Back-up rolls for hot and cold rolling mills:
|B max||Ø 2 000 mm||B max||Ø 1 520 mm|
|LB max||unlimited||LB max||1 780 mm|
|G max||50 000 kg after preliminary machining||G max||40. 000 kg after preliminary machining|
*The above mentioned parameters refer to rough machined condition.
- Alloy steel
- Hyper-eutectoid steel
- Vacuum degassing which provides H2 content below 0,7 ppm; O2 below 25 ppm )
- We can cast ingots according to two technologies: bottom and vacuum top pouring. We guarantee great steel purity K4<30 acc. to DIN50602; sulfur content < 0,005%
- Surface hardening
We offer metallurgical rolls in rough or final machined surface condition.
Non Destructive Testing: UT
For UT we use digital defectoscope.
Our staff is very well experienced, regularly trained regarding the newest tings which appear in UT and certified according to PN EN473 with level II and III.
The certificates are issued according to the following standards:
PN-EN 10204, 2.2 and 3.1 and 3.2 (LR, GL, DNV, ABS, BV, NKK, RINA, KRS, CCS, RMRS etc.)
