Abstract

Procedimiento de fusión en continuo de productos metálicos sólidos para la producción de acero en un reactor con dos zonas distintas, comprendiendo el reactor una zona de fusión y una zona de tratamiento metalúrgico, en el cual en la zona de fusión, los productos metálicos sólidos son calentados en continuo hasta la fusión de los productos sólidos y los productos fundidos así obtenidos son transferidos a medida que se funden a la zona de tratamiento metalúrgico, comprendiendo dicho procedimiento en un mismo recipiente de la zona de tratamiento metalúrgico una sucesión de etapas que consisten en: a) afinar las productos fundidos en un medio de escoria oxidante, b) separar la escoria de la zona de tratamiento metalúrgico de la escoria de la zona de fusión, c) transformar dicha escoria oxidante en dicha escoria reductora, d) desulfurar los productos fundidos en un medio de escoria reductora, e)
