Nizhny Tagil Iron and Steel Works OJSC

About the project

Facilities built in the converter shop:

An intermediate-product desulfurization unit, three ladle furnaces, a circulation vacuum degasser and four continuous casting machines. The combined capacity of the four casting machines is 4.2 million tonnes per year.

Reconstruction work was carried out on the pressing and rolling section of the wheel and tyre shop.

Reconstruction of the main process stages in wheel rolling:

• new pressing and rolling section;
• new wheel machining section;
• installation of a final wheel inspection stand.

Equipment installed in the pressing and rolling section:

• hydraulic descaling unit;
• 5,000-tonne-force hydraulic forming press;
• 9,000-tonne-force hydraulic forming press;
• DRAW 1400 vertical seven-roll wheel rolling mill;
• 5,000-tonne-force hydraulic bending and piercing press;
• marking machine;
• laser wheel measurement system;
• manipulators transferring workpieces between the main process machines.

Results of the reconstruction:

• introduction of advanced processes and equipment;
• railway wheel quality meeting international standards;
• a 1.2-fold increase in annual production to 580,000 wheels;
• a world-class railway wheel manufacturing facility, described in the source material as the most advanced in Russia, including for high-speed rail.
