During reconstruction of Blast Furnace No.3, they will apply a method of SKD (semi knocked down) assembly by means of the crane made by Mammoet Company with lifting capacity of 1600 t. The first time in Ukraine, while realization of huge infrastructural projects, Zaporizhstal Works applied the best world practice – it created an intellectual model of the blast furnace, which should increase the reconstruction effectiveness and cut back its performance terms. The intellectual 3D-model of blast furnace at the stage of scheduling, allowed to find and eliminate over 11 thousand errors.
The reconstructed Blast Furnace No.3 of PJSC «Zaporizhstal» will be equipped with the state-of-the-art aspiration system with devices of continuous automatic control that meets the strictest European requirements. Besides, within the project, they will install a new belles top charging system made by Danieli Corus Company, they increased from 16 to 20 of tuyeres and a combined lining has been made applying the state-of-the-art technologies. Besides, at BF No.3, they will replace the scale capsules for the charge-conveyor system, the furnace cooling system will be equipped with copper cooling plates.
For the last five years, PJSC «Zaporizhstal» invested in ecological production modernization UAH 5.6 billion of own funds. The major projects made for that period are – a new sintering machine No.1 with high-efficient gas cleaning system, erection of gas cleaning systems at sintering machines Nos. 2 to 6, a large-scale modernization of Blast Furnace No.4 with installation of the aspiration system at the cast house and stock house trestle, overhaul repair of Blast Furnace No.2 with erection of the new aspiration system at the cast house and construction of a new Continuous Pickling Line (CPL-4) at the Cold Rolling Mill Shop.
