The paper addresses the urgent issue of extending the operational life of critical steelmaking equipment — the main column of a Continuous Casting Machine (CCM) ladle turret. Based on the actual technical documentation of Primetals Technologies for the Voestalpine plant, a study of the column's stress-strain state during its restoration to repair dimensions was performed. Particular attention is paid to the specifics of the unit's operation as a damping device subjected to cyclic loads during the lifting and lowering of steel ladles. The feasibility of using column re-machining instead of manufacturing a new expensive product is justified, which provides a significant economic effect while maintaining normative fatigue strength reserves.
