Blank Shape Sensitivity on Temperature Distribution of Hot Stamping Boron Steel through Conduction Heating
Abstract:
The conduction heating overcomes shortage of the radiation heating because of rapid heating and high energy efficiency. It is suitable for heating of blanks with an appropriate length/width ratio. In this study, a conduction heating system was developed in terms of Joule’s Law. Sensitivity of blank shapes on temperature distribution of hot stamping boron steel during conduction heating was investigated. Heating experiments of boron 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 steady temperature was decided by the shape of the blanks. It was indicated that the steady temperature of the tested blanks was inversely proportion to the sectional area.
