Flat-rolled product



VSMPO possesses the following equipment for manufacture of flat-rolled products: two-stand four-roll hot-rolling mill 2000, four-roll warm-rolling mill 1700, twenty-roll cold-rolling mills 1200 and 400, cutting equipment including water-jet cutting unit, descaling equipment including water-jet grinding units and sheet wet-polishing units.

VSMPO has wide heat-treatment capacities. Creep-annealing is performed for internal stress relief (no more than 30МPа) and ensure minimum non-flatness. Plates are subject to annealing in combination with creep-straightening which is performed either in bell-type electric furnaces under load generated by steel plates or in the vacuum creep-straightening unit. Plates are also subject to ultrasonic inspection.

Sheet are manufacture either by pack-rolling or by sheet-by-sheet rolling method. Pack-rolling is done in the special bay for assembly and welding of packs equipped with a number of grinding units.

VSMPO has mastered and received approval for sheet production process for subsequent super-plastic forming for aircraft structures. SPF sheets were certified by Airbus Gmbh, Airbus France, Boeing, EADS CASA.

Gas-saturated layer is removed from the surface of flat-rolled products by pickling.
