Heat transfer rollers, cooling rollers aare used for heating and cooling of all types of sheet products. The more precise (accurate) the temperature control and the shape of the rollers, the better the properties and quality of the sheet product.
Technologies
Our heat transfer & chill rolls are made by cast iron and on the basis of cylinders
Constructed cylinders rolls
Manufactured according the requested specifications
The basis of our cylinder rolls are tubes.The materials are steel, stainless steel, aluminium or combinations.
The quality of the weld seam is an important component for the quality of the cylinder. Therefore, welding is one of the core competences for cylinder construction. We place great value on this. Our partners are certified companies.
We build in this range: heating and cooling rollers, laminating rollers, calendars, printing rollers and embossing rolls, et cetera.
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.
Click here for more details about the casting processes.
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.
