  • Patent number: 10987728
    Abstract: Apparatus for producing elongate strands of metal comprises a rotatable wheel having a circumferential surface, at least one nozzle for directing a molten metal onto the circumferential surface and a collection means for collecting solidified strands of metal formed. The solidified strands are formed on the circumferential surface from the molten metal and are separated from the circumferential surface by centrifugal force generated by rotation of the wheel. The circumferential surface has a circumferentially extending structure having circumferentially extending edges and recesses formed between or bounded by the edges, and by an apparatus for controlling a gas pressure applied to the liquid metal which moves the liquid metal through the nozzle opening and delivers it to the circumferential surface of the rotatable wheel.

  • Patent number: 6796363
    Abstract: Disclosed herein is a cooling roll which can provide bonded a magnet having excellent magnetic properties and having excellent reliability. A melt spinning apparatus is provided with a tube 2 having a nozzle 3 at the bottom thereof, a coil 4 for heating the tube and cooling roll 5 having a circumferential surface 53 in which dimple correcting means is provided. A melt spun ribbon 8 is formed by injecting the molten alloy 6 from the nozzle 3 so as to be collided with the circumferential surface 53 of the cooling roll 5 in an inert gas atmosphere (ambient gas) such as helium gas, so that the molten alloy 6 is cooled and then solidified. In this process, dimples to be produced on a roll contact surface of the melt spun ribbon are divided by the dimple correcting means, thereby preventing formation of huge dimples.

  • Patent number: 6581674
    Abstract: Disclosed is a method and apparatus for making a molten film of metal, steel, in particular a steel film, more uniform, by strip casting, in which the molten material which is applied to a revolving belt is to have a thickness and properties which are as uniform as possible across the width of the strip. To make the strip more uniform over its width, forces are introduced into the metal film with a component which is perpendicular to the direction in which the strip is conveyed, which forces make the profile of the molten film of metal more uniform.

  • Publication number: 20030102105
    Abstract: An apparatus for producing ingots of nonferrous metals, comprising a continuous casting machine provided with a moving casting shell composed of a plurality of segments arranged in succession, each segment having a portion, with bottom and side walls, of the casting shell formed therein and being open on the sides directed toward the contiguous segments. The segments are movable along a closed path that has at least one substantially straight portion at the casting region. The segments, along the at least one portion of path, are substantially aligned and form a casting shell that is continuous and substantially straight and is closed, along at least one portion of path downstream of the casting region, by closure means at its side that is arranged opposite with respect to the bottom.

  • Patent number: 6527041
    Abstract: Methods and apparatus for forming a plurality of uniformly sized solder balls utilize a stencil having a plurality of holes of uniform volume disposed on a substrate. Solder is disposed in the holes of the stencil on the substrate. Typically, the solder is in the form of solder paste which is distributed into the holes using a squeegee. While within the holes of the stencil on the substrate, the solder is melted to form solder balls. The stencil may then be removed to leave the solder balls on the substrate, or the solder balls may be removed while the stencil remains on the substrate.

  • Patent number: 6450242
    Abstract: A method and a belt casting device for producing thin billets, in particular composed of steel, has an endless belt to which liquid metal is supplied via a feed device which has a casting channel and is connected to a metallurgical vessel. In this case, the feed device is in the form of a casting channel which has a first casting channel part in the form of a restriction channel part, and which has a second casting channel part whose opening faces the endless belt and whose size corresponds to the cross-sectional area of the finished product. The feed device is connected to a container to which liquid melt can be fed from a metallurgical vessel. Measurement elements are provided, which can be used to detect the level of the liquid melt in the container and/or the thickness of the billet located on the endless belt. Furthermore, the measured values are connected via a measurement and control element to an actuator which is connected to an element for adjusting the outlet rate from the metallurgical vessel.
