Abstract

La invencion tiene por objeto aleaciones inoculantes destinadas al tratamiento del arrabio para fundicion que contienen (en peso) de 0.005 a 3 % de un elemento del grupo bismuto, plomo y antimonio, de 0.3 a 10% de metales del grupo de las tierras raras y eventualmente aluminio hasta 5 % y calcio hasta 1.5 %, el resto es ferrosilicio, el lantano constituye mas de 90 % de los metales de las tierras raras que entran en su composicion. Las aleaciones segun la invencion permiten obtener una inoculacion eficaz de la fundicion y evitan la aparicion de microrrechupes en las piezas moldeadas.
