Abstract
A load transducer has been developed to measure the contact forces in the deformation
zone during rolling. The transducer consists of a strain gauge equipped insert, embedded
in the surface of the roll. The length of the insert exceeds the contact length between
material and roll. By analyzing the output from the transducer, the friction stress and
normal pressure in the contact zone can be determined. The new concept differs from
existing pin designs by a lower disturbance of lubricant film and material flow and
limited penetration of material between transducer and roll.
Aluminum, cupper and steel strips with a width of 40 mm was rolled with reduction
varying from 2.7% to 29%, in a pilot mill. For evaluating the transducer, the measured
contact forces are compared with external measurements of roll separating forces and
torque. The determined friction coefficients are compared with values found by forward
slip measurements.
