Abstract of the dataset | Low sulphur content is essential for high-quality steels and can be achieved by using desulphurization slag. During the desulphurization process the chemical composition of the slag changes leading to alteration in its thermophysical properties, such as surface tension, viscosity, and density. However, the influence of CaS on these thermophysical properties is poorly investigated nowadays. In this study, the influence of various CaS content (0-10 wt%) and CaO/Al2O3 ratio (1.87-1.36) on the viscosity, surface tension, and density of desulphurization slags is investigated. Measurements of surface tension and density are carried out using the maximum bubble pressure method, while viscosity is determined using the rotating bob method. The obtained results show that a decrease in viscosity value is observed with an increase in CaS content only up to 6 wt%, however, further addition of CaS sharply increases viscosity. In case of surface tension and density measurements, an increase in CaS content up to 10 wt% results in a reduction of both property values. Additionally, to study microstructure differences of the investigated slags, they were quenched and examined using Scanning electron microscopy (SEM) and Energy-dispersive X-ray spectroscopy (EDX). | |

Project abstract | The focus of the doctoral research project P5 within the research training group GRK2802 was to determine the influence of CaS on the thermophysical properties of slag, such as density, surface tension, and viscosity, as well as their influence on the interaction with MgO-C refractory materials. The MgO-C refractories were supplied by the industrial partner, Refratechnik Steel GmbH The research concentrated on three grades of MgO-C bricks: 1) withouth MgO-C recyclate and with phenolic binder; 2) with 47.5 wt.% MgO-C recyclate and phenolic binder; 3) with 47.5 wt.% MgO-C recyclate and environmentally friendly binder | |
