Vertical, inclined and suspended shields of vessel #1 were also refurbished, the drive was repaired, in-house rails were laid down, and the waste heat boiler was repaired. 

BOF vessel #1 approached its maintenance period with a record-high lining campaign life of 5,045 heats, which is 68% higher than the producer's warranty. This was achieved through the application of extraordinary solutions within BOF steel making technology. Using high quality refractory lining Azovstal specialists plan to set new records.

- We enhance our cooperation with other enterprises of the Metinvest Group trying to use as less of third party services as possible. By doing so, we reduce our maintenance costs without detriment to quality. Using refractory materials from Zaporozhye Azovstal was able to save c. USD 700,000, and our new partner was able to get a reliable client during the difficult period for the Ukrainian economy.
