- •
A rolling method with large deformation resistance gradient is proposed.
- •
FEM is studied considering effect of oxide scale thickness and specific heat changing.
- •
Equivalent strain with large temperature gradient gradually moves to the central part of the plate.
- •
Average ferrite grain size at the center of the plate decreases and mechanical properties increase.
