| Abstract: | Spherical annealing structure of 45 steel used for cold-rolled screw，compared with nomalizing，can improve the rolling performance，the rolling quality and the roller’s service life．Tests show：in order to obtain good spherical structure of 45 steel，the heating-speed，austenitizing temperature，holding time，cooling-speed etc，are main factors affecting the spheroidizing treatment quality． |
| |
| Keywords: | steel isothermal spheroidizing annealing cold rolled screw quality |
