Abstract of the dataset | This study investigates the thermophysical properties of low-sulphur manganese-boron steel with varying boron and sulphur contents at different temperatures. Density and surface tension were measured between 1550-1650 °C using the Maximum Bubble Pressure (MBP) method, while viscosity was examined between 1530-1570 °C using an improved Oscillating Crucible Viscometer (OCV). The methods yielded results with low error, consistent with existing literature. The density of the base steel decreased from 7057 ± 25 kg m-3 at 1550 °C to 6843 ± 85 kg m-3 at 1650 °C. The addition of boron (up to 57 ppm) and sulphur (up to 130 ppm) did not significantly change the density. Sulphur, increasing from 39 ppm to 130 ppm, reduced the surface tension from 1416 ± 12 mN m-1 to 1302 ± 9 mN m-1 at 1650 °C. Boron’s effect on surface tension varied, possibly influenced by other elements like oxygen. Viscosity ranged from 5.74 to 6.44 mPa s, with boron and sulphur additions causing minimal changes, the largest deviation being 8%. These results provide valuable data for the simulation, modelling, control, and optimization of liquid steel processing. | |

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. | |
