Billet Process and Equipment
Understanding Key Factors to Improve Billet Surface Quality and Casting Mold Life
Jean-Philippe Dubé -- Aluiminerie de Bécancour Inc., Canada ;
Billet producers often use molds with graphite technology where an oil/gas mixture is injected through a graphite ring to improve billet quality. A new measuring device assesses critical factors affecting billet quality and casting mold longevity, particularly graphite rings. Analysis identifies critical factors of oil type, graphite porosity and uniformity required to produce ideal billet surface quality, while increasing mold longevity.
