Basic castings types:
● steam and hydraulic turbine casings;
● pump equipment casings;
● parts for press equipment (traverse, bases, anvil blocks, saddles, etc.);
● casing castings for dampers and cranes oil and gas pipelines of big diameter with different working pressure;
● parts for metallurgical and mining complexes (slag ladles of 11m3, 16m3, 16.5m3; moulds of 0.35m3, 1.25m3,
1.55m3, 1.8m3, 2.2m3; bandages; converter headpieces and throats; protection slabs for blast furnaces; running
and rack wheels; hot rolls bandages; moulds, etc.);
● other castings of different types ( including both simple and unique).
Steel-making
State of art steel melting facilities:
• 2 EAF up to 100t , 1 EAF of capacity 50t , 1 EAF of capacity 21t ;
• complex of out-of-furnace refining “ladle furnace” ;
• complex of steel vacuum treatment on the basis of mechanical pumps.
Technological process is being ruled by automated system so providing the results as follows:
• sculpture content up to 0.005%
• straightening of steel temperature according the ladle section- gradient no more than 5"C
• uniform material content in the ladle volume.
After being treated the material has the following gases content`:
• oxygen 15-25ppm
• hydrogen- max.1.5ppm
• nitrogen 50-70ppm
Forging
Presses of capacities 2000ts, 3000ts, 6000ts, 15000ts. All automated forging complexes (AFC) include
manipulators of English firm “DAVY”.
• AFC of press 3000ts has got forging manipulator of lifting capacity 30ts.
• AFC 6000ts is equipped with manipulator with lifting capacity 120ts and forging crane 300t.
• AFC of 15000ts includes manipulator of lifting capacity 170ts and forging crane of 500t.
Casting
Castings manufacturing is produced in steel-casting shop at sites:
• Large castings in caissons, castings of weight from 10-160t and up to 8.0 x 5.0 x 3.5m in size;
• At site of forming middle castings in trenches on the basis of mixer of permanent action AMD-20
• Production line LMP-75 on the basis of sand slinger, castings of weight 3030t and up to 4.5 x 2.5 x 1m in size.
Heat treatment
Technological potential of thermal production provides fdulfilment of all types of heat treatment at the forgings
and castings using volumetric and differential heating: annealing, isothermal annealing, normalization,
normalization with tempering, hardening, quenching with tempering, tempering. While carrying out the
process of hardening cooling processes are used as follows: at the atmosphere, in water, in oil, in solution
of magnesium chloride(bishophit), in water-air mixture.
Machining
Great fleet of metal-cutting and grinding equipment including turning, boring, vertical, deep boring,
plano-milling, grooving, gear milling and other types of lathes.
Quality control
This company has been in accordance with international standart requrements ISO 9001:2000 and implemented
in February2004.Control quality system has got in its disposal modern techniques that allow taking measurements
of different types: to take very accurate linear-angular measurements, to carry out non-destructive control methods
in order to detect inner and surface defects. All methods used have been certified.
Means of measuring technique are being checked and calibrated according to the valid norms.
Central works laboratory includes 7 branches: X-ray spectrum analysis laboratory, chemical analysis laboratory,
laboratory of non-destructive control methods, mechanical properties testing laboratory, metallographic inspection
laboratory, moulding material laboratory, laboratory of technological processes optimization.
Central laboratory is certified by Main organization of metrological cervices of Ukrainian Minprompolitic and is entitled
to do measurements, testing and inspection of carbon steel grades, alloyed steel grades, iron, ferrosilicium,
ferromanganese, ferrochromium, steel castings, forgings made of carbon and alloyed steel grades, forged steel
rolls for metal rolling.
