We supply rolls for warm rolled seamless pipes as well as form pipes, rod profiles, welding pipes and driving pipes for pipe welding devices. We optimise the roll material and the centrifugal casting process to the requirements of your specific application.
SIWACO reducing rolls manufactured out of centrifugal compound cast iron are used in areas of high thermal and mechanical demands. Whereby on a normal chilled cast iron roll it is not possible to create a pure hardness depth from over 10% of the roll diameter, using centrifugal compound cast iron it is possible to achieve a defined hardness depth. Hereby, the calibre surface is even, and wear resistant, up to the largest pipe calibres. The surface hardness can be adjusted according to your wishes.
