Long bulk Bi,Pb(2223) bars of 0.4 mm thickness, without silver sheath were produced by a rolling process with rolls heated at >800°C. A newly developed rolling machine allowed the precise control of the deformation of Bi(2223) bars with no limitation in length. Already reacted Bi,Pb(2223) samples, which can not be deformed at room temperature, could be deformed at 824°C without cracking. The resulting bars reached a density of 5.5 g/cm³. Microstructural observations and X-ray diffraction measurements were performed, showing strong texture in the deformed bars. A critical current density of 1800 A/cm² was measured for samples deformed at 824°C. This process opens a new possibility in view of the fabrication of long(>1m) bars for high current leads.
