| Summary: | In this paper, the advantages of the longitudinal profiled(LP) steel plate is described, and the characteristics of LP plate rolling process is introduced. In contrast to the ordinary steel plate, The change rule of the bite angle and other parameters is put forward from the rolling principle. On this basis, the rolling plan is formulated. The finished condition of the steel plate is TMCP, and the size of the steel plate is corresponding to the setting value. Test result shows that the performance meets the standard of Q345. This indicates that LP plate has successfully developed in the Shougang thick plate plant.
