Metinvest starts revamping of BF 5 at Azovstal.

Metinvest Group announced that it will invest around USD 1 billion USD in revamping of blast furnace No. 4 at PJSC 'AZOVSTAL IRON & STEEL WORKS' and that on 15 May, the first upgrading and revamping activities were launched at the furnace.

Following revamping the blast furnace will meet the highest international environmental safety standards. Achievement of ambitious emission limit - up to 30 mg per air cubic meter - is in the planning stage. Dust emission into atmosphere will be reduced by 340 tons per annum.

Over the course of revamping activities cast house aspiration system will be dramatically changed; new bag filters with impulse regeneration will be assembled instead of the existing electrostatic precipitators. Nowadays it is the most innovative and efficient type of gas treatment units. Powerful degassing and dedusting system will be installed in the emission generation points, as well as iron runners and slag troughs will be covered. This will provide appreciable ecological effect.

The revamping will extend BF-4 operation period by 15 years more, iron melting time will be reduced and annual production in the long term will be increased up to 1.5 million tonnes of iron.
