Electric Arc Behaviour in Steelmaking Arc Furnaces
DENKI-SEIKO[ELECTRIC FURNACE STEEL], 1967 製鋼用アーク炉の生産性向上について,最近いろいろな研究が進められているが,基本的なアーク現象の研究は2, 3の報告がされているにすぎず,アーク炉のアーク,すなわち,大電流アーク現象については十分に解析されていないのが現状である。今回,小型3相アーク炉(容量100kgおよび2t)で,16mm高速度撮影装置を用いて毎秒3,000～4,000コマ/秒の速度で炉操業中のアークを撮影し,そのアーク現象を観察検討した結果,アーク現象に極性の影響が大きいこと,アークフレアが主に電極から生じているらしいこと,電極先端形状の相違によってアーク現象が大きく支配されることなどがわかった。また4'径電極では中空電極の効果が観察できた。
