The Phosphorus Reaction in Oxygen Steelmaking ...

The BOF slag can be recycled to a sinter plant or directly to the blast furnace, ultimately increasing the phosphorus input in the process. In order to meet new demands for phosphorus control, it is necessary to improve our understanding on the thermodynamics and kinetics of the phosphorus partitioning reaction between slag and metal melts during steelmaking. Therefore, the present work has ...

Slag: From By-product to Valuable Construction .

Slag has a double role: it permits removal of impurities, known as gangue, from the melt by forming oxides. It also allows exchange reactions with the liquid metal, permitting control of the process in order for the desirable elements to stay in the melt while the others are removed. (The ore beneficiation process at a mine is designed to remove as much waste and penalty elements as possible ...

Utilization Optimization of Ferroalloys during .Traduire cette page

Ferroalloys are added to liquid steel to carry out the de-oxidation process of removal of excess oxygen (O2) from the liquid steel. They have high affinity for O2 and form oxides in the form of slag. Ferroalloys are usually classified into two groups namely (i) bulk ferroalloys, and (ii) noble or special ferroalloys. Bulk ferroalloys consist of principal alloys namely ferro manganese (Fe-Mn ...

The viscosity of the slag needs to be such that removal from the metal surface is easy. At the same time, a fluid slag of low melting point promotes 1. good slagging reactions and prevents buildup in channel furnace throats and loops as well as coreless furnace sidewalls. Slags must have a high interfacial surface tension to prevent refractory attack (wetting) and to facilitate their removal ...

Mineral CO2 Sequestration by Steel Slag .

Mineral CO2 sequestration, i.e., carbonation of alkaline silicate Ca/Mg minerals, analogous to natural weathering processes, is a possible technology for the reduction of carbon dioxide emissions to the atmosphere. In this paper, alkaline Ca-rich industrial residues are presented as a possible feedstock for mineral CO2 sequestration. These materials are cheap, available near large point ...

Low-tantalum tin slags, on the other hand, are first melted in an electric-arc furnace with the addition of a flux material, and the tantalum-niobium content is collected as a ferroalloy. The tantalum-rich ore or ferroalloy is then crushed, ground, and decomposed in hydrofluoric acid. This is followed by a liquid-liquid extraction process, in which the two metals are dissolved in a slightly ...

Slag RemoverTraduire cette page

Slag remover is a material used to remove impurities in molten iron or molten steel in steelmaking or casting. Its main components are SiO2, Al2O3 and so on. The general deslagging agent has the function of heat preservation and covering. Its working principle is to adsorb and accumulate various oxides in the smelting process to facilitate removal. Slag remover expands or melts under high ...
