefined metal is lowered into the vessel into contact with the molten electroslag layer such that its surface is melted and overheated at the point of contact with the slag such that droplets of the metal are formed and these droplets pass down through the slag and are collected in a pool of molten refined metal beneath the slag.

摘要： A method for controlling electromagnetic flux concentration in a discharge guide tube for a metal refining apparatus is provided. The discharge guide tube comprises a base plate, an extension, a central orifice that extends through the extension from a source of liquid metal to an outlet in the discharge guide tube for directing a stream of metal therethrough, and an interior discharge guide tube flux concentration configuration; an induction heater system that generates an electromagnetic field in the discharge guide tube, the induction heater system being disposed on the extension with a gap defined therebetween, the induction heater system and the discharge guide tube being capable of relative vertical movement and subsequent positions with respect to each other with the gap being essentially constant. The method for providing electromagnetic flux concentration comprises providing current to the induction heater system; generating an electromagnetic field resulting from the step of providing current; and directing an electromagnetic flux to the central orifice at locations defined by the interior discharge guide tube. The step of generating an electromagnetic flux also generates heat and the step of generating heat provides a control of the flow of the stream of metal in its liquidus condition. The electromagnetic field is applied at a substantially constant level regardless of the relative vertical movement and subsequent positions between the induction heater system and the discharge guide tube.

摘要： A system and method of electroslag refining of metal is taught. The system and method includes the introduction of unrefined metal into an electroslag refining process in which the unrefined metal is first melted at the upper surface of the refining slag. The molten metal is refined as it passes through the molten slag. The refined metal is collected in a cold hearth apparatus having a skull of refined metal formed on the surface of the cold hearth for protecting the cold hearth from the leaching action of the refined molten metal. A cold finger bottom pour spout is formed at the bottom of the cold hearth to permit dispensing of molten refined metal from the cold hearth. The dimensions of the cold finger apparatus pour spout are controlled by positioning a retaining means around the outer surface of the pour spout thereby controlling the flow rate of molten metal through the cold finger apparatus.

摘要： A casting system with auxiliary cooling onto a liquidus portion of the casting can produce a metal casting that comprises a fine-grain, homogeneous microstructure. The microstructure is essentially oxide- and sulfide-free, segregation defect free, and essentially free of voids caused by air entrapped during solidification of the metal from a liquidus state to a solid state.

摘要： A bottom pour electroslag refining system refines raw material into refined liquid metal. The bottom pour electroslag refining system comprises an electroslag refining crucible; a slag; a bottom pour structure that comprises an orifice from which refined liquid metal from the electroslag refining crucible can flow as a stream of refined liquid metal; and a current path. The current path is defined in the bottom pour electroslag refining system for applying current to the raw material for melting and refining the raw material. The melted and refined raw material forms a refined liquid metal pool in the electroslag refining crucible. The current that is applied by the current path is sufficient to provide the refined liquid metal in the refined liquid metal pool with a viscosity under which the refined liquid metal can flow through the orifice under its own viscosity.

摘要： A method for the recycling of overspray powder during spray forming is provided. The method involves providing a refining vessel to contain an electroslag refining layer floating on a layer of molten refined metal. An ingot of unrefined metal is lowered into the vessel into contact with the molten electroslag layer. A current is passed through the slag layer to the ingot to cause surface melting at the interface between the ingot and the electroslag layer. As the ingot is surface melted at its point of contact with the slag, droplets of the unrefined metal are formed and these droplets pass down through the slag and are collected in a body of molten refined metal beneath the slag. The refined metal is held within a cold hearth. At the bottom of the cold hearth, a cold finger orifice permits the withdrawal of refined metal from the cold hearth apparatus. The refined metal passes from the cold finger orifice as a stream. The stream is atomized for spray forming into a preform article on a spray collection station having a solid receiving surface for receiving the atomized metal thereon to form the preform article. The powder produced during the atomization which was not deposited on the solid receiving surface of the spray collection station is recycled onto the top of the molten slag in the electroslag refining station.
