secondary cooling water flow rate (0. 83 -1.8 L/kg) and final electromagnetic stirring (0 - 400 A
6 Hz) on phosphorus segregation in cross section of 130 mm x 130 mm casting of steel 82B (/% : 0. 79 〜0. 81C
0. 21 ~0. 24Si
0. 81 〜0. 83Mn
0.012 -0.016P
0. 005 ~Q. 008S
0. 25 〜 0. 30Cr) has been studied. The results show that the maximum segregation of phosphorus in billet is at the juncture of column crystal and equiaxial crystal but not at solidification center; with increasing secondary cooling water flow rate
decreasing casting speed and increasing intensity of final electromagnetic stirring
the maximum phosphorus segregation ratio decreases obviously-
