The main causes for formation of cracks and local sagging in cast large-sized case structures used in metallurgy are considered. Modeling of stress-strain state of the most loaded zones of slag carrier bowls in operation was performed. It is shown that to reduce residual deformations of cast bowls, it is necessary to apply additional stiffeners in the form of welded-on ribs. Calculation was used to determine the required parameters of stiffeners and welds. 7 Ref., 8 Figures.
