ABSTRACT:
To produce tubular molded parts made of high-temperature superconductor oxide material based on bismuth, calcium, strontium and copper, a homogeneous melt of the oxide with a specified stoichiometry is allowed to run at temperatures of 900.degree. to 1100.degree. C. into a casting zone rotating about its horizontal axis. The solidified molded part is removed from the casting zone and it is annealed for 4 to 150 hours at 700.degree. to 900.degree. C. in an oxygen-containing atmosphere. A plant for producing tubular molded parts includes a rotatably arranged mold (4, 9) which is provided at least at one end face with a front plate 6 which reduces its free cross section, a runner 7 extending into the interior of the mold (4, 9) and a crucible 8 arranged above the runner 7 which is capable of feeding the runner 7 with melt (cf. FIG. 2 A).
