NLMK improves environmental friendliness of blast furnace production

Press Releases

Novolipetsk Metallurgical Plant has completed the modernization of blast furnace No. 4 with a capacity of 2.1 million tons of pig iron per year.

The project includes environmental modernization of the furnace infrastructure. All dust generated in the metal production process will be captured by a highly efficient gas cleaning system. The purification rate will be 99.9%, which is in line with the best available technology. The new equipment will also provide more efficient cleaning of blast furnace gas for use as a secondary energy resource. Filtered dust will be sent to the production of iron briquettes and returned to the blast furnace process.

In the course of the project, the furnace was equipped with a new lining - special refractory blocks, which will increase the resistance of the internal surface of the unit to thermal loads. Technical solutions and modern materials will ensure stable operation of the furnace for the next 20 years.

The expected reduction in the emission of pollutants after the repair of the furnace will be 0.2 thousand tons per year. After the completion of the accompanying reconstruction of air heaters in 2022, the total reduction in gross emissions will amount to 7.7 thousand tons per year.

Investments in the project for overhaul and modernization of the blast furnace complex amounted to more than 23 billion rubles. During the work on the site, the number of personnel reached 3 thousand people, more than 16 thousand tons of metal structures were used.

According to the plan, the equipment will reach its design capacity by the end of February.
