GIB
- Metallurgical – rolled pipes from 40-72mm
- Metallurgical – rolled pipes from 30-60 mm
- Metallurgical – rolled pipes from 10-30 mm
- Metallurgical – Coil for coiling thin sheet steel
- Metallurgical – main support of electric furnace
Responsible unit
- Cold-rolling mill ХПТ55 (rolling of stainless tubes of different diameters from 30-60 mm)
Problem encountered
- When strikes occur during the rolling of cold rolled tubes (stretching of the tube), in the bearing the gap B.E.P. sharply increases as a result of the strike and sometimes the bearing suffers internal destruction, which leads to rejected tubes during rolling and sometimes to a halt in the technological process
Our solution
- The improved design of GIB 77741MESL bearings, optimised for applications with high impact loads, was installed into the rolls in the cold rolling mill. Stoppages in the rolling process were eliminated, the mill returned to normal operation. The mill’s operating time was more than 3,600 hours.
