| Abstract: | Based on Nb microalloying technology established in the traditional process, combining with process characteristics in EAF-CSP, this article has analyzed the main reason of mix-grain microstructure phenomena in Nb microalloyed steel produced in EAF-CSP through optical microscope analysis,chemical phase analysis and hot-deformation simulation test etc methods. According to these preceding studies, GISE has adjusted each producing process, and succeed in eliminating mix-grain phenomena in Nb microalloyed strip. |
