| Abstract: | Under the condition： superheating temperature of molten steel being 20 -30 ~C, drawing speed 1.9 m/min, second cooling unit water quantity 0.7 L/kg, mold electromagnetic stirring 4 Hz and 240 A, the process of end electromagnetic stirring is researched to reduce central carbon segregation index in billet. It is showed from the result that the index is smaller than 1.05 under 6Hz and 160A. |
