| Abstract: | This paper summarizes the development conditions of thin strip casting and rolling technology at home and abroad, and explains the new metallurgy phenomena resulted from meta - rapid solidification and near net shape forming in thin strip casting and rolling process, such as negative surface segregation, total equiaxed crystal east structure and eliminating edge crack of strip, etc., on the basis of the research conclusions for weathering steel, ferritic stainless steel and TWIP/ TRIP steel with high Mn in laboratory, and points out thin strip casting and rolling technology is favorable for further improving material properties and preliminary explicates its industrial development direction. |
