Metinvest Group continues modernization of the blast furnace process at Azovstal pursuant to its Technological Strategy-2030. Blast Furnace No. 6 was shut down for a major overhaul. Modernization of the blast furnace will increase its energy efficiency, decrease production costs and reduce dust emissions by 55%.

Shut down of Blast Furnace No. 6 progressed pursuant to the developed technological operations. Currently, the cool down process of the furnace completed. Preparatory works for the structures dismantling and major overhaul are in progress.

In the course of the overhaul of Blast Furnace No. 6 at Azovstal Iron and Steel Works, the modernization of the charging system and stockhouse, reconstruction of the casthouse and furnace itself will be carried out, a new cooling system with copper coolers, a new lining and a bell-less top charging system will be installed.

Also, preparations are in progress for the construction of a slag granulation and the connection to the pulverized fuel injection (PCI) plant. Currently, the slag granulation located near the blast furnace is considered the most rational type of processing, because it excludes of the fleet of slag ladles from the operation, significantly simplifies the logistics, reduces the cost of production and burden on the environment.

Major overhaul of Blast Furnace No. 6 continues the series of the phased modernization of the blast furnace capacity at Azovstal. The blast furnaces are being upgraded one by one based on the European environmental requirements with the transition to the closed-loop cooling system”.
