Abstract

se describe la coordinacion eficiente del procesamiento (por desulfuracion) y el traslado de metal caliente desde un fundidor directo, que produce metal caliente de manera continu, auno o más hornos de arco eléctrico, que operan de manera intermitente. La presente incluye el uso de dispositivos de almacenamiento de metal caliente, tales como cazos de colada, que son suficientemente grandes para suministrar metal caliente para un pequeno numero, preferiblemente dos o tres, de operaciones de carga de horno de arco eléctrico.
