摘要： Manufacturing narrow-diameter hollow metal objects utilizing metals difficult to work plastically has been problematic with conventional manufacturing methods; the narrower the diameter the higher the manufacturing cost has been, and under some circumstances manufacturing has been impossible. A plurality of metal wires is worked into a twisted wire cluster, adjoining companion metal wires are brought into contact in planar contacting portions, and the cluster is made unitary by supplying an adhesive agent along the outer side, producing a hollow metal object possessing a uniform inner diameter and a clean inner surface.

摘要： A casting nozzle for supplying a molten alloy liquid of aluminum alloy or magnesium alloy to a movable mold for continuous casting from a tundish, in which the molten alloy liquid is stored. The casting nozzle is fixed to the tundish. The casting nozzle tip arranged on the movable mold side is made of a highly heat-conductive material having a heat conductivity of 0.2 W/mK or more, and a highly elastic material having an elastic modulus of 5000 MPa or more, etc. By making the tip of the casting nozzle with a material having superior thermal conductivity, the irregularity in solidification of the molten alloy liquid is decreased and thereby the surface quality of a cast alloy is improved. The nozzle tip is formed with a material having high elasticity and superior elastic deformability, whereby the interstice between the movable mold and the tip of outer peripheral edge of the nozzle is narrowed, and accordingly a cast alloy having superior surface quality can be obtained.

摘要： A casting nozzle suited to manufacture a casting material of pure magnesium or magnesium alloy is provided. A nozzle 1 is utilized to manufacture a casting material 100 by supplying molten metal to a portion between rolls 10 which become a casting die, and arranged so that a pouring port 4 is located between a pair of rolls 10 opposed to other. This nozzle 1 includes a main body 1a formed of oxide material such as alumina, and a coating layer 3 which is provided on the inner surface of the main body 1a which comes into contact the molten metal, and formed of material that does not include oxygen substantially. Since the main body 1a does not come into direct contact with the molten metal due to the coating layer 3, it is possible to prevent oxygen included in the main body 1a from reacting with the molten metal. Further, in the nozzle 1, a casting die contact portion 2 which comes into contact with the rollers 10 is formed of thermal insulation material, whereby it is prevented that the molten metal in the nozzle 1 is cooled through the casting die contact portion 2 by the rollers 10.
