| Abstract: | Through changing the voltage of pulse electric field to process molten carbon steel,we obtained refined grain and optimized control parameters of pulse voltage corresponding to the refined grain.The main element distribution and segregation in the molten steel during solidification were analyzed by the OPA (original position analyzer) and the effect of electric field on the main element distribution was investigated.Combining with previous achievements,the functioning mechanism of pulse electric filed was also studied. |
