Siemens VAI signed a several hundred million euro contract with Zaporizhstal for new steel mill10/01/2008 | Zaporizhstal Integrated Iron & Steel Works JSC (Zaporizhstal JSC) has awarded Siemens VAI Metals Technologies a several hundred million euro contract to provide a range of equipments for its new steel mill. Precontractual works were performed by Siemens Ukraine specialists in Donetsk. The new metallurgical complex will be capable of producing 4.7 million tons of carbon steel grades per year for a wide range of industrial applications. Following start-up of the oxygen steelmaking facilities scheduled to begin in late 2010, Zaporizhstal JSC will eventually terminate its open-hearth-steelmaking production and ingot-casting route, resulting in significant cost savings, product quality and environmental advantages. |
Siemens VAI will provide basic engineering for the steel bay and plant layout in addition to detailed engineering and the supply of key process equipment. This includes two hot-metal desulphurization stations, two 250-ton-capacity LD (BOF) oxygen steelmaking converters, two twin-station ladle furnaces, a VOD (vacuum oxygen decarburization) plant, two 2-strand slab casters, primary and secondary dedusting facilities and the related electrical and Level 1 and Level 2 automation systems. For this project Siemens VAI will also supply two hot-metal ladle-transport lines, twelve 300-ton torpedo cars for transporting hot metal, ladles, a laboratory, and various auxiliary facilities and spare parts. Siemens VAI will provide a broad range of technological packages to optimize production performance, casting flexibility and product quality. These include LevCon automatic mold-level control with fully automatic start of casting operations, MoldExpert for strand-break-out prevention, DynaWidth for the automatic adjustment of the slab width during casting and DynaFlex for the on-line adjustment of the mold-oscillation parameters. Furthermore, SmartSegments will be installed for the remote adjustment of the roller gap settings for casting different slab thicknesses, which, in combination with DynaGap SoftReduction technology, will compress the slab thickness in the area of final strand solidification to improve the internal slab quality. Level 2 process models include the Dynacs secondary cooling model, YieldExpert for optimization of the cut-slab length as well a VAIQ slab-quality control. Advisory services for erection, start-up and commissioning as well as training round off the Siemens VAI scope of supply. |
