HEATING TEST CONTROL APPARATUS, AND HEATING TEST CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a heating test control apparatus that can accurately and uniformly raise the temperature of a test object having a metallic external cylinder along a prescribed test temperature curve and then keep it at a prescribed temperature over a prescribed period.SOLUTION: A power feed circuit 3b at a heating step generates a first feed current having a first feed frequency selected mainly from a low frequency range of 1 kHz or below and uniformly raises the temperature of a laminated electrode body 12 within a metallic external cylinder 11. At a high temperature keeping step, a second feed current having a second feed frequency selected from a high frequency range of 5 kHz to 100 kHz is generated, and heats the surface layer part of the metallic external cylinder 11. Further, the power feed circuit 3b obtains a wattage (Ic×&Dgr;T) corresponding to the required calorific value supply by intermittently outputting a feed current while keeping the feed frequency constant.
