SMS Completes Forging/Ring-Rolling Line for Ti Alloys

First-of-its-type production sequence gains Russian producer’s final acceptance Rings for jet engines Blanking press, a radial-axial ring-rolling machine, two ring expanders

A combination forging/ring-rolling line designed and installed by SMS Group for VSMPO-Avisma Corporation gained a “final acceptance certificate,” the contractor announced recently. The plant in Yekaterinburg, an industrial city about 900 miles east of Moscow, manufactures rings in titanium alloys for jet engine programs.

No production cost for the project has been announced. SMS announced the contract for the combination forging and ring-rolling process in 2014, calling it “the first of its kind anywhere in the world.”

SMS stated that its combination of forging and ring rolling makes it possible to produce rings with “extremely complex inside and outside profiles,” with lower material volumes

VSMPO-Avisma is an integrated mining and metallurgy group, and the world’s largest producer of titanium ingots and forged products. It has long-term titanium supply agreements in place with Boeing and Airbus, as well as jet-engine manufacturers. In recent years it has added a number of forging and machining capabilities, especially for commercial aerospace manufacturers, in addition to its titanium refining and alloying operations.

The ring-rolling operation involves a ring blank press, a radial-axial ring-rolling machine, and two ring expanders. The process manufactures titanium rings in diameters up to 3,500 mm, and up to 800 mm high.

SMS stated that its combination of forging and ring rolling make it possible to produce rings with “extremely complex inside and outside profiles,” with lower material volumes than VSMPO has required to produce similar products up to now.
