Application of Shotcreting for Restoring the Working Layer of PAO MMK Oxygen-Converter Workshop Steel-Pouring Ladle Lining

A method for shotcreting steel-pouring ladles under PAO MMK oxygen-converter workshop (OCW) conditions is described. Tests are conducted in the period 2018 – 2020. Results of the work performed are identification of operating parameters that affect wear of the working layer of the lining of steel-pouring ladles beneath the shotcrete layer, prospects for maintaining the lining by shotcreting in order to reduce lining working layer wear and as a result increase the life of PAO MMK OCW steel-pouring ladles.
