TRANSACTION PAPER
Refining of charge chrome: A study of some products and applications
C.-J. Rick

SYNOPSIS
By implementing a converter downstream of the reduction furnace it is possible to broaden the product range significantly. The converter can also successfully be used to strip furnace slag from chromium oxide. Some process alternatives and their economical, practical and environmental implications are studied using process models developed based on UHT's long experience in stainless steelmaking, stainless steel process control and charge chrome refining.
Keywords: Charge chrome, converter refining, ferrochromium products, process design
