PJSC «Zaporizhstal» has shut down Blast Furnace No.3 for a large-scale reconstruction, which is planned to be performed within 150 days. Investments in this project will amount to about UAH 1.5 billion.
During the reconstruction of Blast Furnace No.3, a method of SKD (semi knocked down) assembly will be applied. This will be facilitated by a crane made by Mammoet Company, with a lifting capacity of 1600 t. For the first time in Ukraine, while realizing huge infrastructural projects, Zaporizhstal Works has applied the best world practices by creating an intellectual model of the blast furnace. This model is expected to increase reconstruction effectiveness and reduce performance timelines. The intellectual 3D-model of the blast furnace, at the scheduling stage, allowed for the identification and elimination of over 11 thousand errors.
The reconstructed Blast Furnace No.3 of PJSC «Zaporizhstal» will be equipped with a state-of-the-art aspiration system, featuring devices for continuous automatic control that meet the strictest European requirements. Furthermore, within the project, a new belles top charging system will be installed, made by Danieli Corus Company, which has increased the number of tuyeres from 16 to 20. Additionally, a combined lining will be constructed using advanced technologies. The scale capsules for the charge-conveyor system will be replaced, and the furnace cooling system will be equipped with copper cooling plates.
Over the past five years, PJSC «Zaporizhstal» has invested UAH 5.6 billion of its own funds into ecological production modernization. The major projects undertaken during this period include a new sintering machine No.1 with a high-efficient gas cleaning system, the erection of gas cleaning systems at sintering machines Nos. 2 to 6, a large-scale modernization of Blast Furnace No.4 with the installation of an aspiration system at the cast house and stock house trestle, as well as an overhaul repair of Blast Furnace No.2 with the erection of a new aspiration system at the cast house and the construction of a new Continuous Pickling Line (CPL-4) at the Cold Rolling Mill Shop.
