desulfurization of plain carbon steel by cao-al2o3-sio2 and cao-al2o3-sio2-x (x = na2o, sro) synthetic slags
synthetic slag process decreases sulfur and phosphorus contents of steel, improves inclusion removal, protects steel from atmosphere and prevents temperature drop of the liquid steel in the ladle. in this study, the synthetic slags of ternary cao-al2o3-sio2,and quaternary cao-al2o3-sio2-na2o and cao-al2o3-sio2-sro systems were pre-melted and then were kept in contact with the liquid steel in a ...
متن کاملElectronic/Ionic Properties of FexO–SiO2–CaO–Al2O3 Slags at Various Oxygen Potentials and Temperatures
Electrochemical nature of metallurgical reaction arouses more and more attentions, and the most closely related is the electrical conductivity of molten slag. The electrical conductivity of molten slag is not only an important physical property that plays a prominent role in modeling and operating the electric smelting furnace and optimizing the metallurgical process, but also important for und...
متن کاملTie-Lines and Mixing Properties of Solid Solutions in the System CaO-SrO-PbO-O at 1100 K
Phase relations in the system CaO-SrO-PbO-O2 at 1100 K have been determined by equilibrating samples with different compositions in air, oxygen, or evacuated ampoules for 7 days and characterizing quenched specimens by optical and scanning electron microscopy, energy-dispersive analysis of x-rays (EDX), and x-ray diffraction (XRD). There is a solid-state miscibility gap in the pseudo-binary sys...
متن کاملEffective role of CaO/P2O5 ratio on SiO2-CaO-P2O5 glass system
In the present work, the effect of the CaO/P2O5 ratio on the composition of sol-gel synthesized 58SiO2-(19 - x)P2O5-(23 + x)CaO (x = 0, 5, 10 and 15 mol%) glass samples was studied. Further, the effect of NBO/BO ratio on hydroxy carbonated apatite layer (HCA) forming ability based on dissolution behavior in simulated body fluid (SBF) solution was also investigated. CaO/P2O5 ratios of synthesize...
متن کاملPetedunnite (CaZnSi2O6): Stability and phase relations in the system CaO-ZnO-SiO2
The phase relations of petedunnite [CaZnSi2O6 (pd)] were determined experimentally at P-T conditions up to 2.5 GPa and 1100 °C. Single-phase petedunnite is formed at high pressures (P > 0.8 GPa). Reversed experiments show that at lower pressures and temperatures >650 °C petedunnite decomposes to willemite [Zn2SiO4 (wil)], hardystonite [Ca2ZnSi2O7 (har)], and quartz [SiO2 (qtz)] according to the...
