    摘要: One aspect relates to a method for producing a ring electrode, including providing an outer element including an outer tube; providing a first inner element, including a first inner tube having a first core made of a sacrificial material, a material of the outer element and a material of the first inner element having a similar microstructure to each other; providing a second inner element, including a second core made of a sacrificial material; forming a composite tube by arranging the first inner element and the second inner element inside the outer element, the first inner element and the second inner element being arranged eccentrically; drawing the composite tube in a longitudinal direction of the composite tube, the material of the outer element and the material of the first inner element retaining a similar microstructure; separating a composite tube disk from the composite tube; removing the sacrificial material of the first core; and removing the sacrificial material of the second core to obtain a contacting opening in the ring electrode.

    摘要: A method of producing a clad billet includes inserting a solid carbon or low-alloy steel (CS) material into a hollow interior of the slightly larger diameter (CRA) cylinder so that a standoff gap is provided between an outer surface of the (CS) material and the inner diameter of the (CRA) cylinder; providing an explosive material around the (CRA) cylinder; detonating the explosive material to collapse at least the inner diameter of the corrosion resistant alloy cylinder onto the outer surface of the solid carbon or low-alloy steel material and eliminate the standoff gap, creating at least a partial metallurgical bond at an interface with the outer surface and resulting in a composite billet assembly; and extruding the composite billet assembly to reduce its size and form the clad billet having a metallurgical bond between the (CS) material and the (CRA) cylinder.

    摘要: The present invention relates to a method and tools for manufacturing of seamless tubular shapes, especially tubes and canisters. In the method of the invention the tubular shape is extracted from the flash (1) continuously produced during the plunging of a consumable rod (2) against a rigid anvil (3). The tools of the invention include a consumable rod (2); a non-consumable or consumable rigid anvil (3); first means for rotating the consumable rod (2) and the non-consumable or consumable rigid anvil (3) relatively with respect of each other; second means for plunging the consumable rod (2) and the non-consumable or consumable rigid anvil (3) relatively against each other; open die condition configuration for continuous production of flash (1) during said plunging.
