ŽP is expanding dimension range in its portfolio

Železiarne Podbrezová is always attentive to the needs of its customers and responds to the market demand. Long-term experimental activities of employees at the Tube Rolling Mill has led to expansion of the dimension assortment of the division.

Increase of the circularity of dies and draws used at the stretch reducing mill served as the basic starting point for extension of the product portfolio. The increase of draws at the stretch reducing mill made it possible to increase the wall thickness of the entry rod and, as a result of the measures, it makes it possible to increase the length of rolled tubes and, at the same time, to increase the volume of rolled material.

It has contributed to a shift in the production line towards thicker walls, prevention of occurrence of polygon of the inner diameter and also to expansion of the product range from the viewpoint of offered tube lengths.

The adopted modifications made it possible to reduce the number of calibration series, reduce the number of stands at the stretch reduction mill, and simplify work in setting up the series and as a result of the increase of the line performance.

Thus, in total, the portfolio of rolled tubes has been expanded by 74 dimensions, including thick wall tubes with wall thickness of 14.2 mm and 16.0 mm.
