| Abstract: | Transformation rule of special steels was investigated by means of electronic microscope and full automatic phase transformation tester(Formaster Digital).Meanwhile,through calculation of thermal transfer and mass transfer by computer.New heat treatment processes for steel slab,ingot,rolled and forged steel were developed.The results showed that more energy saving and productivity increasing could be obtained by improving old thermal cycle process in special steel plants.And the new processes have remarkable effect on improving quality and decreasing annealing hardness of steel. |
