文摘

A 3D transient thermal model is developed to obtain the workpiece temperature field. The boundary condition is determined based on a multi-phase multi-zone heating method. The radiative heat flux is calculated by means of a simplified zone method. A novel method is presented to quickly and accurately solve the model.
