Abstract of the dataset | This study explores the thermophysical properties and crystallization behavior of two in-dustrial Mold Fluxes (MF1 and MF2) used in continuous steel casting. Viscosity, density, and surface tension were measured using the Rotating Bob Viscometry (RBV) and the Maximum Bubble Pressure (MBP) method, while crystallization dynamics were assessed via the Single Hot Thermocouple Technique (SHTT). Both fluxes showed tempera-ture-dependent viscosity with distinct break temperatures influenced by chemical compo-sition. MF1 had higher viscosity and activation energy (127.72 kJ mol−1) than MF2 (112.11 kJ mol−1) due to its higher Al2O3 content. Density and surface tension decreased linearly from 1523 to 1623 K, with values of 2642–2618 kg m−3 and 299–291 mN m−1 for MF1, and 2708–2656 kg m−3 and 348–305 mN m−1 for MF2. Crystallization analysis showed that MF1 required higher cooling rates (critical cooling rates: 21 K s−1 vs. 18 K s−1 for MF2) for glass formation, highlighting its greater glass-former content. | |

Project abstract | The focus of this project is to investigate the interaction of a Al-killed low-sulphur manganese-boron steel and a highly basic desulphurisation slag with MgO-C products based on recyclates and environmentally friendly binders. In order to determine the influence of thermophysical properties on the interaction with new refractory materials, the viscosity, surface tension and density of the liquid aluminium-killed steel in undesulphurised and desulphurised condition and the slags with high sulphur capacity are investigated as a function of [S], [B], (SiO2), (MgO), (S) and temperature. By finger testing a MgO-C product in the molten steel and slag, the refractory samples are obtained for further analysis of the interactions using optical microscopy and SEM/EDX. The (S)/[S] distribution between the MBW1500 steel and the slag is investigated in a crucible of MgO-C products based on recyclates in the MFG-40. The inclusion population of the steel samples after examination via Finger Testing is interpreted by chemical analysis and analysed by optical examination methods such as light microscopy combined with AFA (Automatic Feature Analysis) in P-SEM. The spinel formation between recycled MgO-C material and liquid steel is specifically studied in SEM/EDX microscopy. | |
