  • Arrangement for pouring a pourable melt made up of a copper alloy
    Patent number: 6602461
    Abstract: An arrangement for pouring a pourable melt made up of a copper alloy, which comprises a melting furnace, pivotable about a horizontal pivot axis, having a pouring tube which discharges pourable melt and through which the pourable melt can be conveyed under a shielding gas atmosphere to a filling end of a launder and can be conveyed through an outlet of the launder to a mold. The filling end of the launder is coverable by a hood that seals off the pourable melt from the atmosphere, the pouring tube engaging, with interposition of a seal arrangement, in pivotably movable fashion into the hood. As a result, the pourable melt can be transferred into the launder under a shielding gas atmosphere upon pivoting of the melting furnace and the pouring tub.

  • Use of oxygen-free copper deoxidized by boron or lithium as material for hollow sections
    Patent number: 4814235
    Abstract: In a hollow section of oxygen-free copper deoxidized with boron or lithium, which is to be pressed over a bridge tool, the percentage of the deoxidizing agent, boron or lithium, in the finished product is 0.01% to 0.05%. The electrical conductivity of the finished section is at least 95% IACS.
