- Abstract
- Through the control of temperature and cooling system Optimization,and the pearlite spheroidization forms in the cold drawn steel bearing steel after annealing and the performance of the workpiece improves to facilitate subsequent processing. The resolution measures have been implemented for Poor microstructure and decarburization after annealing to improve production efficiency.
- Keywords
- spheroidizing microstructure; decarburization layer; once spheroidizing qualified rate
