Examination of industrial safety of structures of the continuous casting Department of the open-hearth shop of the Taganrog Metallurgical Plant

The working draft of the main building of the department of continuous casting of billets (ONLZ) of the open-hearth shop of JSC Tagmet at the stage of "KM" was developed by the DKO of JSC UkrNIIPSK in 2000. Taking into account the design decisions taken and the need to ensure high reliability of structures arising from the specifics of metallurgical production (when installing a heavy duty crane (7K) with a lifting capacity of 225+63/20t at a significant height of the crane rail head – 27 m) in 2001, the customer (JSC Tagmet) decided to carry out an expert examination of design solutions for the main structures of the building frame and engaged the Central Research Institute of Building Structures named after V.A. Kucherenko, who, since 1995, has already conducted surveys of other workshops of the plant, built back in the XIX century, for this work. Then the correctness of the choice of sections and lengths of the elements of the main load-bearing structures was checked and the load-bearing capacity of these elements was assessed. The forces in the elements obtained as a result of carrying out a verification calculation on a computer with the refinement of the design scheme, the applied loads and the quality of steel used in the elements were used. The article presents the reasons for the conduct and results of the industrial safety examination carried out in 2011, a new department was put into operation by 2005, attached to the open-hearth shop.
