Abstract (en)
[origin: EP4113044A1] The present technical solution, in general, relates to the field of metallurgy, more particularly to technologies for lining metallurgical units and other thermal units by the shotcrete method and to the realization thereof in apparatus terms. The method for lining metallurgical units comprises cleaning the surface to be lined with shotcrete concrete of contaminating elements; mixing the shotcrete concrete with water using equipment for preparing a concrete mix; directing the concrete mix produced in the previous step to a concrete pump and then, via a pipeline, further to the work site where the mix is applied on the lining, wherein a nozzle for applying the concrete mix is fitted at the end of the pipeline; applying the concrete mix on the prepared surface for lining with shotcrete concrete by mixing the concrete mix with a hardener at the nozzle. The technical result consists in reduced consumption of refractory materials used for lining the working layer of walls of metallurgical units.
