Abstract

Que comprende:un metodo de produccion de un acero fundido de alta resistencia al desgaste con microestructura mayoritariamente bainitica y un balance adecuado de tenacidad y dureza para piezas de gran tamano en operaciones mineras tales como molienda y chancado, cuya composicion quimica, expresada en porcentajes en peso, comprende: 0,30-0,40%C, 0,50-1,30%Si, 0,60-1,40%Mn, 2,30-3,20%Cr, 0,0-1,00%Ni, 0,25-0,70%Mo, 0,0-0,50%Cu, 0,0-0,10%Al, 0,0-0,10%Ti, 0,0-0,10%Zr, menos de 0,050%P, menos de 0,050%S, menos de 0,030%N, opcionalmente menos de 0,050%Nb, opcionalmente 0,0005-0,005%B, opcionalmente 0,015-0,080% de metales de tierras raras, y contenidos residuales de W, V, Sn, Sb, Pb y Zn menores a 0,020%, y el balance de hierro. El metodo de produccion del acero fundido incluye fusion 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 normalizado y revenido. El acero fundido descrito exhibe un balance adecuado de la composicion quimica, tenacidad y templabilidad para asegurar endurecimiento completo en piezas fundidas de gran tamano, tipicamente hasta 17 pulgadas de espesor, con dureza brinell entre 385-495 BHNIt comprises: a method of production of a cast steel with high resistance to wear and tear with mostly bainitic microstructure and an adequate balance of toughness and hardness for large parts in mining operations such as grinding and crushing, whose chemical composition, expressed in percentages in weight, comprises: 0.30-0.40% C, 0.50-1.30% Si, 0.60-1.40% Mn, 2.30-3.20% Cr, 0.0-1, 00% Ni, 0.25-0.70% Mo, 0.0-0.50% Cu, 0.0-0.10% Al, 0.0-0.10% Ti, 0.0-0, 10% Zr, less than 0.050% P, less than 0.050% S, less than 0.030% N, optionally less than 0.050% Nb, optionally 0.0005-0.005% B, optionally 0.015-0.080% rare earth metals, and residual contents of W, V, Sn, Sb, Pb and Zn less than 0.020%, and the iron balance. The molten steel production method includes melting and heat treatment. The fusion can be carried out in an electric arc furnace with basic or acid refractory or an electric induction furnace. Electric arc furnace melting as normal operation comprises melting, oxygen blowing, blocking, refining and deoxidation. The fusion in an electric induction furnace comprises fusion, refining, control of the nitrogen in solution and deoxidation. The heat treatment comprises normalizing and tempering. The cast steel described exhibits an adequate balance of chemical composition, toughness, and hardenability to ensure complete hardening in large-size castings, typically up to 17 inches thick, with brinell hardness between 385-495 BHN.
