Abstract
Patente de Invenção para <B>"PROCESSO PARA A FUSãO EM CONTìNUO DE PRODUTOS METáLICOS SóLIDOS"<D> A presente invenção se refere ao processo de fusão em contínuo, de produtos metálicos sólidos, em um reator compreendendo uma zona de fusão e uma zona de tratamento metalúrgico, o qual consiste no aquecimento contínuo dos produtos metálicos sólidos na zona de fusão até a fusão dos produtos sólidos, na transferência gradativa dos produtos fundidos na zona de tratamento metalúrgico, no refinamento dos produtos fundidos na zona de tratamento metalúrgico no meio da escória oxidante, na separação da escória da zona de tratamento metalúrgico da escória da zona de fusão, na transformação da escória oxidante na zona de tratamento metalúrgico em uma escória redutora, na dessulfurização dos produtos fundidos na zona de tratamento metalúrgico em um meio de escória redutora e no escoamento do metal fundido.
