Abstract: In a method of preparing an oxide superconducting wire comprising the steps of filling up raw material powder for an oxide superconductor in a metal sheath and rolling the same in this state, frictional force on surfaces of rolls employed for rolling is increased in the rolling step in order to improve denseness of the raw material powder, thereby improving the critical current density of the oxide superconducting wire. In order to increase the frictional force, films having large frictional force are formed on the roll surfaces, a coating material is applied to the roll surfaces during rolling, or the roll surfaces are roughened, for example.

Abstract: A process and apparatus for continuously transforming a flat metal strip into an elongated pipe, in which the strip is fed through a forming tool along a curved forming path wherein the longitudinal edge portions are progressively turned up into cross-sectionally arcuate portions leaving between a substantially cross-sectionally rectilinear section, the width of which progressively decreases during travel of the strip through the forming tool. The curved forming path in the tool is such that it has a radius of curvature R(z) in its longitudinal direction, the arcuate portions each having a radius r.sub.o and the decreasing width of said rectilinear section being 2x(z) (wherein z is the distance of travel through the tool). The radius of curvature R(z) is controlled in sole dependence on r.sub.o and the differential quotient x'(z). In the resulting elongated tube, relative differences in travel distance between arbitrary areas in a transverse cross-section of the strip forming the pipe are substantially completely eliminated without plastic deformation in the longitudinal direction.

Abstract: A CORE-FORMING WIRE, TO BE COVERED WITH METAL, IS CONTINUOUSLY DRAWN FIRST THROUGH A CIRCUMFERENTIAL MILLING DEVICE FOR SKIN REMOVAL AND THEN THROUGH AN AXIALLY OPERATING SHAVING AND PROTECTIVE DIE TO PROVIDE A VIRGIN SURFACE. FROM THE SHAVING DIE IT MOVES IN UNCONTAMINATED CONDITION INTO A BATH FOR APPLYING A METAL COVER OR SHEATH TO ITS SURFACE BY ELECTROPLATING, HOT-DIPPING, TINNING OR THE LIKE. THE CORE IS IN COVERED CONDITION AFTER LEAVING THE BATH AND AFTER SOLIDIFICATION OF THE SHEATHING MATERIAL IS PASSED THROUGH SUITABLE FINISHING MEANS. THE ELECTROPLATING, HOT-DIPPING OR TINNING OF CONTINUOUS LENGTHS OF CORE-FORMING METAL FOR FORMING A DIFFERENT METALLIC COATING OR SHEATH THEREON REQUIRES THAT THE CORE SURFACES BE VERY CLEAN. THIS IS PARTICULARLY TRUE IN THE CASE OF ALUMINUM WIRE REQUIRED TO BE ELECTROPLATED WITH COPPER, FOR ALUMINUM IS EXTREMELEY PRONE TO RAPID REOXIDATION IN AIR AFTER OXIDE REMOVAL. SUCH OXIDE ACTS AS A CONTAMINANT INTERFERING WITH APPLICATION OF A STAISFACTORY METAL COVERING. THUS THE INVENTION IS PARTICULARLY USEFUL FOR IMPROVEDLY ELECTROPLATING A COPPER SHEATH ON AN ALUMINUM CORE WIRE BUT IT IS ALSO USEFUL FOR OTHER COMBINATIONS OF CORE AND COVERING METALS EMPLOYING HOT-DIPPING, TINNING OR THE LIKE.
