An industrial experiment of developing 590MPa grade dual-phase hot strip steel using laminar cooling + ultra-fast cooling technology on Baotou CSP line was introduced in the present work.The 4~11mm thickness test dual-phase steel with C-Mn raw material was produced by using thin-slab continuous casting,continuous rolling,laminar cooling and ultra-fast cooling process.The microstructures of the test dual-phase steel are ferrite + martensite.The volume fraction of martensite is 8%~12%,the tensile strength is 590~620MPa,the yield strength is 385~455MPa,the total elongation is 30%~35%.The wheel disk of heave-duty truck with the good formability was made of the test dual-phase steel.
