Blank Shape Sensitivity on Temperature Distribution of Hot Stamping Boron Steel through Conduction Heating

摘要：

　　The conduction heating overcomes shortage of the radiation heating because of rapid heating and high energy efficiency.It is mainly used for heating of components with a favorable length/diameter ratio, such as pipes, rods, wire and bands.In this study, a conduction heating system was developed in terms of Joules Law.Sensitivity of blank shapes on temperature distribution of hot stamping boron steel during conduction heating was investigated.Heating experiments of ultra-high strength steel blanks with irregular-shapes, such as ladder, joist and rectangle with variable cross-section were implemented on the system.The results showed that the final temperature field was decided by the shape of the blanks.It was indicated that the final temperature of the tested blanks was inversely proportion to the sectional area.
