The smelting shop is equipped with industrial-frequency induction furnaces with acid lining: unit LFD-25 having 4 crucibles, each with a 25t capacity by cast iron and two units LFD-8 having 3 crucibles, each with a 8t capacity by cast iron. 3 25t-crucibles and 4 8t-crucibles can operate at a time. The furnaces are of ASEA make.
In 2007 the shop was rebuilt resulting in equipping with a new smelting complex consisting of two mid-frequency induction furnaces, each with a 25t capacity by cast iron. The furnaces are made by INDUCTOTHERM (England).
Available are ladles 0,5t to 75t. There are two cranes for pouring with a load-carrying capacity up to 140t. The cranes can run simultaneously.
Smelted out are flake-graphite-containing cast-iron of grades СЧ10 – СЧ35 GOST 1412-85 and their analogues EN-GJL-150 – EN-GJL-350 EN 1561, nodular-graphite-containing cast-iron of grades ВЧ40 – ВЧ70 GOST 7293-85 and their analogues EN-GJS-400-15 – EN-GJS-700-2 EN 1563. Besides, available are high-alloy (up to 34% of Cr, 22% of Ni plus Мо, Si) cast iron, heat- and wear-resistant cast iron and type Ni-Hard and Ni-Resist non-magnetic cast iron.
The smelting shop ensures conveyor pouring, large- and small-size shaped casting pouring and water-jacket casting pouring.

Quality control
Castings inspection
- Castings are inspected in properties as follows:
- metal composition;
- mechanical properties;
- microscopic metallography;
- hardness on cast samples and casting surface;
- If required, also available are:
- hydraulic tests;
- ultrasonic, radiography, magnetic-particles and dye-penetrant inspections.
Quality inspection facilities
- composition is monitored with the help of quantometers ARL-31000С, ARL-272000S, ATOM-COM 181 (USA) and analyzers C and S.
- for mechanical inspection the equipment for tensile strength, bending and impact (at temperatures of –70 to +500°С) tests is used. Hardness is measured with stationary and portable instruments to Brinell, Rockwell and Vickers.
- for metallographic examination a stationary metallographic microscope Me-F3 with a magnification of 20 to 500 (Reichert-Jung, Austria) is used.
- for ultrasonic inspection portable flaw detectors are used
- for radiographic examination X-ray apparatus and accelerators are used.
- for magnetic-particles inspection a flaw detector TWM-42 (TIEDE) is available.
