In developed countries, nearly half of steelmaking slag is reused in road construction. Determining free lime content important because the hydration can result fracturing. Recently, we have a simple method to rapidly determine area fraction via cathodoluminescence (CL) imaging based on orange illuminated areas corresponding lime. However, that precipitated along grain boundaries wüstite were o...

During carbon steel manufacture, slag residues are generated to remove material impurities from liquid metal and thus control the quality of carbon steel. As the utilization of secondary metallurgical slags is not as efficient as those of primary slags, a comprehensive characterization of steel ladle slag was performed. Pseudo-total concentrations of a wide range of elements were determined dur...

The elimination of inclusions in steelmaking processes has been widely studied. removal by slags containing the rare earth oxide Ce2O3 are studied using an integrated numerical model. model involves inclusion motion model, interfacial tension calculation surface slag, and mass action concentration based on ion molecule coexistence theory. behaviors both solid Al2O3 50%wtAl2O3–50%wtCaO liquid va...

in this study, slag penetration into a magnesia refractory monolithic was investigated by the crucible test method. a synthetic calcium aluminate slag system has been used to study commercial magnesia mix refractory for 1, 2, 3, 4, 5 and 6 hours at 1450°c and 1600°c. it has been shown that the penetration rate is controlled by a diffusion mechanism at 1450°c. in this case, capillaries are the ...
