Uso de finos de pella en la industria siderúrgica venezolana.

Contenido principal del artículo
Resumen
Existe una gran variedad de subproductos de la industria siderúrgica, cuando el diámetro de los mismos es menor a 100 mesh, llevan el nombre de finos. Entre los subproductos que presentan esta característica se tiene: finos de pella, escamas, finos de casas de humo, glóbulos férreos, entre otros. Estos finos están compuestos principalmente por hierro. Sin embargo, una gran proporción de ellos no están siendo utilizados, generando pérdidas económicas, al no ser usado el hierro presente en ellos, y problemas ambientales, ya que hay grandes acumulaciones de estos subproductos. El presente estado del arte, tiene como objetivo determinar posibles usos alternativos de los finos generados en la industria siderúrgica. Para ello se realizó una búsqueda bibliográfica en trabajos académicos y patentes. Se identificaron diez (10) usos alternativos de los finos de pellas y otros subproductos de la industria siderúrgica: pellas frías, pellas fundidas, briquetas para aglomerar finos, sinterizado compuesto de pellas, pellas de material reciclado, sinterizado de material reciclado, mezcla con minerales que contengan otros metales distintos al hierro, usos de finos directamente, micrometalúrgia y modificadores de escoria. Adicionalmente, se evaluó la factibilidad de aplicar alguna de estas alternativas en la industria siderúrgica venezolana.
