    Abstract: In a device for atomizing and granulating liquid oxidic slags such as, e.g., converter slags, blast furnace slags or waste incineration slags, including a slag tundish having an outlet opening into which a height-adjustable lance for a propellant jet opens and to which a cooling chamber is connected, the outlet opening is surrounded by an immersion tube arranged concentrically therewith while forming an annular gap. A guide body capable of being adjusted in the axial direction of the lance is arranged in the region of the nozzle mouth of the propellant jet lance, which guide body deflects the propellant jet in the radial direction.

    Abstract: Methods for controlling the superheat of the stream of molten metal from an electroslag refining apparatus is taught. The methods include the introduction of unrefined metal into an electroslag refining process apparatus 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 or exit orifice is formed at the bottom of the cold hearth to permit dispensing of molten refined metal from the cold hearth. The super heat of the molten metal flowing through the exit orifice of the cold finger apparatus is controlled, preferably utilizing a processor, such as a computer, by coordinating the rate of induction heat supplied to the metal within the cold finger apparatus and the rate of heat removal from the metal within the cold finger apparatus through the cold finger apparatus itself thereby providing metal having a specific superheat exiting the exit orifice.

    Abstract: A method of electroslag refining of 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 if 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 by controlling the rate of melting of the unrefined metal; by controlling the hydrostatic head of molten metal and salt above the bottom pour cold finger orifice; by controlling the rate of induction heat supplied to the metal within the cold finger apparatus; by controlling the rate of heat removal from the metal within the cold finger apparatus through the cold finger apparatus itself and through adjacent gas cooling means; and by applying force to slow down and/or interrupt the flow of metal through the cold finger apparatus.

    Abstract: Titanium is induction melted to produce a molten mass thereof and a water-cooled crucible having a nonoxidizing atmosphere and a bottom opening. The current to the coil used for induction melting is adjusted to produce a levitation effect on the molten mass in the crucible to prevent the molten mass from flowing out of the bottom opening. The molten mass is also maintained out-of-contact with the crucible by providing a solidified layer of titanium between the molten mass and the crucible. After production of the molten mass of titanium, the current to the induction coil is reduced to reduce the levitation effect and allow the molten mass to flow out of the bottom opening of the crucible as a free-falling stream of molten titanium. This stream is struck with an inert gas jet to atomize molten titanium to form spherical particles. Spherical particles are cooled to solidify them and are then collected. The free-falling stream from the crucible may be directed to a tundish from which the molten mass flows through a nozzle for atomization. The titanium may be melted to form the molten mass outside the crucible with a molten mass then being introduced to the crucible.

    Abstract: A molten metal spray-depositing apparatus employs an ejection nozzle for receiving a molten metal stream and having a configuration for confining and imparting mechanically an angular momentum thereto which produces stream break-up into a metal particle spray when the stream becomes unconfined upon exiting the nozzle. There are stationary and rotating versions of the ejection nozzle. The stationary ejection nozzle has a flow channel with internal angular elements, such as spiral grooves, which engage the moving molten metal stream to impart angular momentum thereto as it passes through the channel. The rotating ejection nozzle may have internal elements within the flow channel, such as notches or serrations, which engage the moving molten stream and cause it to rotate with the nozzle as it passes through the channel. The two nozzles can also be combined to impart the angular momentum and accomplish melt stream break-up.
