SINTERING SHOP

АГЛОМЕРАЦИОННЫЙ ЦЕХ

Commissioned in 1946

Today, the sintering department operates two sintering machines, with sintering areas of 30 sq.m and 50 sq. m.

Main functions of the shop:

Main functions of the shop:

Maximum annual production:

  • Cast iron, 365 thousand tonnes;
  • Granulated slag, 115 thousand tonnes.

These activities are part of the comprehensive revamping program for the sintering & blast furnace production departments in Nadezhdinski Metallurgical Plant. In addition to replacement of the furnace housing, repair of the air heaters and other components of this installation, the furnace will be fitted with an automated process control system to improve the operating data acquisition and quickly input the required parameters. A similar system was previously installed onto Furnace No. 1 in the blast furnace shop of our metallurgical plant.

MELTING SHOP

  • smelting high-quality steel of required composition (we have mastered the production of 328 steel grades);
  • providing the large-section mill shop shop with hot ingots;
  • providing the foundry shop with steel.

Maximum annual production:

  • 756 thousand tonnes of liquid steel per year.

Before the EAF melting shop was started up, PJSC Nadezhdinski Metallurgical Plant had operated open-hearth furnaces since the plant was founded (1896). The last steel from the open-hearth furnaces was produced in October 2007. The EAF process has widened our product range and made our production technology more flexible, allowing the company to change over to other products as fast as the market demands. The last steel from the open-hearth furnaces was produced in October 2007. The EAF process has widened our product range and made our production technology more flexible, allowing the company to change over to other products as fast as the market demands.
