چکیده
The modification of basic oxygen furnace (BOF) slag by adding silica can improve the properties BOF for applications in cement industry. rapid dissolution is essential to hot modification. In this work, behavior molten CaO-SiO2-Fe2O3-MgO-MnO system as synthetic was investigated using traditional rotating cylinder technique. Effects rotation speed, temperature, immersion time, and basicity on were studied. Scanning electron microscopy equipped with energy dispersive spectrometer (SEM-EDS) FactSage simulations employed reveal mechanism. It found that rod affected both thermodynamic driving force viscosity. rate increased increasing speed but first then decreased when decreasing from 2.5 1.5. A linear correlation between logarithm periphery velocity a slope 0.44 observed, indicating mass transfer within boundary layer determining step. direct way during slag.

Slag Behavior in Gasifiers. Part II: Constitutive Modeling of Slag
The viscosity of slag and the thermal conductivity of ash deposits are among two of the most important constitutive parameters that need to be studied. The accurate formulation or representations of the (transport) properties of coal present a special challenge of modeling efforts in computational fluid dynamics applications. Studies have indicated that slag viscosity must be within a certain r...
متن کاملFLOW BEHAVIOR OF MOLTEN METAL IN ALUMINUM LFC PROCESS
The effects of gating system and pattern geometry on the metal flow in the lost foam casting (LFC) process have been investigated using glass covered mold and video recording system. Unlike convectional casting process, the type of the gating system showed little effect on fillability in lost foam, but pattern thickness had large effect on mold filling. The mold filling behavior seems to be con...
متن کاملEFFECT OF A CHLORIDE FLUX ON THE DISSOLUTION OF Mn-Al COMPACTS IN MOLTEN ALUMINUM
Abstract: Dissolution and recovery of Mn-Al compacts with and without a chloride flux was studied by taking samples from the melt after addition of the compact. Events occurring after the addition of the compacts into the melt were studied using water quenched specimens after holding them for a specified time in molten state. The cross sections of these specimens were characterized by SEM a...

As innovative means to recover actinides from irradiated fuels, pyrochemical processes are proposed. In the Japan Atomic Energy Research Institute (JAERI), the feasibility of applying molten-salts processes to nitride fuels containing transuranium elements for transmutation is investigated. In the course of study, experiments and analyses have been made on the high-temperature chemistry of M–N–...
متن کاملA Study of the Influence of Slag Alkali Level on the Alkali-Silica Reactivity of Slag Concrete
Ground granulated blast furnace slag (ggbs), can reduce the alkali load in concrete, despite its relatively high alkali content. Most research has been devoted to the efficacy of slag with an alkali content of less than 1.0% and this is reflected in guidance documents. A comparative assessment was made of the effect, if any, of the alkali level of ggbs on potential alkali-silica reactivity. Exp...
