NUMERICAL MODELLING OF ELECTRIC ARCS
Thermal plasmas generated by electric arc discharges
between various types of electrodes or by plasmatrons
have many well-established - and numerous potential
- applications in extractive metallurgy, materials
processing and high temperature chemistry. The current
range is from below 100 A in welding arcs to above
100 kA in electric arc furnaces (EAF) for steel-making
and submerged arc furnaces (SAF) for production of
silicon alloys. AC as well as DC is used. To improve
process understanding and equipment design a number of
simulation models have been developed reaching higher
levels of sophistication as more computer capacity has
become available. This report reviews the state-of-the
-art of arc simulation and discusses some important
problems and challenges for future modelling work - in
particular on high currents and AC operation. The
perspective is the metallurgical and chemical
engineers' demand for practical simulation models
- not the physicist's very stringent approach.
