Abstract

DONDE EL PROCEDIMIENTO COMPRENDE SOMETER LA CHAPA A UN TRATAMIENTO TERMICO DE TEMPLE, EN EL CALENTAMIENTO DE LA LAMINACION O DESPUES DE LA AUSTENITIZACION EN UN HORNO; QUE CONSISTE EN: a) ENFRIAR LA CHAPA A UNA VELOCIDAD DE ENFRIAMIENTO SUPERIOR A 0,5°C/s ENTRE UNA TEMPERATURA SUPERIOR A AC3 y UNA TEMPERATURA COMPRENDIDA ENTRE T=800-270*C'-90*Mn-37*Ni-70*Cr-83*(Mo+W/2) y T-50°C; b) ENFRIAR LA CHAPA A UNA VELOCIDAD DE ENFRIAMIENTO EN EL NUCLEO Vr<1150*ep-1,7 Y SUPERIOR A 0,1°C/s ENTRE LA TEMPERATURA T y 100°C, SIENDO ep EL ESPESOR DE LA CHAPA EN mm; c) ENFRIAR LA CHAPA HASTA TEMPERATURA AMBIENTE; Y, d) EFECTUAR EVENTUALMENTE UN APLANADO. ADEMAS, SE EFECTUA UN REVENIDO A UNA TEMPERATURA INFERIOR O IGUAL A 350°C. LA CHAPA TIENE UNA COMPOSICION QUIMICA QUE COMPRENDE, EN PESO: 0,1%<C<0,23%; 0%<Si<2%; 0%<Al<2%; 0,5%<Si+Al<2%; 0%<Mn<2,5%; 0%<Ni<5%; 0%<Cr<5%; 0%<Mo<1%; 0%<W<2%; 0,05%<Mo+W/2<1%; 0%<B<0,02%; 0%<Ti<0,67%; 0%<Zr<1,34%; 0,05%<Ti+Zr/2<0,67%; 0%<S<0,15%; N<0,03%; EVENTUALMENTE DE 0% A 1,5% DE COBRE, UN ELEMENTO ESCOGIDO ENTRE Nb, Ta y V EN CANTIDADES TALES QUE Nb/2+Ta/4+V<0,5%, Y UN ELEMENTO ESCOGIDO ENTRE Se, Te, Ca, Bi, Pb EN CANTIDADES INFERIORES O IGUALES A 0,1%; SIENDO EL RESTO Fe E IMPUREZAS RESULTANTES DE LA ELABORACION. LA COMPOSICION QUIMICA CUMPLE LAS SIGUIENTES RELACIONES: C'=C-Ti/4-Zr/8+7*N/8>0,095%; Ti+Zr/2-7*N/2>0,05% y 1,05*Mn+0,54*Ni+0,5*Cr+0,3*(Mo+W/2)1/2+K>1,8 CON K=1 si B>0,0005% y K=0 si B<0,0005%
