COMPOSITE SUBSTANCE PROCESSING METHOD FOR CERAMIC SUPERCONDUCTOR

摘要

PURPOSE:To perform uniform-thickness rolling by rolling a ceramic-metal group composite substance via a pair of rolling rolls under a preset condition. CONSTITUTION:During rolling, lubricant 22 is applied to the face and the back of a composite substance 21 which is delivered between a pair of rolling rollers 11, 12 and a supersonic vibrator 13 is driven during a rolling process while giving a rolling portion 14 supersonic vibration. Then, after machining, the composite substance 21 is heat treated to obtain a ceramic superconductor with uniform property in its longitudinal direction. The lubricant 22 with the coefficient of kinematic viscosity being 200cst or more at room temperature is used. As a result, the composite substance including ceramic in metal can be rolled in uniform thickness and a good-property ceramic superconductor can be obtained.
