Resumen

John Campbell shared his views on some of the significant aspects of simulation of fluid and inclusions dynamics during filtration operations of ductile iron melts using foam filters. These simulations indicated that the melt was to be damaged by the entrainment of double films after the filter. It was expected the damage was to adversely affect the benefits derived from filtering a percentage of the incoming inclusions. It was found that the adoption of a vertical down-sprue with a redundant volume at its base increased the damage to the melt by providing the opportunity for additional surface turbulence. This feature also increased the load of entrained inclusions that the filter had to remove, while a poor down-sprue design followed by a well resulted in filters blocking and overloaded with entrained films.
