Abstract
METODO PARA PREPARAR UNA PLACA DE ACERO CON POR LO MENOS 1% DE Ni, COMPUESTA POR MARTENSITA Y BAINITA DE GRANO FINO TEMPLADA O MEZCLAS; EL METODO CONSISTE EN: a) CALENTAR UNA LAJA DE ACERO A UNA TEMPERATURA DE 955�C A 1065�C PARA i) HOMOGENIZAR LA LAJA DE ACERO; ii) DISOLVER TODOS LOS CARBUROS Y CARBONITRUROS DE NIOBIO Y VANADIO Y iii) ESTABLECER LOS GRANOS FINOS DE AUSTENITA INICIALES; b) REDUCIR LA LAJA DE ACERO PARA FORMAR LA PLACA DE ACERO EN UNA O MAS PASADAS DEL LAMINADOR EN CALIENTE, DENTRO DE UN PRIMER LIMITE DE TEMPERATURA, DONDE RECRISTALIZA LA AUSTENITA; c) REDUCIR ADICIONALMENTE LA PLACA DE ACERO EN UNA O MAS PASADAS DEL LAMINADOR EN CALIENTE DENTRO DE UN SEGUNDO LIMITE DE TEMPERATURA DEBAJO DE LA TEMPERATURA EN LA CUAL LA AUSTENITA NO SE CRISTALIZA Y ENCIMA DE LA TEMPERATURA A LA CUAL LA AUSTENITA SE TRANSFORMA EN FERRITA; d) AMORTIGUAR LA VELOCIDAD DE ENFRIAMIENTO DE LA PLACA DE ACERO EN 10�C/seg-40�C/seg HASTA UNA TEMPERATURA DE TRANSFORMACION DE AUSTENITA A MARTENSITA; e) DETENER LA AMORTIGUACION; f) TEMPERAR LA PLACA DE ACERO A UNA TEMPERATURA DE TEMPLADO DESDE 400�C A ALREDEDOR DE LA TEMPERATURA DE TRANSFORMACION DE AUSTENITA A FERRITA O A FERRITA MAS CEMENTITA DURANTE UN TIEMPO PARA OCASIONAR LA PRECIPITACION DE PARTICULAS DE ENDURECIMIENTO, OBTENIENDO MARTENSITA Y BAINITA DE GRANO FINO TEMPLADAMETHOD FOR PREPARING A STEEL PLATE WITH AT LEAST 1% Ni, CONSISTING OF MARTENSITE AND TEMPERED FINE GRAIN BAINITE OR MIXTURES; THE METHOD CONSISTS OF: a) HEATING A STEEL SLAB TO A TEMPERATURE OF 955�C TO 1065�C TO i) HOMOGENIZE THE STEEL SLAB; ii) DISSOLVE ALL THE CARBIDES AND CARBONITRIDES OF NIOBIO AND VANADIUM AND iii) ESTABLISH THE INITIAL FINE GRAINS OF AUSTENITE; b) REDUCE THE STEEL SLAB TO FORM THE STEEL PLATE IN ONE OR MORE PASSES OF THE HOT ROLLING MACHINE, WITHIN A FIRST TEMPERATURE LIMIT, WHERE THE AUSTENITE RECRISTALIZES; c) ADDITIONALLY REDUCE THE STEEL PLATE IN ONE OR MORE PASSES OF THE HOT ROLLER WITHIN A SECOND TEMPERATURE LIMIT BELOW THE TEMPERATURE IN WHICH AUSTENITE DOES NOT CRYSTALIZE AND ABOVE THE TEMPERATURE TO WHICH AUSTENITE ENFORMS IS TRANSFORMED ; d) DAMPER THE COOLING SPEED OF THE STEEL PLATE BY 10�C / sec-40�C / sec UNTIL A TRANSFORMATION TEMPERATURE FROM AUSTENITE TO MARTENSITE; e) STOP THE CUSHIONING; f) TEMPERATURE THE STEEL PLATE TO A TEMPERATURE OF TEMPERATURE FROM 400�C TO AROUND THE TEMPERATURE OF TRANSFORMATION FROM AUSTENITE TO FERRITE OR TO A MORE CEMENTIAL FERRITE DURING A TIME TO CAUSE THE PRECIPITATION OF PARTICLES OF HARDENING AND ENDURING SEASONING GRANITE, OBTENGING TEMPERATURE GRINITE.
