It is expected that phosphorus-concentrated slag produced by using the pyro-reaction between high phosphorus hot metal, which was prepared reduction of usual steelmaking with a small amount and oxidizing can become an important resource instead phosphate rock. For separating from slag, citric acid leaching method has been reported to be available. In this study, effects cooling condition oxidat...

The use of industrial by-products as admixture to ASTM Type I cement (ordinary Portland cement (OPC)) was investigated with the objective of improving the solidification of organic marine clayey soils. The industrial by-products considered in this paper were oyster-shell powder (OSP), steelmaking slag dust (SMS) and fuel-gas-desulfurized (FGD) gypsum. The industrial by-products were added to OP...

A preliminary dynamic model is developed to predict the foaming phenomenon in oxygen steelmaking incorporating Computational Fluid Dynamics, which will be able to simulate the evolution of the physical properties throughout a blow and predict the foaming height with time. The computational fluid dynamic (CFD) model developed by Sattar et al (Sattar et al., 2013a, Sattar et al., 2013c, Sattar et...

One of the largest problems facing steelmaking industry is high amount waste currently produced and low that recycled. This study aims to look at suitability 3 different samples basic oxygen (BOS) slag as a construction material, in concert with their carbon capture capacity. Characterization by scanning electron microscopy (SEM), X-ray diffraction (XRD), inductively coupled plasma spectroscopy...

The argon-stirred ladle is a standard piece of steelmaking refining equipment. molten steel quality will improve when good process applied. In this paper, Multiphysics model that contained fluid flow, bubble transport, alloy heat flux, melting, and an concentration species transport was established. were used to calculate the velocity verified by hydraulic combined with particle image velocimet...

This article presents the results of a research on recycling wastes from metallurgical plants in city Pavlodar at steel smelting plant KSP Steel. The pellets were produced with aspiration dust and mixed steelmaking (white) slag, ferrous sand, scale. fired temperature 600 ° C. experience use 20% white sand 10% mill scale shows, after burning furnace, quite satisfactory strength, which is 80 kg /...
