Electric Arc Furnace Processes
1997The electric arc furnace processing of oxide ceramics is a well-established and widely-used industrial technology. Raw materials are readily melted together by joule and radiant heating to form substantially large liquid volumes. These are refined if necessary with carbon and additions of metal scavenging agents such as iron, and the product is then ...

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。

Arc-Furnace Control by Regulex Exciters
Transactions of the American Institute of Electrical Engineers, 1943FOR a number of years prior to the present urgency for the production of high-quality steel, the development in control methods for electric-arc furnaces remained substantially stationary in this country. These devices were in the general form of vibrating regulators or contact-making ammeters which rapidly connected the electrode motors to and ...

Selection of the Quantum constructive scheme as a basis for a fuel arc furnace—FAF is justified. Main calculated parameters and performances of the FAF of 100 tons tapping weight equipped with the proposed systems for high-temperature scrap preheating and oxygen bath blowing at the slag-metal interface are given.

1989
The tapping of electric furnaces is a hot, physically demanding, and potentially dangerous job. Noise levels often exceed the OSHA limits. To improve the work environment as well as improve productivity, several electric furnaces in Japan worked together with the Tokyo Institute of Technology to develop remote controlled manipulators for tapping.

The 3-phase electric arc furnace
Electrical Engineering, 1933The 3-phase electric arc furnace has established itself definitely as an important industrial unit in the production of ferrous materials. With the efficiency of the arc furnace being increased, and with the overall cost of installation and operation now being comparable with that of an equivalent open hearth, an even more extensive application is ...

Symmetry of Arc Furnace Operation
Steel in Translation, 2017The electrical asymmetry in the operation of arc furnace with an asymmetric triangular configuration of the electrodes is noted. Experimental data from the DSP-100 furnace permit analysis of how the electrical parameters affect the arc characteristics.
