The Relationship

Purpose The purpose of this paper is obtaining the optimal parameters of induction heating and melting systems by use of the new programs ELectro-Thermal Analysis (ELTA) 8.0 and Induction Crucible Furnace (ICF) to improve a quality of final products. Design/methodology/approach Simulation of continuous through heating prior a drawing through the draw plate is realized by an optimization procedure. Additional application of ELTA 8.0 “Heating of Wire” reveals the relationship between power, time and thermal profile of load during heating. Rational variants of ICFs for melting processes are obtained using several step-by-step iterations. Findings ELTA 8.0 program permits to optimize the continuous heating of copper, steel, titanium and other wires. ICF ELTA program was used at the initial stage of the development of new technological processes and the ICFs. This program provides a preliminary evaluation of an induction melting process and system before the use of more sophisticated 2D or 3D programs. Results of optimization 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. Originality/value Fast calculation of ELTA programs allows the designer to provide the required temperature distribution in a cross section and along the part to control the real-time processes of heating and melting.

ABSTRACTThe melting of Fe3Al-based alloys at the Oak Ridge National Laboratory (ORNL) and commercial vendors is described. The melting processes evaluated include arc melting, air-induction melting (AIM), vacuum-induction melting (VIM), vacuum-arc remelting (VAR), and electroslag remelting (ESR). The quality of the ingots studied are based on internal soundness and the surface finish obtained. The ingots were analyzed for impurity levels observed in the alloys by various melting processes. Recommendations are made for viable processes for commercial melting of these alloys.
