Edge effect of load in transverse flux induction heating systems

Abstract

The problem of edge effect in continuous transfers flux inductor heaters (TFIH) is examined using a new problem oriented program based on a structure of ELTA program. This new program is designed to simulate distribution of power sources and temperature along the width and length of the workpiece in continuous TFIH system. In paper methods of calculation are described and the results of several case studies are presented. Main attention was paid to distribution of the power source and temperature along the width of thin strips from copper, aluminum, stainless steel and ferromagnetic steel.  (Full text)

Simulation of induction heat treatment of steel articles with the help of ELTA 6.0 and 2DELTA software

Abstract

Processes of induction heat treatment of steel workpieces are studied with the help of ELTA and 2DELTA software for electrothermal analysis. A novel process of combined hardening of extra heavy balanced drill pipes is studied as an example. The results of the computations are confirmed by experimental data. (Full text)

Investigation of Gear Heat Treatment by Use ELTA 7.0

Abstract

The induction contour hardening of external gear is the most effective technology to increase steel hardness. A great deal of research using 3D software has been carried out and published in this field of knowledge. In order to perform these tasks more efficiently the authors offered new version of ELTA with special Gear Application. An idea of 2D gear model and structure of ELTA is described. FDM with internal coupling of EM and thermal problems according to a Total Flux Method for external electromagnetic problem is used. ELTA can calculate integral parameters of inductor, temperature field and power sources distribution in the cross-section of gear. Investigation may be simpler and faster than in the case of 3D simulation. Several examples of induction hardening taken into account variable frequency of power source and single or double frequency process are presented.

Preliminary investigation of metal melting in ICF ELTA

Abstract

Several problems of melting in the induction crucible furnaces are described. A short description of ICF ELTA program for simulation of electromagnetic and thermal parameters in these systems is given. The program was used at the initial stage of the development of new technological processes and the induction crucible furnaces. Preliminary results allowed to find a rational decision of an induction system, the required parameters of a refractory and a power supply. Non-conductive and graphite crucibles of the furnace were compared from electrical and economical points of view.  (Full text)

Control System of Smart HF Power Supply Integrated with ELTA Program

Abstract

The control system of smart high frequency power supply for induction heating of titanium wire is presented. This system is intended for the use in the developments of FREAL&Co Ltd. A program of numerical calculation ELTA integrated in control system of the induction heating installation is described. ELTA calculates a temperature distribution in a cross-section of a cylindrical load taking into account the parameters exported from the power supply.  (Full text)
