Abstract

La presente tiene por objeto una mezcla inoculante para el tratamiento de la fundición líquida constituida, para 5 a 75% en peso, de al menos una aleación de tipo A a base de ferrosilicio tal como Si/Fe>2, que contiene de 0,005 a 3% en peso de tierras raras, de 0,005 a 3% de bismuto, plomo y/o antimonio, y menos de 3% de calcio, con una relación (Bi+Pb+Sb)/TR incluida entre 0,9 y 2,2, y para 25 a 95%, por al menos una aleación de tipo B a base de silicio, o de ferrosilicio tal como Si/Fe>2, que contiene calcio con una cantidad tal como para que la cantidad total de calcio de la mezcla esté incluida entre 0,3 a 3%. Las mezclas según la presente presentan una buena estabilidad granulométrica en el tiempo y garantizan una inoculación eficaz de las piezas de fundición, particularmente de las piezas de poco espesor.
