Abstract: A casting mold made of a copper material having a casting surface (2) that faces a metal melt, at least one expansion joint (3) being situated in the casting surface (2); the expansion joint (3) having a width (B) that is so small that, during the casting process, no metal melt penetrates into the expansion joint (3).

Abstract: A liquid-cooled permanent chill mold for the continuous casting of metals, including a permanent chill mold plate (2) made of copper or a copper alloy and an adapter plate (3), on which the permanent chill mold plates (2) are fastened via fastening bolts (12). The permanent chill mold plates (3) are coupled to the adapter plates (3) via sheet metal holders (19) situated in their top regions and base regions (20, 21), in addition to via the fastening bolts (12).

Abstract: A method for producing a carbon nanotube-, fullerene- and/or graphene-containing coating on a substrate includes the steps of applying carbon nanotubes, fullerenes and/or graphenes onto a tin-containing coating and introducing carbon nanotubes, fullerenes and/or graphenes into the coating by mechanical and/or thermal treatment. A coated substrate produced by this method and the use of the coated substrate as an electromechanical component or lead frame are also described.

Abstract: The invention relates to a method for the production of castings made of a copper alloy comprising silicon, nickel, chromium, and zirconium, and also inter-metal primary phases, wherein an ingot is drawn by means of hot forming in only one direction at a ratio of at least 4:1, wherein a casting surface of a casting produced from the drawn ingot, said surface coming into contact with a metal melt, is substantially selected perpendicular to the drawing direction of the ingot. A casting produced in this manner is characterized by high wear resistance and increased service life, particularly when used as a block of a side bank of a double strip casting system.

Abstract: An age-hardening copper alloy made of—as expressed in each case in weight %—0.4% to a maximum of 2% cobalt which is partially replaceable by nickel, 0.1% through 0.5% beryllium, optionally 0.03% through 0.5% zirconium, 0.005% through 0.1% magnesium and possibly a maximum of 0.15% of at least one element from the group including niobium, manganese, tantalum, vanadium, titanium, chromium, cerium and hafnium. The remainder is copper inclusive of production-conditioned impurities and usual processing additives. This copper alloy is used as the material for producing casting molds, in particular for the sleeves of continuous casting rolls as components of a two-roll casting installation.

Abstract: A liquid-cooled permanent mold for the continuous casting of metals, comprising mold plates (1) made of copper or a copper alloy, which are connected respectively to an adapter plate or a water-cooling tank by clamping bolts, the clamping bolts being fastened to plateau pedestals (3) that protrude in an insular fashion from the coolant side (2), which at least partially extend into a coolant gap formed between the mold plate (1) and the adapter plate or the cooling-water tank, and have a streamlined form adjusted to the flow direction of the coolant. The coolant side (2) has cooling ribs (4, 5, 6, 7) that extend into the coolant gap and are situated from place to place between two adjacent plateau pedestals (3).

Abstract: A permanent chill mold for the continuous casting of metal, having a mold cavity (2) which has a pouring slot (3), an exit opening (4) and a casting cone (6). At least one concave bulging (7) is provided that extends in the casting direction (G), which begins at a distance (A) below a predetermined casting bath level position (5) and extends up to the exit opening (4).
