Title:
VACUUM HEAT TREATMENT DEVICE FOR FOIL BASE MATERIALS AND HEAT TREATMENT METHOD FOR FOIL BASE MATERIALS
Document Type and Number:
WIPO Patent Application WO/2021/106439
Kind Code:
A1
Abstract:
The present invention provides: a vacuum heat treatment device for foil base materials, said device being capable of continuously performing a heat treatment on a base material that is formed of a metal foil with high treatment accuracy; and a heat treatment method for foil base materials. A vacuum heat treatment device (1) according to the present invention is provided with: a vacuum chamber; an unwinding shaft (12); a winding shaft (46); at least a pair of front and back heating mechanisms (22); and at least a pair of first cooling mechanisms (23) that are arranged in front and at the back of a base material. A foil base material (W) is carried along a treatment path from the unwinding shaft (12) to the winding shaft (46) in the vacuum chamber. The heating mechanisms (22) are arranged so as to respectively face the front surface and the back surface of the foil base material (W) in the treatment path of the foil base material (W), and heat the foil base material (W). The first cooling mechanisms (23) are arranged so as to respectively face the front surface and the back surface of the foil base material (W) at a position that is closer to the winding shaft (46) than the heating mechanisms (22) in the treatment path, and cool the foil base material (W).
