Title:
BATCH TYPE RAPID HEAT TREATMENT METHOD O METAL STRIP
Document Type and Number:
Japanese Patent JP2002226913
Kind Code:
A
Abstract:
To increase heating-cooling speed without modifying any heat treatment facility and reducing the difference in heat history by the winding position of a work by improving the heat transfer of the heat treatment dominated by the heat conductivity of the work.
A strip of the work is wound in an overlapping manner with a metal strip of heat conductivity larger than that of the work, and subjected to the heat treatment.
