| 1 | Oxide Inclusions at Different Steps of Steel Production显示文摘The formation of oxide inclusions in one of the carbon steel productions of Mobarakeh Steel Complex of Isfahan has been evaluated. Several samples from different steps of steel production were taken, from arc furnace, ladle furnace, tundish, and continuous casting mold. Moreover, samples of slab and hot rolling products were prepared. The samples were investigated by optical and scanning electron microscopes equipped with the EDS system. According to the results, the number, composition, and kind of inclusions were directly influenced by the production variables. It was found that when the amount of dissolved oxygen was high (say more than 0.002 5%), the dissolved aluminum was able to reduce silicon oxide and react with the dissolved oxygen simultaneously, whilst, the dissolved aluminum could reduce the magnesium oxide only when the oxygen content was below 0.000 5%. Based on this research, a mechanism for forming the complex inclusions was suggested. It was also found that if the aluminum is added to the melt as late as possible, a cleaner melt with fewer inclusions is prepared; this method will be more effective, especially in the case of complex inclusions. | Yousef Payandeh Mansour Soltanieh | 2007 | Journal of Iron and Steel Research(International)2007，14，5： | 10 |
| 2 | Rapid high-temperature synthesis of SAPO-34 nanoparticles显示文摘Decreasing particle size results in larger increase of external surface area and shorter diffusion path,both reducing mass and heat transfer resistances in catalysis and sorption.A rapid high-temperature hydrothermal synthesis method was developed to synthesize uniform nanoparticles of SAPO-34 zeolite with high crystallinity.To investigate the effects of temperature and synthesis time on purity and crys-tallinity of the final products,the crystallization temperature was increased from 468 to 673 K while the synthesis time was decreased from 24 h to 45 min.The products were characterized by XRD and SEM techniques.It was found that high temperature and short synthesis time reduce the particle size and change the morphology of the SAPO-34 final product. | Mahdi Dargahi Hossein Kazemian Mohammad Soltanieh Sohrab Rohani Morteza Hosseinpour | 2011 | Particuology2011，9，5： | 7 |
| 3 | Relationship between Oxygen Chemical Potential and Steel Cleanliness显示文摘To investigate inclusion formation in each step during steel making process, several samples were taken in different steps of the production of steel at Mobarakeh Steel Co of Esfahan to measure the oxygen chemical potential of the molten steel in each stage. The chemical compositions of the inclusions in samples were investigated by scanning electron microscope. The chemical composition of the slag was analyzed. With the use of thermodynamic calculations and chemical analysis of the melt, at the working temperature, the relationship between dissolved oxygen and other elements were determined. Finally, it was found that there is a close relationship between inclusions formed in each step with the oxygen partial pressure. | Mansour Soltanieh Yousef Payandeh | 2005 | Journal of Iron and Steel Research(International)2005，12，5： | 3 |

| 15 | Diffusion mechanism in molten salt baths during the production of carbide coatings via thermal reactive diffusion显示文摘The diffusion mechanism of carbide-forming elements from a molten salt bath to a substrate surface was studied in this research, with particular focus on the processes occurring in the molten bath at the time of coating. Metal, oxide, and metal-oxide baths were investigated, and the coating process was performed on H13 steel substrates. Scanning electron microscopy and electron-probe microanalysis were used to study the coated samples and the quenched salt bath. The thickness of the carbide coating layer was 6.5 ± 0.5, 5.2 ± 0.5, or 5.7 ± 0.5 μm depending on whether it was deposited in a metal, oxide, or metal-oxide bath, respectively. The phase distribution of vanadium-rich regions was 63%, 57%, and 74% of the total coating deposited in metal, oxide, and metal-oxide baths, respectively. The results obtained using the metal bath indicated that undissolved suspended metal particles deposited onto the substrate surface. Then, carbon subsequently diffused to the substrate surface and reacted with the metal particles to form the carbides. In the oxide bath, oxide powders dissolved in the bath with or without binding to the oxidative structure(Na_2O) of borax; they were then reduced by aluminum and converted into metal particles. We concluded that, in the metal and oxide baths, the deposition of metal particles onto the sample surface is an important step in the formation of the coating. | Aliakbar Ghadi Hassan Saghafian Mansour Soltanieh Zhi-gang Yang | 2017 | International Journal of Minerals,Metallurgy and Materials2017，24，12： | 1 |
