Abstract：The microstructure of low yield tensile ratio steel requires for dual-phase which is difficult to control. Though giving full role of pre-leveler with heavy reduction and adjusting Muplic cooling parameters, plate shape is greatly improved;steel properties and yield tensile ratio are better by optimizing the tempering process and controlling the ratio of hard-soft phase. The low yield ratio of oil storage tank steel that uses online quenching+offline tempering process is below to 0.90, and the performance conformity ratio is more than 90%.
