Experimental Study on the Behavior of TiN and Ti2O3 Inclusions in Contact with CaO‐Al2O3‐SiO2‐MgO Slags
TiN and Ti2O3 are the predominant inclusion types in Ti-alloyed ferritic chromium stainless steels. In order to ensure the required steel cleanness level, an effective removal of such inclusions in the slag during secondary metallurgy is essential. This inclusion removal predominantly takes place via dissolution of the inclusion in the slag. The dissolution behavior of TiN and Ti2O3 in CaO-SiO2...
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 کاملdesulfurization 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 کاملRECYCLING PRACTICES OF SPENT MgO-C REFRACTORIES
The recycling options of spent MgO-C refractories from an electrical arc furnace (EAF) have been evaluated. The economic, quality of spent refractories and products made from it, the ease of implementation of a recycling practice and the interest of steel melt shops were considered. It was decided that the best option of most EAF shops would be to recycle spent MgO-C refractory as a foaming sla...
متن کاملMelting Behaviour of Model Lherzolite in the System CaO–MgO–Al2O3–SiO2–FeO at 0·7–2·8 GPa
Fe–Mg exchange is the most important solid solution involved in for Fe–Mg exchange between the coexisting crystalline phases and melt, KdFe–Mg, show a relatively simple and predictable behaviour partial melting of spinel lherzolite, and the system CaO– MgO–Al2O3–SiO2–FeO (CMASF) is ideally suited to explore with pressure and temperature: the coefficients for olivine and spinel do not show signi...
