Abstract of the dataset | Abstract In the present study, the surface tension of sulfur-containing manganeseboron steels is measured at high temperatures via the Maximum Bubble Pressure (MBP) method. Density, essential for determining surface tension, was measured in parallel and found to decrease slightly with rising temperatures, from 6952 ± 13 to 6830 ± 85 kg m−3 between 1550 and 1650 °C, as seen in the alloy containing 130 ppm S. Surface tension in this alloy increased from 1234 ± 4 to 1301 ± 9 mN m−1 as the temperature increased from 1550 to 1650 °C, with a consistent positive temperature coefficient. Even small additions of sulfur significantly reduced surface tension at all temperatures. For instance, at 1600 °C, the surface tension decreased from 1389 to 1264 mN m−1 with the increase of sulfur from 39 to 130 ppm. The relationship between surface tension and sulfur content followed an inverse logarithmic relationship and the temperature increase decreased the coefficient of change of the surface tension. This work generated reliable results, contributing to the understanding of surface tension and providing data for the processing of this steel grade. | |

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. | |
