Studies On Energy Conversion Of The Model Of Prestressed Steel Wireinduction Heating System

Prestressed steel wire is widely used in industrial materials. As a key development project, we want to increase production of the high-quality steel wire strongly. Prestressed steel wire has a high elastic deformation limit, a high anti-yielding capacity and lower relaxation loss, so it belongs to the high-quality prestressed steel products. Prestressed wire products play an important role in prestressed wire products, so it is of great significance to study on the heating aspect in the stabilization treatment and ensures compliance with the process requirements in the production process and make the energy consumption at the same time.The electromagnetic induction heating has the advantages of high heating speed, high efficiency, less oxidation of the dough surface, less decarburization, and can be obtained relatively clean. These advantages make it possible to become the ideal means of stabilizing process heating of the blank. Wire stabilization process heating means uses electromagnetic induction heating in this article. The induction heating use the heat generated by the electromagnetic induction and eddy current effect within the wire to heat it. It is essential to understand the wire induction heating process, and its temperature distribution to ensure the wire quality. And it plays a very important role to understand the wire induction heating system energy consumption value under different electrical parameters for achieving lower production costs as well as energy conservation.In the premise of designing the induction heater of induction heating system, we use software to create a physical model of induction heating system in accordance with the principle of induction heating, electromagnetic effects and the finite element method of electromagnetic-thermal coupling numerical calculation. Then analyze the temperature field and the eddy current field distribution state of the wire in the induction heating process, establish the key electrical parameters that affect the temperature field distribution, and analyze the energy consumption of the system under different electrical parameters. It provides a theoretical basis for the tempering temperature automatically control of the wire stabilization treatment and the optimization of the sensor design.This paper contains following parts:1. Design the key part of the induction heating power supply system--induction heater according to the steel production process requirements and characteristics of induction heating.2. Use the relevant software to model the wire induction heating system, input material properties, mesh, load electrical parameters and solve according to the electromagnetic finite element analysis. Determine the temperature field distribution parameters-power frequency, current, density and heating time through the analysis of the results. Analyze the energy consumption of the system under the different electrical parameters and find a reasonable heating electrical parameters after the quality of wire being ensured.
