With the cold rolling process, we produce materials with tighter mechanical properties and also tighter thickness tolerances, as well as better surface quality not achievable at steel mills.
This process consists of taking a pickled hot rolled coil and cold rolling it to the thickness the customer demands, using a combination of annealing and a subsequent skinpass process. All this allows the material ductility to enable producing almost any kind of material.
After this, the materials are slitted to the final demanded widths, they are then packaged and ready to be dispatched.
Our product portfolio is between 0.2 mm and 4.0 mm, depending on the grade, and between 10 mm and 650 mm wide.
Our cold rolling process is based on Sendzimir technology . This technology is known worldwide by its ability to roll extremely hard materials to very thin gauges, with few intermediate anneals.
Besides it’s capable of holding extremely close gauge tolerances, that are very difficult to obtain on conventional cold rolling mills.
Work rolls have small sizes, which allows higher reductions. Furthermore, because of its easy handling, they can be easily changed, ensuring the highest surface quality.
With the aim to reduce the size of the work rolls, Sendzimir rolling mills have back-up rolls to withstand the high pressures generated during rolling. The complex design of the rolls, makes possible easy adjustments for maximum flatness.
