    摘要： The invention relates to a method for producing a superconductive element to be used as a wire-in-channel superconductor in magnetic resonance imaging (MRI) and in nuclear magnetic resonance (NMR) applications, which superconductive element contains a superconductive wire and a copper component having a longitudinal groove and the superconductive wire being positioned in the groove. In order to produce the wire-in-channel superconductive element by a mechanical contact between the superconductive wire and a wall of the groove in the copper component, at least one contact surface is coated with a lead free solder material before having the mechanical contact. In order to enhance the thermal and electrical conduction and to create a bond between the said components the soldering material is fused in annealing process step.

    摘要： Apparatus for continuous vertical casting of metal strips, comprising: a mould (10) having top and bottom ends an open-ended mould cavity (C), a tundish (11) having a discharge opening (11A) in direct communication with the mould cavity (C) to feed molten metal into a mould entrance opening (E) past an interface between the tundish (11) and the mould (10); a sealing device (14) forming a seal at said tundish-mould interface to prevent molten metal from entering said interface, and a device (12) for supplying molten metal to the tundish (11) and maintaining a level of molten metal therein. The sealing device (14) comprises a pair of flat horizontal surfaces (10A, 11B), one on the mould around the entrance opening (E) and one on the tundish (10) around the discharge opening (11A), and a sealing element (14A) formed of a sheet of graphite and being in constant sealing engagement with both said surfaces (10A, 11B).

    摘要： The invention relates to an apparatus for rolling a metallic product comprising a mill frame (18), a first cantilever roll shaft (19), a second cantilever roll shaft (20), both said roll shafts (19, 20) being mounted on the mill frame (18) with two sets of bearing assemblies (38, 39, 40, 41), a first roll-ing ring (21) mounted on the first roll shaft (19), a second rolling ring (22) mounted on the second roll shaft (20) said rolling rings (21, 22) forming a nip (23) in between, at least one ring (29) arranged with its inside surface (43) in rolling contact with the first roll shaft (19) and with at least one intermediate roll (27), which intermediate roll (27) is ar-ranged also in rolling contact with the second roll shaft (20) and at least one drive end (42) arranged at the end of either roll shafts (19, 20) for driving the mill (16). The in-vention also relates to a method of producing a metallic product.
