Abstract Abstract: By contrasting of settled and unsettled test specimens, the following conclusions were obtained: the sample imposed electric pulse in a liquid state can made the 3-D carbon segregation remarkable improved. Fluctuations of the carbon content in different cross-section were less than 4.6% for settled test specimen, but for unsettled test specimen it reached to 11.9%. The distribution of carbon content in different height sections for corresponding points--center point, 1/2 radius and edge point tend to be even if the sample was treated by electric pulse, and the variations are 4.5% and 12.5% respectively for treated and untreated sample by electric pulse.
