Industrial electroheating equipment - Test methods for direct arc furnaces

This International Standard specifies test procedures, conditions and methods according to which the main parameters and the main operational characteristics of electric arc furnaces (EAF) operated either with alternating current (EAFac) or with direct current (EAFdc) with a capacity above 500 kg/heat are established. The EAF technology is also applicable to furnaces, in which liquid metal is kept at high temperature or superheated to casting temperature (e.g. in a ladle furnace (LF), operated with alternating current). Test methods for some special equipment, e.g. controlled rectifiers for EAFdc, are covered by IEC 60146-1-1. Test methods for submerged arc furnaces (SAF) are covered by IEC 60683.

Chauffage électrique industriel - Méthodes d'essai des fours à arc direct

La CEI 60676:2011 spécifie les procédures, les conditions et les méthodes d'essai suivant lesquelles sont établis les principaux paramètres et les principales caractéristiques de fonctionnement des fours à arc électrique (FAE), soit à courant alternatif (FAE c.a.), soit à courant continu (FAE c.c.), dont la capacité est supérieure à 500 kg/charge de fusion. Cette troisième édition annule et remplace la précédente édition parue en 2002 et constitue une révision technique. Les principales modifications techniques par rapport à l'édition précédente sont les suivantes:  - Article 1 (Domaine d'application et objet) - les types de fours sont définis de façon plus claire.  - L'Article 2 (Références normatives) et l'Article 3 (Termes et définitions) ont été mis à jour et complétés.  - Un nouvel Article 4 (Caractéristiques des fours à arc électrique (FAE)) a été ajouté; il se concentre principalement sur les essais nécessaires pour l'appareillage électrique à haute tension/haute intensité de l'installation.  - L'Article 5 (Type des essais et conditions générales d'exécution) et l'Article 6 (Essais techniques) ont été modifiés pour s'adapter aux exigences actuelles relatives à la sécurité de fonctionnement d'un four à arc électrique.

Oprema za industrijsko električno ogrevanje - Preskusne metode za peči z odkritim oblokom

Ta mednarodni standard določa preskusne postopke, pogoje in metode, po katerih so vzpostavljeni glavni parametri in glavne značilnosti peči z odkritim električnim oblokom (EAF), ki delujejo z izmeničnim tokom (EAFac) ali enosmernim tokom (EAFdc) z zmogljivostjo nad 500 kg/enoto toplote. Tehnologija EAF se uporablja tudi za peči, v katerih se tekoča kovina vzdržuje na visoki temperaturi ali segreje na temperaturo vlivanja (npr. v ponovčni peči (LF), ki deluje z izmeničnim tokom). Preskusne metode za nekatere vrste posebne opreme, npr. nadzorovane usmernike za EAFdc, so zajete v standardu IEC 60146-1-1. Preskusne metode za peči z zakritim oblokom (SAF) so zajete v standardu IEC 60683.
