Abstract of the dataset | In light of the increasing focus on the recycling of refractories, the properties of commercial MgO-C refractory bricks containing MgO-C recyclate are of significant economic and ecological importance. In the present study, MgO-C recyclate and two commercially available MgO-C bricks – one grade consisting exclusively of fresh raw materials while the other containing 47.5 wt.% MgO-C recyclate – were comprehensively characterized. This involved the use of X-ray computed tomography, scanning electron microscopy, X ray fluorescence analysis, X-ray diffraction, as well as density and porosity measurements. The MgO C recyclate exhibited a heterogeneous composition consisting of MgO aggregates and contained an increased content of impurities compared to fresh MgO raw materials. The incorporation of MgO C recyclate as a raw material for commercial MgO-C bricks resulted in a decrease of the average MgO aggregate size, a higher porosity with a decrease in the median pore size and a reduced CaO/SiO2 ratio of the corresponding MgO-C brick grade. Furthermore, the MgO-C grade with 47.5 wt.% MgO-C recyclate exhibited a higher cold crushing strength, but a reduced oxidation resistance. | |

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. | |
