CONTAINER MADE OF ALUMINUM AND STAINLESS STEEL FOR FORMING SELF-BAKING ELECTRODES FOR USE IN LOW ELECTRIC REDUCTION FURNACES

摘要

The present invention relates to a self-baking electrode for use in low electric reduction furnaces, and refers particularly to a container (1) for the formation of self-baking electrodes to be used in low electric reduction furnaces, allowing the manufacture of silicon alloys with iron content as low as 0.25 %, the container comprising an aluminum cylindrical casing (11) split in two parts containing therein a plurality of stainless steel ribs (12) uniformly attached perpendicularly along the inner surface of the casing (11) lengthwise along the cylindrical casing, characterized by the fact that the cylindrical casing (11) is made of aluminum plates and the ribs (12) are made of stainless steel plates. The invention also relates to a method of forming a self-baking electrode using this container as well as the electrode formed thereby. Finally, the invention relates to the use of a self-baking electrode formed in this container for manufacturing silicon alloys.
