Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA LA PRODUCCION DE FUNDICION DE MOLDEADO DE GRAFITO ESFEROIDAL O VERMICULAR A PARTIR DE UNA FUNDICION DE BASE. CONSTA DEL TRATAMIENTO TARDIO DE DICHA FUNDICION DE BASE, POR MEDIO DE UN ADITIVO UNICO, ACTIVO COMO NODULIZANTE E INOCULANTE, QUE TIENE LA COMPOSICION SIGUIENTE, EXPRESADA EN PROCENTAJES EN PESO: SI, 41-65; MG, 2-30; BI, 0,1-4; TIERRAS RARAS, 0,5-4; CA, BA, SR, <4 (POR CADA ELEMENTO); AL, <1,5; FE, EL RESTO. EL TRATAMIENTO TARDIO DE LA FUNDICION DE BASE SE EFECTUA POR INTRODUCCION DEL ADITIVO DESMENUZADO EN EL MECHERO DE COLADA DE LA FUNDICION, A LA ENTRADA DEL MOLDE, O POR LA TECNICA CONOCIDA COMO "EN MOLDE".THE INVENTION IS RELATED TO A PROCEDURE FOR THE PRODUCTION OF SPHEROIDAL OR VERMICULAR GRAPHITE MOLDING FOUNDRY FROM A BASE FOUNDRY. CONSISTS OF THE LATE TREATMENT OF SUCH BASE FOUNDRY, THROUGH A SINGLE ADDITIVE, ACTIVE AS NODULIZING AND INOCULATING, WHICH HAS THE FOLLOWING COMPOSITION, EXPRESSED IN PROCESSES IN WEIGHT: YES, 41-65; MG, 2-30; BI, 0.1-4; RARE EARTHS, 0.5-4; CA, BA, SR, <4 (FOR EACH ITEM); AL, <1.5; FAITH, THE REST. THE LATE TREATMENT OF THE BASE FOUNDRY IS EFFECTED BY THE INTRODUCTION OF THE DISMANTLED ADDITIVE IN THE CAST IRON CAST, AT THE ENTRANCE OF THE MOLD, OR BY THE TECHNIQUE KNOWN AS "IN MOLD".
