The companies' commitment to zero CO2 emissions by 2050 has promoted a huge effort in the search for alternatives to replace conventional products, in order to drastically reduce the carbon footprint. In refractory industry, for example, materials produced at low temperatures have been researched to replace high temperatures fired bricks, with significant CO2 emissions in their processing. This is the case of MgO-Cr2O3 products, used in RH degassers. In addition to the environmental appeal for CO2 reduction, the elimination of chromium is also a pursued objective, mainly due to the possibility of contamination of the environment by Cr+6. Additionally, new possibilities for safe recycling can be explored with the absence of chromium. This work presents the efforts in the development of baked Cr-free alternative refractories for application in RH degassers, to contribute with environmentally friendly products for a better world.
