Abstract

Un metodo de produccion de tiras de acero colado que tienen baja rugosidad superficial y baja porosidad mediante la colada con acero fundido que tiene un contenido de oxigeno total de por lo menos 70 ppm y un contenido de oxigeno libre de entre 20 y 60 ppm, y una temperatura que permite a una mayoria de cualquier inclusion de oxido estar en estado liquido. El contenido de oxigeno total puede ser de por lo menos 100 ppm y un contenido de oxigeno libre de entre 30 y 50 ppm. La tira de acero producida por el metodo puede tener una densidad por unidad de area de por lo menos 120 inclusiones de oxido por milimetro cuadrado a una profundidad de aproximadamente 2 micrones desde la superficie de la tira.
