4. Key Stages of Research

Analysis of product range of the cold rolling
mill (HPT 55).
Analysis of HPT-55’s equipment and pipes
manufacturing process.
Justification of rational technology and
facilities in process of product
manufacturing.
Calculating the calibration of HPT-55’s
working tool.
Calculation of strength and elastic
deformation of stand’s parts.

5.

Analysis of Product Range of the Mill
Od ☓ Wth = 25 ☓ 2 mm
sized pipe from the core
range was chosen for the
research.
It is manufactured out
of steel X8CrNiTi18-10
in accordance with
EN10216-5.
Calculation of rolling route
Output data:
dimensions of mother tube:
Od ☓ Wth = 57 ☓ 4 mm
dimensions of finished pipe:
Od ☓ Wth = 25 ☓ 2 mm
steel grade: 1.4878

Calculation of strength and elastic deformation of stand’s parts
The strength of roller is calculated in
three crosscuts. The following results are
obtained based on calculations:
