GCr15钢的快速球化退火工艺

Fast Spheroidizing Annealing for GCr15

根据"离异共析"原理,对GCr15钢采用低温奥氏体化和快速球化退火新工艺,该工艺使得球化退火的奥氏体化保温时间和等温转变时间总和缩短到2h以内,与传统退火工艺相比节约能源50%以上。

A new technique of low austenitizing temperature and fast spheroidizing annealing technique is worked out by DET （divorced eutectoid transformation） for GCr15. The fast spheroidizing annealing technique, which reduces the conventional technology spheroidizing annealing austenitization holding and isothermal spheroidizing time in 2 h, also saved energy nearly over 50% compared to the old annealing technology.
