In this paper, a new method of basic oxygen furnace (BOF) slag component modification with regulator was studied. The main mineral designed as C4AF, C2S and C3S in modified BOF slag, the batching method, compositions, hydration rate, activation index capability resisting sulfate corrode also were XRD, BEI EDS used to characterize formation, SEM study morphology products. results show that most ...

Electric arc furnace (EAF) dust, together with a mill scale and coke were smelted in a laboratory electric arc furnace. These metallurgical wastes consist of a many different phases and elements, making the reaction process complex. Thermo-chemical analysis of the reactions in metal, slag, and gas phases was done, and used for modeling of the mixture composition and energy consumption required ...

Abstract A tapping process model of the steel from basic oxygen furnace (BOF) addressing reactions in ladle is proposed. In model, effective equilibrium reaction zone (EERZ) method applied to describe steel/slag interfacial reaction. The bulk (steel/inclusion/lining wear) and slag (liquid slag/slag additions/lining are considered. thermodynamic library—ChemApp used perform calculation. includes...

Basic Oxygen Furnace (BOF) slag is currently utilized with low-grade applications or landfilled. Here, we investigate a novel route to upgrade BOF high-performance binder by chemical activation tri-potassium citrate. The impact of citrate on hydration and phase assemblage analyzed multi-technique approach. Results reveal that the addition considerably enhances reactivity brownmillerite accelera...

This work investigates the melting behaviour of iron ore with calcium-based fluxes, including lime, limestone and basic oxygen furnace (BOF) steelmaking slag. With an aim to explore potential k...

The modification of basic oxygen furnace (BOF) slag by adding silica can improve the properties BOF for applications in cement industry. rapid dissolution is essential to hot modification. In this work, behavior molten CaO-SiO2-Fe2O3-MgO-MnO system as synthetic was investigated using traditional rotating cylinder technique. Effects rotation speed, temperature, immersion time, and basicity on we...
