Abstract
"RECIPIENTE PARA A FORMAçãO DE ELETRODOS DEAUTOCOZIMENTO PARA USO EM BAIXOS FORNOSELéTRICOS DE REDUçãO". A presente invenção se relaciona aum eletrodo de autocozimento para uso em baixos-fornos elétricosde redução, e particularmente refere-se a um recipiente (1) para aformação de eletrodos de autocozimento para a utilização embaixos-fornos elétricos de redução, que possibilita a fabricação deligas de silício com conteúdo de ferro de até 0,35%,compreendendo um invólucro cilíndrico bipartido (11) contendo emseu interior uma pluralidade de aletas (12) uniformemente fixadasde modo perpendicular ao longo da superfície interna doinvólucro(11) no sentido longitudinal do invólucro cilíndrico,caracterizado pelo fato de que o invólucro cilíndrico (11) e asaletas (12) são construídos de chapas de aço inox. A invençãoainda se relaciona a um processo de formação de um eletrodo deauto-cozimento usando este recipiente assim como o eletrodoformado pelo mesmo. Finalmente, a invenção se refere ao uso deum eletrodo de auto-cozimento formado neste recipiente parafabricar ligas de silício."CONTAINER FOR THE FORMATION OF SELF-COOKING ELECTRODES FOR USE IN LOW REDUCTION OVENS". The present invention relates to a self-baking electrode for use in electric reduction furnaces, and in particular it concerns a container (1) for forming self-baking electrodes for the use of electric reduction furnaces, which allows the manufacture of alloys of silicon with an iron content of up to 0.35%, comprising a bipartite cylindrical shell (11) containing a plurality of fins (12) uniformly fixed perpendicularly along the inner surface of the shell (11) in the longitudinal direction of the cylindrical shell , characterized by the fact that the cylindrical casing (11) and wings (12) are constructed of stainless steel sheets. The invention further relates to a process of forming a self-cooking electrode using this container as well as the electrode formed by it. Finally, the invention relates to the use of a self-cooking electrode formed in this container to manufacture silicon alloys.
