High-Frequency Inducting Plate Bending Forming with Gravity on Different Thickness Ship Plate


Article Preview

In this article, a FEM model of high-frequency induction bending with gravity is established and with which the heated temperature, stress, deformation, residual stress and bending angle after cooling, etc are studied on different thickness ship plate. The results show that the steel plate can be heated to 860 above the austenitic temperature. Heating temperature is gradually decreased as the thickness increase, while there is a fluctuation in the late. As the plate thickness increases, in mm, the bending angle of the plate gradually decreases, and gradually increases in 8mm14mm, and then decreases in the late. Under the given heating conditions, thin plate and the mm thick plate have the best result of deformation. The stress in heat area reaches to the yield stress of Q345, and promotes plastic deformation due to the role of heating temperature gradient and gravity. When the plate has cooled, the residual stress is mainly concentrated at the bottom of the coil.
