PURPOSE:To continuously manufacture a wire material having high critical temperatures and high stability of superconductive characteristic by continuously extruding a kneaded material of a composite oxide superconductive material powder and a binder to a long size compact and conducting binder removal treatment, covering the periphery of the compact, and continuously sintering the powder with heating. CONSTITUTION:A composite oxide superconductive material powder is obtained with individual oxide of a composition element of a sintered body or a mixture of carbonate or a mixture of the oxide and the mixture of carbonate baked and ground. A long size compact 14 is manufactured with paste, in which a raw material powder is blended together with a binder, extruded and using a molding method. The compact 14 drawn from a coiler 15 is continuously charged in a binder remover 12 of a continuously sintering furnace. The compact 14 drawn is heated at a binder removal zone 12, and a solvent and the binder in the compact 14 is eliminated. A sheet 17 is guided to the periphery of a tape-state sintered body 14 so as to envelope the body 14 at a continuously coating device 16, is welded with a laser welder 20, and thereby a complex 21 of the body 14 and the sheet 17 is formed. The body 14 is sintered at a sintering zone 13, and continuously wound to a drum 22. |
