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.A COLD ROLLED STEEL SHEET, WHICH MAY BE GALVANIZED LATER IF DESIRED, IS PRODUCED THROUGH HOT ROLLED STEEL CONTAINING, ON A MASS BASE, 0''0010 TO 0''0040 DE C, AT THE ADDITION 0''0030% FROM N, TO THE SUM 0''5% OF YES, 0''02 TO 1''5% OF MN, TO THE SUM OF 0''08% OF P, TO THE SUM OF 0''01% OF S, 0 '' 005 TO 0''07% OF SOLUBLE ACID TO, AT THE SUM OF 0''05% OF NB (WHERE 0 <NB% BALANCE OF FAITH AND INEVITABLE IMPURITIES AT A TERMINATION TEMPERATURE OF THE TRANSFORMATION POINT AR3 OR HIGHER , RAPIDLY COOLING THE STEEL IN 2 S. AFTER HOT ROLLING, AT A COOLING RATE OF 30 THAT THE TEMPERATURE DECREASES UP TO, AT LEAST, 100 DO TO 650 72 TO 92%, TAKING THE CRYSTALLIZATION OF 820 TO 880 TA TEMPERATURE UNTIL ROOM TEMPERATURE, AT A COOLING RATE OF 3 C / S AT LEAST THE SHEET OBTAINED CONTAINS CARBON IN THE FORM OF SOLID SOLUTION FORMED BY THE DISSOLUTION OF CARBIDE DEPOSITED IN THE RECRISTAL COATING. TION, AND HAS A RECRISTALIZATION TEXTURE IN WHICH THE VALUE OF THE LOG (I {222} / I {200} IS 2''7 OR HIGHER, WHERE I {222} AND I {200} ARE THE DIFFACTION INTENSITIES OF THE PLANE { 222} AND OF THE PLANE {200} RESPECTIVELY, IN DIFRACTOMETRY. THE SHEET IS EXCELLENT IN CONFORMABILITY AND PRACTICABILITY IN CHEMICAL CONVERSION COATING AND COOKING TEMPERABILITY AND WORK TEMPLABILITY.
