Abstract
Un forno ad arco comprendente un recipiente del forno avente un asse trasversale ed un asse centrale, elettrodi disposti su una circonferenza graduata, gli elettrodi sporgendo nel recipiente del forno paralleli all'asse centrale verticale, gli elettrodi sono montati su un dispositivo di supporto degli elettrodi di tre colonne di supporto e tre bracci di supporto, il centro è collocato sull'asse trasversale ad una distanza predeterminata dal centro, l'asse trasversale essendo colineare con quello intermedio dei bracci di supporto, un elettrodo è disposto più vicino alle colonne di supporto nella intersezione dell'asse trasversale e della circonferenza graduata, e gli altri elettrodi sono disposti sulla circonferenza graduata secondo un angolo ?=<110° con l'elettrodo nel centro della circonferenza.
