چکیده
To understand the reaction mechanism between high Mn-high Al steel and slag, experiment of Fe-Mn-Al melts with CaO-SiO2-type flux was carried out in MgO crucible at 1873 K. The evolution morphology interface inspected firstly, then global kinetics modeled consideration effect dynamic interfacial phenomena. results show that Fe-5 mass % alloy SiO2 or low protective strong chemical affinity metal leads to spontaneous emulsification attenuated progression reaction. Combined change area caused by emulsification, it is found can be described satisfactorily transfer model liquid steel, determined coefficient about k[Al]=4.46×10−5 m/s. However, phenomenon Fe-13%Mn-5%Al slag did not disappear reaction, which attributed decreasing tension Mn addition accumulation C on interface. This process assuming as rate-controlling step estimated k(SiO2)=5.12×10−6

Relationship between Molten Oxide Structure and Thermal Conductivity in the CaO–SiO2–B2O3 System
Using a transient hot-wire method, the thermal conductivity of the CaO–SiO2–B2O3 mold flux system was measured. The effects of temperature, BO1.5 concentration and basicity on the thermal conductivity were considered, along with structural investigation by Raman spectroscopy. It was found that the addition of boron oxide caused both a decrement and increment of thermal conductivity, depending o...
متن کاملStructural properties of molten silicates from ab initio molecular-dynamics simulations: comparison between CaO-Al2O3-SiO2 and SiO2
We present the results of first-principles molecular-dynamics simulations of molten silicates, based on the density functional formalism. In particular, the structural properties of a calcium aluminosilicate [ CaO-Al2O3-SiO2 ] melt are compared to those of a silica melt. The local structures of the two melts are in good agreement with the experimental understanding of these systems. In the calc...

Interfacial Reaction Kinetics
We study A-B reaction kinetics at a fixed interface separating two immiscible bulk phases, A and B. Coupled equations are derived for the hierarchy of many-body correlation functions. Postulating physically motivated bounds, closed equations result without the need for ad hoc decoupling approximations. We consider general dynamical exponent z, where xt ∼ t is the rms diffusion distance after ti...
