ELECTRIC ARC FURNACE

摘要

This invention concerns an electric arc furnace (4) comprising a chamber (8) suitable for containing molten steel; a roof (12) suitable for covering the chamber (8) and for containing a mass of scrap steel; electrodes (16) suitable for melting the mass of scrap, and means of support (20) on a base (24). The latter means (20) are such as to support the chamber (8) and permit its oscillation around a horizontal axis of rotation (X-X). 'The roof (12) and the chamber (8) are counterprofiled in correspondence to the respective interface walls (30) to create a rotoidal type coupling with regard to the axis of rotation (X-X). The roof (12), during oscillation of the chamber (8), remains fixed with regard to the base (24) as well as in a closed position with regard to the chamber (8).
