| Abstract: | Based on higher upsoundness of YS of Q345B plate,TMCP process practice of Q345B plate was proceeded with controlled cooling equipment at Lin-gang medium-plate plant.The experiment got the rigions of initial rolling temperature,temperature-delay depth and carbon equivalent of finishing for Q345B plate,thereby,the roundness of Q345B plate was increased. |
