Abstract: An apparatus for preparing a tube end for rod drawing with a floating mandrel has a releasable holder for the tube end centered on an axis, a frustoconical and spreadable floating mandrel, and a device for inserting the mandrel into the tube end and spreading the mandrel to flare the tube end. The apparatus further has a feed mechanism for inserting the floating mandrel into the tube end and/or a deforming device for making at least one indentation in the tube for holding the floating mandrel.

Abstract: A method for material testing of an elongated work piece drawn through a drawing die arrangement, wherein the drawing die arrangement includes a drawing tool that acts on the elongated work piece, forming it in a forming region, carries out the material testing in the forming region.

Abstract: In a method for the production of semi-finished copper products, first copper is melted and cast to produce copper anodes, in one casting procedure, within multiple ingot molds, subsequently copper cathodes are formed by electrolysis, using at least one of the copper anodes, and then these copper cathodes are processed further to produce semi-finished copper products. A long-term coating is applied to at least one of the ingot molds as a wash, a sulfur-free wash is applied to the ingot mold and/or part of the work pieces cast in the ingot molds is directly processed further to produce semi-finished copper products. A method and an apparatus applies a wash to an ingot mold and a system produces semi-finished copper products.

Abstract: A device for rolling of pipe blanks has a planetary cross-rolling mill, an advancing bed, a pipe blank feed, a pipe blank advancing unit that pushes the pipe blanks through the planetary cross-rolling mill, proceeding from the advancing bed, the unit having at least one advancing apparatus, and having a mandrel rod and a mandrel rod holder. The pipe blank feed has an axial pipe blank conveying unit that conveys a pipe blank axially into a readiness position, which is provided axially behind the mandrel rod holder. The advancing apparatus is disposed between the planetary cross-rolling mill and the mandrel rod holder, and has a slide.

Abstract: A single carriage of the drawing apparatus for pulling a continuous metal workpiece through a drawing die is displaceable back and forth by a linear electronic motor drive. A coil forms a supply upstream of the die which can pay off a length of the workpiece to form a loop adapted to be drawn through the die without tensioning it against the coil.

Abstract: A roll shaft assembly especially for a planetary cross roll rolling mill for tubing and the like has the roll shaft and mill roll connected by a conical centering arrangement and a screw, preferably coaxial therewith with the torque transfer being effected by tooth rings on the ends of the shaft and roll and having interdigitating teeth.

Abstract: In the planetary skew rolling blooms to form seamless metal tubing or pipe the internal tool is retracted at the leading and/or trailing end of the tubular bloom to allow the rolls to seal the end or ends and prevent coolant from entering the rolled tubing or bloom. The internal tool is advanced back into its normal rolling position after the end has passed the rolling location.

Abstract: An apparatus for drawing a strand has a frame extending in a longitudinal direction, a pair of substantially identical linear motors each having a primary fixed on the frame, and a movable secondary slidable along the respective primary in the direction. The primaries extend parallel to the direction and are transversely spaced on a plane extending in the direction. A strand clamp capable of gripping the strand is fixed between the secondaries. Electricity is supplied to the primaries to longitudinally displace the secondaries and clamp in the frame so that the clamp and any strand held by it are advanced longitudinally through the frame.
