Direct Heating Billet within Die during Hot Forging Process

Article Preview

Abstract:

This paper reports a simple and effective method to increase heating efficiency and decrease heating time that renders direct heating billet within die using resistance heating system during hot forging process. The apparatus employs resistance equipment set into the forging die, and the billet was directly resistance heating by the forging die. Base on the approach, the die as a forming condition on direct heating and forging was also researched. The result of experiments shows that the billet could be heated quickly to 1000°C in about 5 seconds and the high strength material (AISI4140) was successfully formed to the shape of bolt head. With this mechanism, the rapidly heating and isothermal deformation during the hot forging process can be achieved.
