The Effect of Flux type and Oxygen Blowing on Simultaneous Removal of Phosphorus and Sulfur from Molten Iron
This research was conducted to study the effect of lime based Flux with the composition of CaO-20%CaF2-8%FeO on simultaneous removal of phosphorus and Sulfur from hot metal. The effects of Na2O and oxygen blowing were also studied. The experiments were performed using an induction furnace and hot metal produced in Isfahan Steel Company in the temperature range 1350-1450 ºC...

متن کاملNitrogen adsorption and desorption at iron pyrite FeS2{100} surfaces.
We have investigated the interaction of nitrogen with single-crystal iron pyrite FeS(2){100} surfaces in ultra-high vacuum. N(2) adsorbs molecularly at low temperatures, desorbing at 130 K, but does not adsorb dissociatively even at pressures up to 1 bar. Atomic surface N can, however, be obtained with nitrogen ions and/or excited neutral species, generated by passing N(2) through an ion gun. S...
متن کاملAdsorption and Desorption of Phosphorus and Nitrogen by Immersed Stalks
Adsorption and desorption of phosphorus (P) and nitrogen (N) by stalk residues may influence the concentrations of P and N in runoff. A laboratory study was conducted to measure the effects of P and N constituents in solution on adsorption and desorption of P and N by corn, soybean, and wheat stalk residues. Experimental variables included type of stalk material (corn, soybean, and wheat), inor...
متن کاملEvaluation of Nitrogen Diffusion in Plasma Nitrided Iron by Various
Diffusion of nitrogen in plasma nitrided iron and structural evolution during the nitriding process were evaluated by several characterization techniques including optical microscopy (OM), microhardness depth profiling (HDP), scanning electron microscopy (SEM), x-ray diffraction (XRD), glow discharge optical emission spectroscopy (GDOES), and secondary ion mass spectroscopy (SIMS). Plasma ni...
