Tiruña corrugating rolls are made from solid blocks of special steel hollowed out as required by the steam chamber.
Journal welding is completed with various stress relief operations.
Rolls are induction hardened in house to a depth of 4 mm. This greatly increases the useful lifetime of the rolls with no loss of initial hardness.
Cutting the flute is one of the most critical steps in manufacturing. We dispose of a large range of state of the art machinery that guarantees the quality of the finished product.
Investment in additional machinery has enabled Tiruña to raise production to 500 sets of corrugating rolls (new and reground) plus pressure rolls and glue rolls without compromising the company’s leading position in regard to lead time and total reliability of finished products. If special finishes are required, Tiruña can supply rolls with NuChrome (for which it holds the licence in Europe) or tungsten coating.
Rolls are subjected to numerous quality-control checks throughout the manufacturing process and after completion.
Before shipping rolls, Tiruña runs them through a final operational test to check that they will perform perfectly when actually installed on the customer’s single facer.
