METHOD FOR PRODUCTION OF HIGH-TEMPERATURE CONDUCTORS Russian patent published in 1998 - IPC

FIELD: electrical engineering, in particular, methods for production of long-length metal-ceramics composite single or multiple conductors for electric equipment. SUBSTANCE: method involves deformation of metal-ceramics composite article and high-temperature processing in several stages with intermediate deformations between high-temperature processing stages which are performed on long-length conductors by means of bowl rolling using rollers which are made from flexible material, for example, polyurethane. Rollers are mounted to achieve ratio of contact region of conductor jacket and rollers surface which is parallel to rolling plane of conductors of different shape within range of 25-85, in particular, 45-50 for flat conductors; 30-80 for round conductors. Contact area of conductor jacket and surface of rollers is increased due to extended length of this region parallel to rolling plane up to 2-22 mm. EFFECT: possibility to make single and multiple conductors of various shapes with decreased by 20% losses with respect to intermediate pressing method; possibility to keep shape of conductor section during intermediate rolling stages, decreased level of half width of texture maximum down to 6 degrees. 5 cl, 4 dwg, 1 tbl
