Manufacture of Ingots

Electrode compaction

VSMPO-AVISMA Corporation produces ingots from CP titanium and a number of Ti alloys for both industrial and aerospace application with the diameter of up to 1150 mm and with the weight of up to 9.5 tons. There is a technical opportunity of manufacture of ingots up to 18 tons.

Round ingots are produced by double or triple VAR of compacted electrodes made by semi-continuous extrusion of charge materials on vertical hydraulic presses with the capacity of 10.000 tons. This method allows producing large solid electrodes with homogeneous chemical compound of the ingot. At this, welding of separate block is not used which prevents contamination of starting metal with gas saturated inclusions.

Charge materials contain sponge titanium, recycled scrap, master alloys and pure alloys. VSMPO-AVISMA Corporation performs 100% visual inspection of all raw materials.

Skull melting

Production of Ti ingots by skull melting is another process route employed by VSMPO-AVISMA Corporation.  Corporation has unique skull hearth arc furnaces where the metal is melted in the crucible and then poured into the non-cooled ingot mold which ensures uniform chemical composition throughout the ingot section.

VAR melting Vacuum-arc melting of consumable electrode is done in vacuum-arc furnaces. VAR furnaces possessed by VSMPO allows to satisfy the growing customer demand for Ti products and produce ingots with the diameter of 450 - 1150 mm and with the weight of up to 9.5 tons. There is a technical opportunity of manufacture of ingots up to 18 tons.

VSMPO-AVISMA Corporation melting procedures were certified by Boeing, Airbus, Rolls Royce, Pratt & Whitney, General Electric, Snecma, Honeywell. Special control programs for VAR process ensure minimum segregation non-uniformity of alloys produced.
