A Review of Slag Refining of Silicon Alloys
JOM, 2020Slag refining of silicon has been modified in recent years by combining the process with solvent refining, in which an alloy of silicon is first treated by slag and then solidified under controlled conditions to yield high-purity silicon crystals. This paper discusses the effect of alloying elements on the efficiency of slag treatment.

Research Progress of Desulfurization Refining Slag: A Review
steel research international, 2023The development of refining slag is the core of the ladle furnace (LF) refining processes and is essential for fast and effective desulfurization refining. Desulfurization reactions are mainly determined by slag–steel interactions, which are closely related to the physicochemical properties of slags.

A Review of Slag Refining of Crude Silicon
JOM, 2020Metallurgical refining of crude silicon for low-cost, mass production of solar silicon has been studied extensively over the past two decades. One of the methods attempted to target the deleterious impurities of Si is slag refining, where liquid Si or its alloys are treated with a flux.

The Slagging Model Research of Refining-Slag for High Aluminum Steel
Advanced Materials Research, 2012To accurately control the Si content and ensure the function of slag refining in high aluminum steel, the direction and limits of reduction reaction for SiO2 were analyzed based on the thermodynamics. In addition, the thermodynamic prediction model of multi-element slag was studied.

Refining Slag Treatment with Flotation Cell
Advanced Materials Research, 2014In past years, the exploitation of mineral resource in our country was stressed on capacity and the solid waste recycle and innocent treatment was ignored. Much valuable metal is associated and coexist with waste, it is in difficult position for present technology to recycle valuable composition in that waste, which leads to valuable component loss and

A Model for Slag Eyes in Steel Refining Ladles Covered with Thick Slag
Metallurgical and Materials Transactions B, 2014During inert gas stirring in steel ladles, the overlying slag is pushed to the side by the rising gas-metal plume, resulting in an open eye of exposed steel. The present work is devoted to the modeling of ladle eyes in a bath covered with a thick slag layer, where the eyes formed are often smaller than the cross-section of the gas-metal plume.

Effect of Basicity on Deoxidation Capability of Refining Slag
Journal of Iron and Steel Research International, 2013Mass 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.

Slag refining of silicon and silicon alloys: a review
Mineral Processing and Extractive Metallurgy Review, 2018ABSTRACTSilicon 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, 19701. 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.
