With the ring rolling mill Siempelkamp completes its range of products for the manufacture of rings. From forging the pre-forms to manufacturing the ring blanks to ring rolling, we supply everything from a single source. Siempelkamp’s ring rolling mill manufactures seamless rings made of steel and special materials such as nickel-base, titanium, or aluminium alloys using maximum radial and axial pressing forces. The radial pressing force is hydraulically generated and applied to the part via a mandrel roll. Radial rolling is carried out by reducing the roll gap between the driven external roller and the mandrel roll. The axial pressing force is also hydraulically generated and applied to the part via the upper axial roller. Axial rolling is carried out by means of the vertical forward feed of the upper axial roller. A centring device provides for the correct position of the ring during the rolling process.
