The paper is devoted to the optimal inductor design for surface hardening of steel cylindrical billets. The heating stage of surface induction hardening is considered as an object with distributed parameters, which unknowns are design characteristics of the induction installation. In real industrial conditions the main technological parameters are often defined by the intervals of their possible values. That is why, in the paper the optimal design problem under the conditions of interval uncertainty of initial billets temperature and thermal exchange coefficient is formulated. Solution of the formulated problem is carried out by alternance method of parametric optimization based on numerical model developed in Altair FLUX software.
