| Abstract: | High strength steel ZJ700MC with yield strength grade of 700 MPa was successfully developed by using Ti-microalloyed technology in the EAF-CSP line at Zhujiang Steel.The composition design,smelting process,continuous casting and rolling process of the steel,as well as the mechanical properties of the hot-rolled product are introduced in the paper.An analysis to the strengthening mechanism of the high strength steel shows that the enhanced strength and toughness of the steel were caused by the refinement of ... |
