Abstract：

The wind power tower plays an important role in the economic evaluation of wind turbine. Therefore, in order to study the rolling process of the integrally formed longitudinal rib plate, the simulation calculation was conducted by finite element method, and the influence laws of various factors such as rolling process parameters and hole-type parameters on the height of rib were analyzed. Then, rolling experiments of small-sized longitudinal rib plate were carried out, and a batch of longitudinal rib plates with the rib height greater than 2 mm, the base plate thickness of 3 mm, the width of 200 mm and the length of 700 mm were obtained. The research shows that increasing the reduction rate under certain conditions is an effective way to increase the height of rib, too high heating temperature and too long holding time will increase the burning loss, and the increased iron oxide scale will reduce the friction factor, which is not conducive to biting and rib formation. The experimental results are in good agreement with the finite element simulation results, which can provide a theoretical basis for the application of tower with ribs.
