Abstract：
In view of the problem that a steel plant in north China encountered many internal cracks in the production of Q235 B section 180×675 mm^2, the finite element method was used to carry out the simulation calculation of secondary cooling water distribution in ANSYS software. Compared with the actual situation, the existing problems of secondary cooling water distribution were found out, and corresponding solutions were proposed. It has been proved that the number of defects such as billets drum and corner crack has been reduced by 60% after adopting the adjustment scheme, and to achieve remarkable results.
