Abstract

Esta invencion se refiere al método y al equipo para la adicion continua o discontinua de materiales de reaccion/inoculacion necesarios para la desulfuracion o la produccion de hierro ductil, obtenible durante el paso del hierro base a través de una pileta o cuba que contiene la cámara para la fusion, vaporizacion y distribucion de los materiales de reaccion-inoculacion hacia el fundido (por ejemplo, vapor de magnesio-Ferrum Silicon). El tratamiento puede ser conducido continuamente para cantidades ilimitadas o libremente definibles o hierro.
