Ukrainian miner and steel producer Metinvest Group has stated that it will invest around $1 billion in revamping of blast furnace # 4 at its subsidiary Azovstal Iron and Steel Works. 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.
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 tons of iron.
Repair activities directly on iron-melting facility will be launched in June. Just then blast furnace will be shutdown.
