Roll manufacturing
The various conditions, in which rolls operate, require materials and heat treatments that are tailor-made for the specific application to reduce the effects of problems associated with roll forming such as roll pressure loading, rolling speed and thermal stressing.
Generally, rolls manufactured by S+C are produced using high quality tool steels. For rolls of large dimensions, powerful forging facilities ensure that there is sufficient deformation, of the forged material through to the core. We can draw on many years of experience for the selection of the optimum material.
The rolls are produced in our modern well equipped workshop on CNC high precision machines. Our experienced machinists are using the latest tooling technology enabling rolls to be machined to tight tolerances and the highest quality of finish.
Naturally, the hardening process is controlled by us; the heat treatment is matched to the steel quality and the application. Additional surface treatments can further enhance the performance of the tooling; a selection of surface treatments is available, which can be selected depending on application and/or operational demands.
Frequently used surface treatments:
- Diverse coatings (thin and thick layer)
- Hard chrome plating
- Grit blasting
- Shot peening
- Roller burnishing
- Nitriding
In addition to forged tool steels, we can also manufacture rolls from special quality iron and cast steels as well as aluminium bronzes and PM grades. Our technical staff is always on hand for technical assistance and consultation.
