Center segregation of continuous casting slab is the main cause to form banding structure in fine blanked steel. Dynamic soft reduction technique is an effective measure to improve the center segregation of continuous casting slab. In this paper

final solidifying end of 230 mm continuous casting slab can be accurately determined by rivet pin shooting experiment improvement of soft reduction process. The center segregation of representative fine blanked steel was beyond M2.4 of Manesman standard before improvement of soft reduction process ( at zone 9 and 10

total reduction 7. 5 mm). The result of rivet pin shooting experiment is the reference of parameter of dynamic soft reduction. With the parameter optimizing of soft reduction (at zone 8 and 9

total reduction 10 mm)

center segregation of continuous casting slab can be controled within M2. 0 of Manesman standard. Banding structure in fine blanked steel can also be controled effectively.
