| Abstract: | The paper briefly introduces the composition of ultra-low carbon bainitic steel for hot rolled coiled sheet with yield strength of 550MPa and its production technology, analyzes the mechanism and mainly describes the controlled rolling and cooling technological schedule for 1780mm hot rolling mills, including the schedules of temperature and rolling, especially the optimizing process of accelerated cooling schedule after rolling. It also analyzes and studies the technological parameters, structure and performance of coiled sheet during test rolling and makes a reasonable technological schedule of controlled rolling and cooling for the steel. |
