摘要:通过计算机数值模拟和实际工艺试验相结合的方式研究了模具钢真空热处理的加热滞后时间与エ
件特征的关系,其目的是改进目前的真空热处理加热保温时间过长的状况,在保证产品热处理质量
的前提下,尽可能地减少无效加热保温时间,节约能源。

Abstract: The relation of the delay-time during vacuum heating die steel to the workpiece characteristics was
investigated through the combination of computer simulation with practical process test in order to improve the
excessively long holding time of vacuum heat treatment cycle, i. e, to reduce the unavailable holding time to
minimum, so as to save energy under the condition able to assure heat treatment quality
Key words: vacuum heat treatment; H13 steel; computer simulation; holding time; mechanical property
