Abstract

UNA LAMINA DE ACERO LAMINADA EN FRIO, QUE PUEDE POSTERIORMENTE GALVANIZARSE SI SE DESEA, SE PRODUCE MEDIANTE ACERO CILINDRADO EN CALIENTE CONTENIENDO, SOBRE UNA BASE MASA, 0''0010 A 0''0040 DE C, A LO SUMO 0''0030% DE N, A LO SUMO 0''5% DE SI, 0''02 A 1''5% DE MN, A LO SUMO 0''08% DE P, A LO SUMO 0''01% DE S, 0''005 A 0''07% DE ACIDO SOLUBLE AL, A LO SUMO 0''05% DE NB (DONDE 0 < NB % EQUILIBRIO DE FE E IMPUREZAS INEVITABLES A UNA TEMPERATURA DE TERMINACION DEL ACABADO DEL PUNTO DE TRANSFORMACION AR3 O SUPERIOR, ENFRIANDO RAPIDAMENTE EL ACERO EN 2 S. DESPUES DEL CILINDRADO EN CALIENTE, A UN RITMO DE ENFRIAMIENTO DE 30 QUE LA TEMPERATURA DESCIENDA HASTA, AL MENOS, 100 DO A 650 72 AL 92%, LLEVANDO EL RECOCIDO DE LA CRISTALIZACION A 820 HASTA 880 TA TEMPERATURA HASTA LA TEMPERATURA AMBIENTE, A UN RITMO DE ENFRIAMIENTO DE 3 C/S POR LO MENOS. LA LAMINA OBTENIDA CONTIENE CARBONO EN FORMA DE SOLUCION SOLIDA FORMADA MEDIANTE LA DISOLUCION DE CARBUROS DEPOSITADOS EN EL RECOCIDO DE LA RECRISTALIACION, Y TIENE UNA TEXTURA DE RECRISTALIZACION EN LA QUE EL VALOR DEL LOG (I{222}/I{200} ES 2''7 O SUPERIOR, DONDE I{222} Y I{200} SON LAS INTENSIDADES DE DIFRACCION DEL PLANO {222} Y DEL PLANO {200} RESPECTIVAMENTE, EN DIFRACTOMETRIA. LA LAMINA ES EXCELENTE EN CONFORMABILIDAD Y PRACTICABILIDAD EN REVESTIMIENTO DE CONVERSION QUIMICA Y TEMPLABILIDAD DE COCIMIENTO Y TEMPLABILIDAD DE TRABAJO.
