Abstract：

The heat treatment of forged small roll blank(1.5 t ESR ingot) takes a long period,which influences production efficiency.Optimized heat treatment process design was decided by researching and analyzing the group of tests on the process of normalization,spheroidization and hydrogen annealing.The double stages of spheroidization was changed into a single stage for that the normalization was canceled,which saved operating time of 45 h and the production efficiency was almost increased by 20% based on keeping the previous properties.
