Electroslag Remelting of Manganese

1991
The achievable level of service characteristics of manganese-based microalloyed steels is determined mainly by their purity. The Mr-O brand of electrolytic manganese that is used for these alloys requires additional refining due to its high content of sulfur and dissolved gases. Additional refining is usually performed by radiofrequency induction (RFI)

Calcination of Slags for Electroslag Remelting

Journal of Iron and Steel Research International, 2010
The hydrides in industrial lime, alumina, magnesia, and calcium fluoride were investigated through differential thermal analysis and X-ray diffraction, and their mass losses during heating up were studied by thermogravimetric analysis method. The results indicate that the industrial alumina, lime, and magnesia, which have more moisture or hydride and ...

The behavior of hydrogen in electroslag remelting

Metallurgist, 1977
A number of studies have found that sources of hydrogen in ESR are water vapors in the mold atmosphere, flux moisture content and hydrogen from the consumable electrode. The ESR process is generally conducted with highly active basic slags capable of absorbing substantial amounts of moisture.

Solidification of electroslag-remelted ingots

JOM, 1971
The electroslag remelting process has been investigated from the point of view of ingot solidification, and experiments have been dOMe in both the laeoratory and pilot plant. The depth of the pool and its relation to the structure are described. Dipping of the electrode, switching off the current, and electrode changing all give rise to changes in the ...

Electroslag Remelting at the “Elektrostal” Plant

1991
The “Elektrostal” plant currently uses several single-phase, OKB-905-type, electroslag remelting (ESR) installations that produce two sizes of round ingots, 0.25 and 0.42 m in diameter and 0.5 and 1.4 tons in weight respectively, and an OKB-906, three-phase installation that produces 4.2-ton ingots, 0.7 m in dia­meter.

Electroslag Remelting

2008
Abstract Electroslag remelting (ESR) is commonly used to produce the highest levels of quality in plate steels, particularly in thick plates. This article provides an overview of the ESR and discusses the major components and operations of the ESR furnaces.

Advantages Of Electroslag Remelted Steels

Offshore Technology Conference, 1977
INTRODUCTION The rigors of modern design require the use of material with high reliability. The high stresses in the complex stress states that are used in present-day structures are such that materials must be used to their maximum capability. There are two methods by which these structures can be designed.

Improving the electroslag remelting of steel and alloys

Steel in Translation, 2008
Electroslag remelting (ESR) has now been in use for 50 years. In 1958, the world’s first industrial ESR furnaces went into operation at Deneprospetsstal electrometallurgical plant (Zaporozh’e, Ukraine) and the NKMZ heavy-manufacturing plant (Kramatorsk,

Review on Modeling and Simulation of Electroslag Remelting

steel research international, 2017
The Electroslag Remelting (ESR) is an advanced technology for the production of high quality materials, for example, hot work tool steels or nickel base alloys. In the past years, several models are developed aiming to predict the way in which the operational parameters affect the structure and chemical composition of the final ESR ingot.

Thermodynamics of hydrogen in electroslag remelting

2010
Oxide ion activities in binary CaF₂ - CaO and ternary, CaF₂ -CaO - Al₂O₃ and CaF₂ - CaO -SiO₂, slags were determined by CO₂-slag equilibrium experiments at 1400°C. The carbonate capacity of these slags was computed and compared with the sulfide1 capacity data available in the literature.
