The turbulent flow in the mold region drastically influences the quality of steel produced during continuous casting. The flow itself can lead to surface defects or slag entrainment based on the formation. A high surface wave can lead to fluctuations

This work addresses conflicting results in the literature regarding liquid inclusion agglomeration. To assess whether liquid calcium aluminates do agglomerate in liquid steel, laboratory experiments were performed: melting electrolytic iron, deoxidiz

Because of interfacial and surface tension, micron-sized liquid oxide droplets are expected to change from spherical (when fully immersed in liquid steel) to lens shape on top of steel. Inclusion sizes were measured by automated analysis of polished

We demonstrate that Plasma Dual Beam focused ion beam (PFIB) milling can be used for high-resolution three-dimensional chemical study of a single non-metallic inclusion in steel. A CaO-Al2O3-MgO inclusion (~ 10 μm) on a polished cross-section of ste

Spent coffee grounds (SCG), a residue from the soluble coffee industry, was evaluated as an adsorbent for the removal of methylene blue (MB) from aqueous solution. Batch adsorption tests were performed at 25 °C and the effects of contact time, adsor
