Abstract

EL INVENTO SE REFIERE A UN PROCEDIMIENTO PARA EL TEMPLADO POBRE EN DEFORMACIONES DE CIGUEÑALES POR CALENTAMIENTO ELECTROINDUCTIVO SECUENCIAL DE LAS SUPERFICIES DE APOYO, SEGUIDO DE UN ENFRIAMIENTO BRUSCO. EL INVENTO SE CARACTERIZA POR EL HECHO DE QUE CON SOLO DOS INDUCTORES SE TEMPLAN TODOS LOS APOYOS, TEMPLANDOSE AL MISMO TIEMPO DOS APOYOS SITUADOS SIMETRICAMENTE CON RELACION AL CENTRO DEL EJE.
