NLMK Launches Upgraded Blast Furnace No 6

Release time：Nov 07, 2019 From：admin

NLMK Lipetsk has re launched Blast Furnace No 6 following a large-scale upgrade. As a result, the maximum output of the furnace increased by 8% to 3.4 million tonnes of hot metal per year. A new air treatment system captures 99.9% of dust particles, keeping residual dust content at the level of best available techniques of 5 mg/m3. All of the blast furnace gas formed as a by-product in the manufacturing of pig iron is used for energy generation at NLMK’s cogeneration plant, while blast furnace slag is processed into construction materials. The total CAPEX for the project amounted to over RUB 35 billion.

The furnace is equipped with an advanced automated control system with built-in artificial intelligence components. The system is able to autonomously select optimal process parametres, boosting blast furnace performance.

Blast Furnace No 6 was built in 1978, and is now the second most productive blast furnace at NLMK. In addition to BF 6, NLMK Lipetsk operates four other blast furnaces: BF-3 (1.6 million tonnes), BF-4 (2 million tonnes), BF-5 (2.9 million tonnes) and BF-7 (4.2 million tonnes).
