| Abstract: | J55 Steel plate was developed based on the equipment and process condition in the Flexible Thin Slab Rolling Line in Benxi Iron and Steel Group Company. The characteristics of the microstructure and properties of plate produced by thin slab continuous casting and rolling line was analyzed and compositions of the steel as well as the process parameters for steel making and rolling were designed. The plated was produced and its microstructure and properties were evaluated. It was achieved to make the steel clean and improved the inclusion distribution and then enhance the mechanical properties by Nb, Ti micro-alloying combining with LF-RH refining and proper controlled cooling and rolling. |
