Abstract

La presente invención proporciona un método para controlar TI extremadamente bajo en acero con AlSi reposado extra bajo en carbono, el porcentaje en peso de la composición química del acero con AlSi reposado extra bajo en carbono comprende: C = 0.005 %, Si: 0.1-3.4 %, Mn: 0.1-0.5 %, P = 0.2 %, S = 0.002 %, Al: 0-1.2 %, N= 0.005 %, Ti = 0.0015 y un balance que es sustancialmente Fe e impurezas inevitables; el acero líquido que tiene dicha composición química se obtiene mediante el preprocesamiento de metal caliente, fundido, fundido de RH retenido y formación de lingotes, en donde se modifica la escoria del cucharón de fundición, y se agregan modificadores con base en calcio-aluminio de 0.6-1.7 kg/t de acero, con el fin de asegurar una demanda controlada que cuando se termina la descarburación de RH refinado, el contenido de T.Fe en la composición de escoria de cucharón superior = 5 %, el contenido de Al203 = 23 %; cuando se termina la descarburación de RH refinado, se emplea ferrosilicio, ferroaluminio o ferromanganeso para realizar desoxidación y aleación, luego realizar una desulfuración profunda, y la eficiencia de desulfuración es 50 % a 70 %.
