Title (EN) FURNACE FOREHEARTH ELECTRODE GROUPS
(FR) GROUPES ELECTRODES D"AVANT-CORPS DE FOUR
Abstract: front page image
(EN)In a melting furnace forehearth, having opposed electrodes arranged in groups immersed in the melted material such that heating is produced by Joule effect, cross firing between adjacent electrode groups frequently occurs. The cross firing is reduced by connecting the opposed electrodes to a multiphase power source so that the phase relationship between groups of adjacent electrodes along the forehearth (5) is less than 90 and typically 60 . The electrode groups may be arranged along the path of molten material movement in the forehearth (5) and produce a current across the forehearth (5). The electrodes may be arranged to enter from the bottom, side or top the forehearth channel.
(FR)Dans un avant-creuset ou canal de distribution d"un four de fusion, ayant des electrodes opposees disposees en groupes immerges dans le materiau en fusion ou le chauffage est produit par effet Joule, des amorcages entre groupes d"electrodes adjacentes ont frequemment lieu. Les amorcages sont reduits en connectant les electrodes opposees a une source d"energie a multiphases de telle sorte que le dephasage entre les groupes d"electrodes adjacentes le long de l"avant-creuset (5) soit inferieur a 90 et, d"une maniere caracteristique, de 60 . Les groupes d"electrodes peuvent etre disposes le long du chemin du materiau en fusion en mouvement dans l"avant-creuset (5) et produire un courant en travers de l"avant-corps (5). Les electrodes peuvent etre disposees de maniere a entrer par le fond, le haut ou les cotes du canal de l"avant-creuset.
