| Abstract: | Normalizing after forging, isethermal spheroidal annealing and dehydrogenation annealing have
been experimented and studied.The influence of preheat treatment process on the structure and network of
cold working roll as well as the influence of heating temperature and time on structure and hardness have been studied. The results show that the proper preheat treatment process should be normalizing at 950 ± 10 °C,isothermal spherical spheroidal annealing at 790± 10°C dehydrogenation annealing at 660-690°C |
