The temperature field numerical value of steel strand induction heating was calculated by using finite element analysis method. The result shows that the current density and frequency are the main electrical parameters affecting the induction heating result. By changing the current density and frequency, a large number of induction heating temperature field numerical values were calculated. The mathematical models of steel strand induction heating result were found by the regression analysis of temperature field numerical values. As a new algorithm, Genetic algorithm can solve multi-objective optimization problem. Compared with other methods, the method is very universal, high accuracy and more scientific. Based on the established mathematical models, the electrical parameters were optimized by using multi-o 『bjective genetic algorithms, the optimal solution was solved. The optimal solution has provided a theoretical basis for controlling the induction heater temperature.
