Novolipetsk Steel Mill PJSC

Scope of work on the project: the production complex of the factory is built in the premises of the decommissioned shop of reinforced concrete products. The project provides for the reconstruction of an industrial SPCP building including performance of the following construction works:

  • construction of the impurities screening and dust exhausting plant building
  • construction of a connecting conveyor gallery of materials supply between existing buildings
  • construction of a conveyor gallery for shipping finished products to existing railways
  • construction of an electrical house buildings
  • installation of equipment in the SPCP building
  • construction of the electric cable gallery from RP-99 to the existing production building
  • lengthening of the existing railroad dock for setting wagons for loading with finished products
  • re-arrangement of existing railways by building a new tracks for passing with a useful length for 15 hopper wagons
  • laying of water and industrial sewage pipelines
  • laying of pipes for heating and compressed air
  • laying of electric cable

Information about the functional purpose of the capital construction facility:
Metallurgical briquettes are used as raw materials in the smelting of cast iron. They will be produced by extrusion from a mixture of iron-ore concentrate, dust collected in the flue gases of blast furnaces, as well as iron and carbon-containing blast furnace sludge, which are formed during wet cleaning of blast furnace gases.

Briquetting is an environmentally friendly technology with minimal environmental impact. At the factory, it is planned to install high-performance dust and gas cleaning equipment, that will ensure the purification of emissions at a level of the best available technologies (the residual dust content will not exceed 5 mg/nm3).

Launch of a new production complex will allow annually returning to production more than 250 thousand tonnes of blast furnace sludge. Consumption of iron ore pellets for cast iron production will decrease by 9% (about 580 thousand tonnes), of coke – by 3% (145 thousand tonnes). As a result, by reducing the share of expensive raw materials in the blast furnace process, the cost of cast iron will decrease by 2%.

Significance of the project: the launch of the facility will allow creating about 200 new jobs, obtaining raw materials for blast furnaces from blast-furnace wastes, reducing the cost of cast iron, and decreasing negative impact on the environment.
