Simulation of Curved Surface Forming of Steel Plate by Induction Heating

Abstract Ship hull is a compound curved shape and most of shipyards have been using gas heating method for thesurface forming of steel plate. This traditional forming process have problems such as difficulties in heat input controland poor working conditions due to loud noise and air contamination. Recently, researches on automatic hull formingsystem have been conducted using high frequency induction heating method which have good control ability and favorable working environment. In this study, the induction heating simulation system for curved surface forming of steel plate was developed and induction heating experiments were performed. Based on the results of this study, efficient induction heating coil design and optimal heating conditions for the automatic hull forming system can be obtained.
