FORGE AND PRESS TECHNOLOGIES

The plant includes Forge & Press Shop with production capacity 30 tons of forgings and die forgings a day.

Blank Division of the Forge & Press Shop provides blanks for forgings and die forgings production. Blanks are cut out of bars with bar shears having shearing force 800 to 1600 tons and intended for bars 55 to 230 mm in diameter.

There are drop hammers with mass of hammer bead 1,000; 2,000; 5,000 and 16,000 kg at the Division of Closed Die Forging. A wide range of drop hammers available makes it possible to produce forgings of varions shapes - from easy configuration like flanges to complicated body parts with mass 0.3 to 300 kg.

Division of Open Forging has forge hammers with mass of hammer bead 150; 400; 1,000 and 2,000 kg. Here it is easy to manufacture a wide range of forgings of round bars with mass 0.1 to 200 kg.

With the aid of universal hydraulic press having force of 1,250 tons we manufacture large - sized forgings of ingots with mass up to 4,000 kg.

At the Division of Heat Treatment structure of forged metal is ordered and stresses released.

The machinery and technology are widely used for different blanks manufacture namely:

  • Forged plates and cubes;
  • Spindles and shafts both straight and stepped;
  • Flanges and disks with ports, as well as rolled rings;
  • Body parts of various configurations.

Approximate costs per kilogramm of forgings and die forgings (without the cost of metal) are as follows:

  • Forgings of ingots - from $0.22;
  • Forgings of rolled metal - from $0.29;
  • Die forgings - $0,15.

The price of ordered products depends on the following parameters:

  • Total volume of ordered products;
  • Grade of steel;
  • Mass of product;
  • Complexity of product;
  • Kind of product and it's specification.

Terms of manufacture depending on comlexity of forgings from 10 to 20 days.

Quality Program being the component of Quality System that was established and mainained at the plant according to ISO 9001 stipulates the following operations in quality control: chemical analysis of metals, metallographic inspection of metal structure, ultrasonic and liquid panetrant examination, hardness as well as tensile and impact teeting.
