Study on Transverse Uniformity of Phase Transformation for Hot-Rolled Strip on Run-out-Table

A numerical simulation of phase transformation for hot-rolled strip on run-out-table are introduced in the present work combined with experiment. Continuous-cooling-transformation (CCT) diagram are used to regress the transformation model of Q345B. Temperature field coupled with phase transformation is analyzed on run-out-table. Evolution of temperature and organization during cooling are analyzed for the hot-rolled strip between the last stand of finishing mill and coiling. It is concluded that the transverse temperature has significant effect on the uniformity of phase transformation.
