For a steel pipe with upset, heat treatment will be required to improve mechanical properties such as high tensile strength, fracture toughness and so on. When a pipe with upset is heated by induction heating, predetermined target preheating temperature distribution is very effective to get uniform heat treatment temperature. However, it is not so easy to get the target temperature distribution. Since induction heating has electro-magnetic edge effect at pipe end and selection of preheating position is difficult due to many discrete positions. To get the target temperature distribution, optimal control procedures using finite element method, regression analysis and non-linear programming are presented. It is found that the procedures are effective to achieve the target temperature distribution. Since estimate by FEM using preheating conditions obtained by the procedures can almost agree with the target preheating temperature distribution.
