As part of its blast furnace (BF) and basic oxygen furnace (BOF) upgrade programme, NLMK Lipetsk will reduce its environmental footprint and boost equipment productivity.

The next stage of NLMK Lipetsk aspiration system upgrade will involve the installation of an advanced dedusting system at its 2.1 m t blast furnace that is currently being overhauled. The filtered materials will be used in production.

In line with the company’s long-term environmental programme, the last of its six BOFs will be upgraded and equipped with a new dust and gas collecting system that complies with the best cleaning technologies and captures 99.9% of dust. Captured BOF gas will be utilized to generate electricity at NLMK’s new co-generation plant.

BOF productivity will increase from 7,600 to 8,900 t of steel per day (+17%).

Works are scheduled for completion in Q4 2020. A total of 24,000 t of equipment and steel structures will be installed for the two projects.

Total investment in the BF and BOF upgrade projects will amount to RUB 36 billion.
