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 ...

A Laboratory Arc-Melting Furnace
Review of Scientific Instruments, 1954Using a glass resin kettle as enclosure, and an inverted-J electrode, a small arc-melting furnace was designed for conveniently melting metals under an inert atmosphere.

Electric Arc Furnace Slag Concrete
2016The aim of this section is to comprehensively investigate the possibility of substituting natural aggregates with Black/Oxidizing Electric Arc Furnace (EAF) slag, at high replacement ratios, to produce structural concrete. The properties of the slag are described in detail, in terms of chemical composition, mineralogy, microstructure and physical ...

Power company service to arc furnaces
Electrical Engineering, 1935Before an electric arc furnace, which is a rapidly fluctuating load during part of its operating cycle, is connected to an electric power distribution system, the electrical characteristics of the furnace must be known in order that the service may be provided in such a way that the resulting voltage fluctuations on the system will not exceed allowable

Control of vacuum arc furnaces
Steel in Translation, 2016Control of a vacuum arc furnace by means of a programmed step in the melting process is described. A model of voltage control in a vacuum arc furnace was considered in [1, 2]. However, the control algorithm is associated with considerable static error.

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.

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 ...

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.

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.
