Two schemes of thermomechanical processing of F420W cold-resistant steel to produce sheets with thickness of 5 and 15 mm for manufacture of wind turbine towers, were developed and tested in laboratory conditions. The first scheme simulated hot rolling on a continuous mill, including reductions with minimal inter-deformation pauses and subsequent slow cooling. The second one corresponded to hot rolling on a reverse mill with accelerated cooling. Mechanical properties were analyzed taking into account the related structural features. Technological recommendations for hot rolling of a thin sheet made of high-strength cold-resistant steel were proposed.
