Ring rolling mill - Import export

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.

Application areas for straightening presses include the sheet metal processing industry. Here, this type of press is used for the straightening of semi-nished products, such as the levelling of uneven sheet metal and slab surfaces, which are used in subsequent processes. In addition to high straightening accuracy, Siempelkamp straightening presses provide a broad straightening spectrum and high exibility in the further processing of sheet metal. For materials with a tensile strength of 1,300 N/mm2, sheet metal with a thickness of approx. 300 mm can be processed To do so, the presses are equipped with one or several straightening rams which can be operated together or individually. The pressing force needed for straightening is applied across the entire press width. Sheet metal can be straightened by cold or warm forming with sheet temperatures of up to 600°C.
