The 1.8~6.3 mm strip of V microalloying HSLA S-F80 steel(0.03~0.07C
1. 10~1.60Mn
≤0.05Nb
≤0.05Ti
0.05~0.25V
0.010~0.035N)is produced by EAF-LF-CSP process at Zhujiang steel.The examination results showed that with recrystallization control rolling process breakdown temperature 1000~1100 ℃
finishing temperature 820~950℃ and coiling temperature 550~650℃
the structure of strip was 3~4 μm ex- tra-fine ferrite + minor pearlite
the size of precipitated phase V(C
N)was 44 nm and the yield strength of strip was 590~620 MPa.
