Effect of Basicity on Deoxidation Capability of Refining Slag

Journal of Iron and Steel Research International, 2013
Mass action concentration (activity) calculation model was used to analyze the variation rule of mass action concentrations of slag compositions with basicity changing, and the effect of basicity on deoxidation capability and control of spinel and globular inclusions was investigated theoretically.

Stabilization of refining slags by correction of their phase composition

Steel in Translation, 2016
The stabilization of refining slags in ladle treatment with alumina fluxes is studied. In refining, the slag is stabilized in the presence of alumina fluxes thanks to isomorphic replacement of a calcium ion by alkali-metal ions and to decrease in the dicalcium-silicate content in the melt as a result of its replacement by aluminum-bearing phases.

Water vapor solubility in ladle-refining slags

Metallurgical and Materials Transactions B, 2006
A thermo-gravimetric technique was used to determine the hydrogen solubilities of some Al2O3-CaO-MgO-SiO2 quaternary slags. The focus of the work was to determine the water capacities in slags having lower SiO2 concentrations, which were relevant to industrial practices.

Slag refining of silicon and silicon alloys: a review

Mineral Processing and Extractive Metallurgy Review, 2018
ABSTRACTSilicon is considered as the most appropriate semiconductor material for manufacturing solar cells because of its abundance in the earth’s crust and its nontoxicity. One of the main concerns of the silicon industry in the past few years has been developing an environmentally and economically viable process dedicated to production of solar grade

Ductility of steel refined with liquid synthetic slag

Metal Science and Heat Treatment, 1970
1. In steel refined with liquid synthetic slag and subjected to improvement the work of crack initiation is high and remains unchanged down to −80°. 2. At negative temperatures the work of crack initiation is substantially higher for the improved steel than for the normalized steel. 3.

Processing of copper slags on the basis of electro-slag and arc-slag refinings

2014
Results of the experimental melts, confirming the extraction of copper from slag, lump and dusty wastes of copper melting production in application of processes of arc and electroslag melting are given. The percentage of copper extraction, reaching 97.9% and its content in ingot – 93…99.6 %, is shown.

The Capacities and Refining Capabilities of Metallurgical Slags

1988
After reviewing the concepts of the basicity of slags and capacities of slags, the paper describes how the two can be correlated quantitatively using the optical basicity approach. The capacities discussed are those that are relevant under the highly reducing conditions typical of foundry processes, namely the sulfide, phosphate, water, nitride ...

Desulfurization ability of refining slag with medium basicity

International Journal of Minerals, Metallurgy, and Materials, 2014
The desulfurization ability of refining slag with relative lower basicity (B) and Al2O3 content (B = 3.5–5.0; 20wt%–25wt% Al2O3) was studied. Firstly, the component activities and sulfide capacity (C S) of the slag were calculated. Then slag-metal equilibrium experiments were carried out to measure the equilibrium sulfur distribution (L

Ladle slag-refining of electric furnace steel

JOM, 1957
Striving to increase steel output per furnace as well as to improve steel quality, one of the leaders of French electric-furnace steelmaking—Ugine— has perfected a ladle slag treatment for rapid desulfurization and deoxidation. The result: tap-to-tap time reduced by more than 50 pct, and output per furnace increased by more than 200 pct.
