Influence of Cold-Rolled Strip Temperature on the Interference Fit of Entire Roller Embedded Shapemeter Roll

Abstract:

For entire roller embedded shapemeter roll, the temperature differences and radial relative displacements of contact node pairs on the interference fit surface between the framework’s top surface and roll body’s inner hole surface, and the sensor pre-pressure were analyzed using the finite element technology in cold reversible rolling passes. The influences of temperature differences on radius relative displacements of the contact node pairs and the sensor pre-pressure were obtained. The results show that the maximum temperature difference of the contact node pair occurs in the third rolling pass, and most of radial relative displacements of contact node pairs exceed the value of interference fit, which makes the sensor pre-pressure be close to zero. So the transfer of pressure that the strip applied on the outer surface of shapemeter roll is seriously affected, and the shape measuring signal is interrupted.
