The use of ash-mineral mixtures for the construction of high-strength coatings of forest roads
Forest roads are characterized by difficult transport and operating conditions and a considerable distance from sources of traditional road-building materials. Local ash and slag waste of the state district power station is an effective road-building material for the construction of forest roads. The article presents the test results of the buildin...
The effect of gamma radiation on the mechanical and microstructural properties of Fe-rich inorganic polymers
Inorganic Polymers (IPs) are interesting alternative binder materials to Ordinary Portland Cement (OPC). They could be potentially used in applications such as nuclear safety structures and radioactive waste management since they are highly chemically and thermally resistant. However, their chemical and mechanical stability still has to be proven w...
Non-Newtonian behavior of solid-bearing silicate melts: An experimental study
© 2018 Elsevier B.V. The non-Newtonian behavior and its mechanism have not been clarified for the solid-bearing silicate melts, leading to difficulties and even errors in estimating silicate melt viscosity. In this study, a typical metallurgical slag was employed as a model system of solid-bearing silicate melt. The flow behavior of the slag was me...
A Reaction between High Mn-High AI Steel and CaO-SiO2-Type Molten Mold Flux: Reaction Mechanism Change by High Al Conten...
A series of laboratory-scale experiments were carried out in order to elucidate the reaction mechanism between high Mn-high Al steel and CaO-SiO2-type molten mold flux at 1 450 degrees C, which represents the reaction taking place during continuous casting of the steel. Compared to the previous study [Kim etas., Metall. Mater. Trans. 44B (2013) 299...
Quantitative Study on Dissolution Behavior of Nd2O3 in Fluoride Melts
The dissolution of rare earth oxides in molten fluorides is a critical step in the preparation of the corresponding rare earth metals by oxide-fluoride electrolysis. However, quantitatively understanding the nature of dissolution, especially in the case of molten salts, is usually difficult to be achieved by postmortem characterization. In this pap...
Investigation of Reactive Origin for Attachment of Cu Droplets to Solid Particles
Published in Metallurgical and Materials Transactions B
Both primary and secondary copper productions encounter a limitation in the process efficiency due to droplet losses in slags. One of the causes for the mechanical entrainment of these droplets is their interaction with solid spinel particles, hindering the sedimentation of the copper droplets. Previous experiments with synthetic slags provided ins...
Sessile drop evaluation of high temperature copper/spinel and slag/spinel interactions
Metal droplets sticking to spinel solids, present in metallurgical slag systems, play an important role in hindering the sedimentation of copper in slags. To understand this phenomenon, the interaction between spinel particles with Cu on one hand and with slag, on the other hand, was evaluated. A dedicated approach was applied, using an industriall...
Crystallization Behaviors of CaO-SiO2-Al2O3-Na2O-CaF2-(Li2O-B2O3) Mold Fluxes
The effects of basicity (CaO/SiO2), B2O3, and Li2O addition on the crystallization behaviors of lime-silica-based mold fluxes have been investigated by non-isothermal differential scanning calorimetry (DSC), field emission scanning electron microscopy, X-ray diffraction (XRD), and single hot thermocouple technique. It was found that the crystalliza...
