Abstract of the dataset | Given the growing emphasis on refractory recycling, the performance characteristics of commercial MgO-C bricks incorporating MgO-C recyclates are of considerable economic and environmental relevance. In the present study, four-point bending tests are conducted in an argon atmosphere on three commercial MgO-C brick grades over a temperature range from room temperature to 1300 °C. One MgO-C brick grade is produced exclusively from virgin raw materials, whereas the other two grades incorporate MgO-C recyclate at a high mass fraction of 47.5 wt.%. Due to the different sources of the recyclates, their carbon contents vary, resulting in different total carbon contents in the two MgO-C brick grades containing recyclate. Post-mortem SEM investigations show predominantly transgranular fracture through the MgO-C recyclates. The evaluation of the four-point bending tests reveals no detrimental effect of the MgO-C recyclates on bending strength. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents correlating with higher bending strength values. Furthermore, the heterogeneous structure of the MgO-C recyclates contributes to enhanced stress dissipation caused by anelastic deformation processes in the respective MgO-C brick grades, despite the accompanying decrease in virgin flake graphite content. | |

Project abstract | The focus of the doctoral research project P2 within the research training group GRK2802 was the evaluation of the thermo-mechanical properties of commercial MgO-C bricks, which were supplied by the industrial partner, Refratechnik Steel GmbH. The research concentrated on three grades of MgO-C bricks: while material F was produced exclusively from virgin raw materials, the two materials R contained 47.5 wt.-% MgO-C recyclate, which, however, possessed different carbon contents due to different sources of the recyclates. | |
