The crankshaft for 4-stroke marine diesel engine is produced by TR forging providing a continuous grain flow. The preform of crankshaft is a round bar with a ring groove. Partial flame heating and forging are performed sequentially in TR forging process for a large crankshaft. The axial length of the preform is shortened as TR forging is progressing. In this study, the effect of axial length change of the preform on the axial temperature distribution in the heated part was investigated during TR forging process. Theoretical approach with the assumption of the preform having a cooling fin was performed to obtain the steady state temperature distribution of the preform along the axial direction. The validity of theoretical approach was verified by comparing heat transfer analysis results with FEM analysis results. Based on this study, it was found that the effect of axial length change of preform on the axial temperature distribution in the heated part would be negligible in case of constant temperature inside furnace.
