Abstract

La presente invención se refiere a un método de fundición continua de una banda metálica delgada que incluye mover la banda delgada a una sección de enfriamiento que tiene una pluralidad de puertos de descarga de refrigerante configurados para descargar un flujo de refrigerante a lo largo de la banda delgada; detectar inicialmente la temperatura de la banda delgada para determinar una distribución de temperatura a lo ancho de la banda delgada, y producir una señal de sensor correspondiente a una temperatura detectada en cada primera pluralidad de ubicaciones. El método incluye también controlar individualmente el enfriamiento de la banda delgada a lo ancho de la banda delgada mediante la pluralidad de puertos de descarga de refrigerante en cada zona de una primera hilera utilizando la distribución de temperatura determinada a una temperatura prácticamente constante antes de enfriar adicionalmente la banda para alcanzar cualquier temperatura de transformación de fase deseada para alcanzar una microestructura prácticamente uniforme en la banda delgada.
