Roll shells are made of chilled cast iron, gray cast iron or forged steel, depending on the application and requirements.The more precisely the inner-Ø is honed, the better the dimensional and shape accuracy of the roll shell.
Technologies
Our roll shells are made by cast iron.
Chilled Cast Iron
Standard chilled cast rolls
The casting process for chilled cast iron and grey cast iron is using the static castic proces. The horizontal centrifugal casting is used for smaller rolls.

In this range we built: mixing rolls, thermo rolls, calender rolls, heating and cooling rolls, laminating rolls, printing rolls, refining rolls, flaking rolls, cracking rolls and embossing rolls.
