Title (EN) SYSTEMS AND METHODS FOR ELECTRODE COOLING IN AN ELECTRIC ARC FURNACE USING WASTEWATER
(FR) SYSTÈMES ET PROCÉDÉS DE REFROIDISSEMENT D'ÉLECTRODES DANS UN FOUR À ARC ÉLECTRIQUE À L'AIDE D'EAUX USÉES
Abstract:
(EN) Systems and methods for cooling an electric arc furnace (EAF) using wastewater. Some methods include heating a material disposed with an interior volume an EAF by supplying power to one or more electrodes of the EAF, each being at least partially disposed within the interior volume, and cooling the one or more electrodes using wastewater by transferring heat from the one or more electrodes to the wastewater. Some methods include passing the wastewater through a filter to reduce a total suspended solids content of the wastewater.
(FR) L'invention concerne des systèmes et des procédés de refroidissement d'un four à arc électrique (EAF) à l'aide d'eaux usées. Certains procédés consistent à chauffer un matériau disposé dans un volume intérieur d'un EAF en fournissant de l'énergie à une ou à plusieurs électrodes de l'EAF, chacune étant au moins partiellement disposée à l'intérieur du volume intérieur, et à refroidir les électrodes à l'aide d'eaux usées, par transfert de chaleur des électrodes aux eaux usées. Certains procédés consistent à faire passer les eaux usées à travers un filtre, afin de réduire la teneur totale en solides en suspension dans les eaux usées.
