The result shows that the inclusion, high cooling speed and uneven of cooling speed after rolling are the main reasons for steel plate cold bending rupture.
Taking into account the rolling load is uneven, to balance electrical loads and reduce the electrical capacity slowdown in the increase between a flywheel and electric motors.
考虑到轧制负荷很不均匀，为了均衡电机负荷，减少电机的容量，在减速机和电动机之间加有飞轮。

Small deformation in high temperature is easy to cause incomplete recrystallization and bulky and uneven grain. It is hard to eliminate them in subsequent rolling process.
