Abstract

Que comprende: un metodo de fabricacion de un acero fundido martensitico de alta dureza y excelente resistencia al desgaste bajo condiciones de abrasion e impacto para piezas de gran tamano utilizadas como revestimientos antidesgaste en operaciones mineras de molienda y chancado, cuya composicion quimica, en porcentaje en peso, comprende 0,35-0,55%C, 0,60-1,30%Si, 0,60-1,40%Mn, 4,5-6,50%Cr, 0,0-0,60%Ni, 0,30-0,60%Mo, 0,0-0,70%Cu, 0,010-0,10%Al, 0,0-0,10%Ti, 0,0-0,10%Zr, 0,0-0,050%Nb, menos de 0,035%P; 0,035%S; 0,030%N, opcionalmente 0,0005-0,005%B; 0,015-0,080%Tierras Raras, y el balance de hierro. El metodo incluye fusion, colada y tratamiento termico. La fusion puede ser realizada en horno electrico de arco con refractario basico o acido u horno electrico de induccion. La fusion en horno electrico de arco como operacion normal comprende fusion, insuflado de oxigeno, bloqueo, afino y desoxidacion. La fusion en horno electrico de induccion comprende fusion, afino, control del nitrogeno en solucion y desoxidacion. El tratamiento termico comprende temple en aire quieto o forzado segun el espesor de las piezas, seguido de un tratamiento termico de revenido. El acero fundido descrito en conjunto con adiciones de microaleantes a fin de obtener alta templabilidad y endurecimiento completo en piezas fundidas de gran tamano, tipicamente hasta 14 pulgadas de espesor, con dureza Brinell preferentemente en torno a los 630 BHN segun las condiciones de tratamiento termico aplicadas
