Abstract
Un método para producir fierros fundidos que tienen cierta morfología deseada de cristales de grafito y que contienen modificadores y/o inoculantes de la forma de grafito, de acuerdo con el cual: a) una cantidad de muestra de fierro fundido se toma del lote de fierro fundido; b) se determina la tension superficial de la muestra; c) se compara la tension superficial de la muestra con las tensiones superficiales de los lotes de fierro fundido que se conocen por solidificarse en formas diferentes de fierros fundidos; y finalmente d) si la tension superficial de la muestra de desvía de la tension superficial que se conoce por solidificarse como la forma deseada de fierro fundido en más de un valor predeterminado, corregir las concentraciones de modificadores y/o inoculantes de la forma de grafito en una forma conocida.
