Title: Numerical simulation of induction heating of a rod semiproduct for the process of rotary spin extrusion
Author: BEHULOVA, M., MASEK, B., MEYER, L. W.

Abstract: Technology of rotary spin extrusion is intended for manufacturing of semiproducts of hollow shafts for motor vehicles. It belongs to the advanced forming processes using which semiproducts with outstanding material properties can be produced applying a unique incremental deformation technique at controlled temperatures. In order to ensure a high efficiency of the process and to improve the conditions for plastic material flow, a system of induction heating and water spray cooling is expected to be integrated to the process chain. According to the virtual design for arrangement of heating and cooling components, the simulation model for numerical analysis of electro-magnetic and temperature fields in a rod semiproduct from the 20MoCrS4 steel was developed. Based on numerical experiments and analysis of temperature fields in heated rod semiproduct, the parameters of induction heating and consecutive surface cooling were defined.
