摘要： A method and apparatus is disclosed for casting a composite ingot made of metals that are susceptible to surface oxide formation when molten. The method involves co-casting at least two metal layers from at least two molten metal pools formed within a direct chill casting apparatus. During the casting operation, movement of metal oxide formed on the upper surface of at least one of the pools towards an edge of the pool is restrained by an oxide skimmer positioned close to an edge of the pool above an external surface or metal-metal interface of the ingot. The apparatus provides a DC caster with at least one oxide skimmer that operates in this manner.

摘要： The present invention relates to a ladle block for use in a bottom of a molten metal ladle. The ladle block reduces the amount of contaminants, particularly slag, exiting the ladle during casting operations. The ladle block includes a floor defining an outlet and sidewalls substantially orthogonal to the floor. The floor and sidewalls define a channel having dimensions of length, width and height. Channel dimensions are determined from the Froude number, which is based at least partially on the casting flow rate.

摘要： The present invention relates to a metallurgical ladle and more particularly to the bottom of the ladle having an outlet through which the molten metal can drain. An object of the present invention is to increase the efficiency of a ladle draining operation, including reducing the amount of discarded metal, avoiding the premature flow of slag through the outlet, and reducing the contamination of slag in the molten metal effluent. The ladle bottom comprises a plurality of terraces and flow channels, ultimately directing the stream of molten metal to an outlet of the ladle. The terraces are described as capturing slag and the channels permit molten metal to flow preferentially through the outlet.

摘要： A method and apparatus is provided for temporarily retaining slag and nonmetallic particles in a tundish while molten metal is being transferred through the tundish to other desired vessels. In particular, a meltable dam is placed into an opening between the chambers in a tundish, and the meltable dam retains an accumulation of molten metal in the pour chamber of the tundish with the slag and nonmetallic particles floating on top of that level such that the slag and nonmetallic particles are above the opening between the chambers of the tundish. The dam then completely melts and allows the transfer of molten metal through the opening. The slag and nonmetallic particles are retained in the pour chamber, however, because the molten metal being transferred into the pour chamber maintains the level in that chamber above the opening until almost all of the metal has been transferred into and through the chamber. In this manner, problems associated with the transfer of slag and nonmetallic particles with the first flow of molten metal in VIM teeming operations are eliminated.

摘要： The present invention provides a new and improved method and apparatus for tapping molten metal through the tap hole of a metallurgical vessel. The apparatus utilizes a ladle or a BOF furnace or other metallurgical vessel used for the containment of molten metal. At least one extension drive mechanism is attached to the support structure to position the distal end of a lance within the vessel a predetermined distance above the surface of its contents. The lance is connected to an inert gas source such as Argon. Once the lance is properly positioned, the inert gas is directed onto the surface of the molten metal to prevent the slag from entering the tap hole. An alignment drive can also be attached to the support structure to adjust the position of the extension drive relative to the vessel so that the lance may be properly positioned within the vessel above the tap hole. The extension and alignment drives are operatively controlled by a computerized controller which interfaces with the sensors to monitor the physical characteristics of the vessel. The controller operatively controls the drives to position the lance a predetermined distance above the tap hole of the vessel.

摘要： A metallurgical ladle, and more particularly the bottom of the ladle or a ladle block in the bottom of the ladle, have an outlet through which the molten metal can drain. The ladle bottom contains an open-end channel bounded by at least one wall with a major dimension perpendicular to a line joining the center of the outlet entrance to the center of the wall. In selected configurations, opposing faces of the walls bounding the open-end channel are convex in the horizontal plane and concave in the horizontal plane, respectively.

摘要： A system and a metering assembly are both disclosed, and both relate to reducing the vortexing which can occur during the outflow of molten metal from a holding reservoir to a mold during casting operations. The system includes a first molten metal holding and pouring box with first predetermined dimensions, a second molten metal holding and pouring box with second predetermined dimensions which are less than said first predetermined dimensions and which is positioned relative to said first molten metal holding and pouring box to receive a flow of molten metal therefrom, a first flow control device for controlling the outflow of molten metal located at the bottom region of the first molten metal holding and pouring box, an antivortexing insert located in an inlet portion of said first flow control device for controlling the outflow of molten metal and in direct contact with the molten metal in said holding and pouring box. The antivortexing insert has at least one opening and at least one vane for interacting with the molten metal as it flows into the inlet portion of the first flow control device to reduce vortexing. In its broadest aspect, the present invention is directed to antivortexing insert for a metal pouring vessel including an outlet orifice having a central opening therein for the passage of molten metal therethrough. The antivortexing insert comprises at least one vane extending across the central opening for interacting with molten metal flowing therethrough. The antivortexing insert is located at an inlet region of the central opening.
