FEM modeling of a continuous induction heating process of steel wire hardening
نویسندگان
چکیده
Hardening of steel wires requires heating the wires above their Curie temperature, temperature at which the material becomes nonmagnetic causing a sudden change in the load. This change affects to the induction heating converters and is difficult to be evaluated due to the complexity of the problem and the interdependence of the parameters. In this paper a continuous Post-Curie wire heating model using commercial FEM software is presented and evaluated for two cases.

Microstructure Integrated Modeling of Multiscan Laser Forming
Laser forming of steel is a hot forming process with high heating and cooling rate, during which strain hardening, dynamic recrystallization, and phase transformation take place. Numerical models considering strain rate and temperature effects only usually give unsatisfactory results when applied to multiscan laser forming operations. This is mainly due to the inadequate constitutive models emp...

متن کاملLawd – Laser Assisted Wire Drawing
In conventional wire drawing the diameter of a wire or rod-like workpiece is reduced by drawing it through a conical die. Dieless drawing of a wire or a rod is realized by a localized heating of the work piece. As heat source for example an induction coil can be used. Immediately after having passed the heating zone the work piece is cooled to restrict the heat input on very small region. By ap...

In this paper, several control techniques for induction metal treating are examined to assess their performances using resonant series inverter. In fact, many types of steel are treated with heat to increase toughness and resistance to wear. Induction heating seems to be appropriate and provides several advantages in comparison with conventional techniques. In this paper, these techniques are e...
