Electrode for electric arc furnaces |
摘要 |
An electrode for arc furnaces, comprising a metallic water-cooled upper section and a consumable, replaceable lower section, interconnected by means of a threaded nipple or the like. At least one light-receiving element is positioned in a zone associated with the interconnection of the cooled metal shaft and the consumable section. A light signal falling on the light-receiving element where the consumable section is in absence, is passed in a suitable manner via a light wave guide to a furnace control which activates a safety system.
