By means of rolling (hot and cold rolling processes) the business unit Special Metals Technology produce a multitude of sheets and strips from refractory and precious metals.
Possible dimensions:
Material strengths: > 0.06 – max. thickness on inquiry,
Strip width and tolerances depending on the material used.
An explanation / description of rolling operations at the business unit Special Metals Technology:
- Longitudinal rolling
- Flat longitudinal rolling
- Longitudinal rolling of shapes
Longitudinal rolling:
During longitudinal rolling the metal being rolled is positioned vertically to the roller shaft and moved through the gap in the rollers without ever rotating around its own axis. It is discharged in strand form from the counter-rotating rollers. The strand has a uniform cross-section and is usually classified as semi-finished. As such it is used in further manufacturing processes. According to their geometrical shape the products can be divided into planar and profiled products. Correspondingly, the tools are known as planar or profiled rollers.
Flat longitudinal rolling:
Sheets and strips from noble and base materials are generated by rolling between two almost cylindrical rollers. In order to realign the gap between the rollers (setting the strip profile), some rollers have to be honed using a special form.
Longitudinal rolling of shapes:
Long products comprise wire, rods and profiles from both refractory and precious metals plus various alloys. They are produced by rolling between anything from two to four rollers into which a gauged shape has been cut, the so-called calibre.
