Abstract: A device for transporting a medium includes at least one channel which extends in an axial direction and through which the medium is guided. The channel is enclosed by an electrically conductive inner envelope that is connected to a first potential equalization conductor. An electrically conductive outer envelope is provided between the channel and an electrically conductive outer casing and is connected to an electrically conductive second potential equalization conductor. Arranged between the channel and the outer envelope is an electrically insulating intermediate layer which is produced from heat-insulating material.

Abstract: A copper alloy for use as material for a casting mold or a casting mold component selected from the group consisting of mold plate, mold tube, casting wheel, casting drum, casting roller, and melting crucible. The copper alloy includes, in percent by weight (proportion by mass of the melt analysis in %): silver (Ag) 0.020-0.50, zirconium (Zr) 0.050-0.50, phosphorus (P) not more than 0.060, chromium (Cr) not more than 0.005, balance copper (Cu) and other alloying elements including unavoidable impurities, with a proportion of the other alloying elements being less than or equal to (?) 0.50.

Abstract: A method and a device for flexibly rolling a metal band by guiding the metal band through a roll gap formed between a first working roll and a second working roll, and by varying the size of the roll gap in such a way that band sections with a greater band thickness and band sections with a lesser band thickness are obtained over the length of the metal band. In the device and method, the time of contact between each point on the circumference of the first working roll and the metal band is shorter in duration than the time of contact between each point on the circumference of the second working roll and the metal band such that an asymmetric band thickness profile is obtained in a region of the band sections with a lesser band thickness.
