Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO DE COLADA CONTINUA DE UNA BANDA DE ACERO INOXIDABLE AUSTENITICO DIRECTAMENTE A PARTIR DE METAL LIQUIDO DE COMPOSICION, EXPRESADA EN PORCENTAJES PONDERALES: C INFERIOR O IGUAL A 0,08 %; SI INFERIOR O IGUAL A 1 %; MN INFERIOR O IGUAL A 2 %; P INFERIOR O IGUAL A 0,045 %, S INFERIOR O IGUAL 0,030 %; CR COMPRENDIDO ENTRE 17,0 Y 20,0 %, NI COMPRENDIDO ENTRE 8,0 Y 10,5 % EN UNA MAQUINA DE COLADA SOBRE UNA O ENTRE DOS PAREDES MOVILES CUYA SUPERFICIE ESTA PROVISTA DE HOYUELOS Y DE LA QUE SE HACE INERTE LA ZONA QUE RODEA EL MENISCO CON UN GAS DE INERTACION DE COMPOSICION DOMINADA, CARACTERIZADO PORQUE: SE CONFIERE A DICHO METAL UNA RELACION CR{SUB,EQU}/NI{SUB,EQU} SUPERIOR A 1,55 CON CR{SUB,EQU} = % CR + 1,37 X % MO + 1,5 X % SI + 2 X % NB + 3 X % TI Y NI{SUB,EQU} = % NI + 0,31 X % MN + 22 X % C + 14,2 X % N + % CU; - SE UTILIZA UNA O VARIAS PAREDES MOVILES CUYO CONJUNTO DE LA SUPERFICIE LLEVA HOYUELOS UNIDOS DE DIAMETRO COMPRENDIDO ENTRE 100 Y 1500 {MI}M YDE PROFUNDIDAD COMPRENDIDA ENTRE 20 Y 150 {MI}M: - Y SE UTILIZA UN GAS DE INERTACION QUE CONSISTE AL MENOS PARCIALMENTE EN UN GAS SOLUBLE EN EL ACERO. LA INVENCION SE REFIERE TAMBIEN A UNA INSTALACION DE COLADA PARA LA IMPLEMENTACION DE ESTE PROCEDIMIENTO.
