Project: Research

Project Details

Description

Induction heating (IH) is used in many applications such as: surface hardening, pre-heating for forging/forming, assembly processes, metal/alloy fusion, etc. The primary attraction of this technology is that it offers relatively fast heating rates and due to its direct nature there is little loss of energy in raising the temperature of refractories or other extraneous objects. Thus, if it is applicable it represents an extremely cost effective method of heating. Moreover, advances in key technologies, i.e. power electronics, control techniques, and magnetic component design, have allowed the development of highly reliable and cost-effective systems, making this technology readily available and ubiquitous.

Although IH systems have reached certain maturity, there are still some issues to address to further increase its performance and a number of challenges, notably in its application to non-axisymmetric geometries and it controlling the temperature gradient in the workpiece.

This proposal focuses on examining the capability of commercial software to simulate this process and then developing a validated model. A proposed secondary area for research is the measurement of temperature during IH, particularly on scaled surfaces to deliver improved yield and reduced wastage.

The AFRC’s proposed approach to this project is described below in a series of individual work packages. Depending on member agreement the AFRC may seek an industrial IH supplier to partner on this project – examples might include Ajax Tocco, Inductelec (Sheffield), or Inductotherm (Cheltenham). For coil design the AFRC already has contacts with Induction Coil Solutions with whom it has worked in the past.

It is recognised that elements of this project may require the AFRC project team to liaise with colleagues in the Electrical and Electronic Engineering Department for support in carrying out measurements during trials and for possible simulation of circuit dynamics.
