Contact stress distribution and roll surface temperature in the roll gap analyzed with different sensors
Original language description
In this work, the contact stresses and temperatures during hot and cold rolling have been measured. A work roll containing three different sensors was used for the measurements. There were two contact devices for directly measuring forces and one temperature sensor. One sensor was the ROLLSURF sensor. Results obtained with this sensor have been presented earlier [1-3]. The measurement principle is based on deformation measurements with strain gauges which were placed on an internal cradle-type roll insert. The second sensor was a fiction pin sensor. The forces on the top of the pin were measured by three axis piezoelectric-transducers. The pin sensor was mounted inside the work roll opposite to the ROLLSURF sensor. The third sensor was a thermocouple placed next to the pin sensor. The temperatures were measured very close to the roll surface. The surface boundary conditions including the heat flux and surface temperatures were computed using inverse modelling calculations developed at Brno University of Technology. The main task of this paper is to show a comparison of the contact forces and contact length measured with the strain-gauge sensor and the pin-sensor.
