| Abstract: | Based on the characteristics of thin slab casting and rolling technology(TSCR),this paper systematically studied the precipitation regularity of V element during the continuous casting,the soaking,the rolling,and cooling crafts,as well as the influence of the micro-alloy precipitation on the distortion austenite re-crystallization and the ferrite transformation during the production in TSCR.Using V micro-alloying technology and adopting the corresponding production control craft, the plate with 550 MPa yield strength successfully was developed.The micro-alloying high strength plate has the outstanding toughness,the cold forming performance and the good welding performance,which completely satisfied with automobile,semi-trailer and engineering requirements while formed and welded. |
| Keywords: | thin slab casting and rolling micro-alloying high strength plate |
