Abstract

PROCEDIMIENTO PARA EL ACABADO DE LOS RIELES DE FERROCARRIL, EN PARTICULAR, PROCEDIMIENTO PARA LA RELAJACION DE LAS TENSIONES Y PARA EL ENDEREZADO DE LOS RIELES DE CARACTERISTICAS CORRIENTES, TRATADOS TERMICAMENTE, O EXTRA-DUROS ALEADOS.CONSISTE EN SOMETER EL RIEL DE ACERO A UNA TENSION DE TRACCION SUPERIOR AL LIMITE CONVENCIONAL DE ELASTICIDAD DEL ACERO, HASTA UN VALOR DE LA TENSION CORRESPONDIENTE A UNA DEFORMACION PLASTICA TOTAL DEL CONJUNTO DEL RIEL. DICHA TENSION DE TRACCION, DESPUES DE SU RELAJAMIENTO, PRODUCE UN ALARGAMIENTO RESIDUAL COMPRENDIDOENTRE EL 0,5 Y EL 0,7.
