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.

摘要： A method for atomizing a titanium-based material to particulates in a controlled atmosphere. In the method, titanium is skull melted in a crucible. The molten titanium-based material is transferred to a heated tundish. The molten titanium-based material may be stabilized in the heated tundish and then formed into a free-falling stream. The free-falling stream of the molten titanium-based material is impinged with an inert gas jet to atomize the molten titanium-based material. The method also includes cooling the atomized titanium-based material, and collecting the cooled atomized titanium-based material.

摘要： An improved method for making a metal powder employs improved apparatus comprising, in combination, a fluid-cooled hearth for receiving metallic material which defines an alloy and which is to be melted, a plasma heat source adapted to melt the metallic material, a powder metal producer, and means to introduce the molten metallic material from the hearth into the powder metal producer. The fluid-cooled walls of the hearth resolidify a portion of the molten metallic material to form a skull as a barrier between the hearth and additional molten alloy produced within the hearth. This method and apparatus restricts introduction of impurities into the molten alloy which is later introduced into the powder metal producer. In one form, a fluid-cooled pouring trough, as a stream control device, can be disposed between the hearth and the powder producer to receive molten metal from the hearth and to introduce it into the powder metal producer.

摘要： A method of atomization of refined metal is taught. The method starts with 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 in the form of droplets is refined as it passes through the molten slag. The refined metal droplets are collected in a cold hearth apparatus having a skull of refined metal formed on the surface of the cold hearth and 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 rate of flow of molten metal through the cold finger apparatus is controlled principally by controlling the rate of melting of the unrefined metal. The metal flowing from the cold finger apparatus is introduced to the upper end of a ceramic melt guide tube. Liquid metal emerging from the lower end of the melt guide tube is atomized by a gas orifice closely coupled to the lower end of the melt guide tube.

摘要： Apparatus for producing a metal powder includes a cooled hearth structure in which a metallic alloy is melted and a heat source above the hearth positioned to heat the melt in the hearth. The cooling of the hearth causes a protective hearth skull to form between the melt and the hearth itself. The hearth is placed within an environmental control chamber. A supply structure provides a continuous supply of the metallic alloy to the hearth structure from the exterior of the chamber. A metal powder producer is positioned to receive molten metal from the hearth, and a continuous stream of the molten alloy from the hearth is transferred to the metal powder producer. The transfer is accomplished by tipping the hearth or by teeming through an opening in the bottom of the hearth. The hearth structure can utilize two individual hearths, controllably arranged so that molten metal is drawn from one hearth while the other is recharged.

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： 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.
