Abstract: For the problem of long tubular shape coefficient in the current heat treatment standard, a standard sample library consisting of 21 simulated temperature curves with Ø20-Ø40 mm diameter of the rod was established by using the Heat Transfer analysis module provided by ABAQUS simulation software and by uniform adopting environmental radiation heat transfer. Using simulation and data analysis technology, the “thickness comparison method under equivalent circular rod diameter condition” is proposed. The results show that the short tube shape coefficient is 2, and the long tube shape coefficient is 2+2Rinside/Routside.
