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.
