Manufacture of Ingots

VSMPO produces more than 50 grades of aluminum wrought alloys to domestic standards and more than 20 alloy grades to international standards.
Ingots are produced by semiconscious casting into open-bottom molds.

Range of cast ingots:

  • Round continuous: diameter range from 110 mm to 1180 mm (4.3-46.5 inch); length from 2500 mm to 5200 mm (8.2-17.1 feet);
  • Round hollow: outside diameter range from 272 mm to 845 mm (10.7-33.3 inch); inside diameter range from 98 mm to 200 mm (3.86-7.87 inch); length from 2500 mm to 5200 mm (8.2-17.1 feet);
  • Flat: thickness from 220 mm to 535 mm (8.7-21.1 inch); width from 810 mm to 1430mm (31.9-56.3 inch); length from 2500 mm to 5200 mm (8.2-17.1 feet);

Melt is subject to mixer evacuation and filtration through foam-ceramic filters with glass mesh to ensure extra metal purity, reduce hydrogen content, and exclude metallic inclusions.

To obtain a high quality of "as-cast" surface, casting is done in block systems with thermal filling ("hot top").
