Abstract:
A Comprehensive
measurement on the force parameters of cold aluminium strip
rolling has been carried out on a 300 mm 4-h reversible cold
rolling mill. In the measurement, the width/thickness of rolled
pieces is from 15 to 620. The rolling pressure and the two
directional friction stresses in deformation zone are measured
by nine universal measuring devices arranged along the axial
direction of work roll and a sampling computer. Meanwhile, the
transverse distributions of front and back tension stresses are
measured by two flatness meters. The influence of bending roll
force (the flatness of rolled strip) on above mentioned force
parameters is investigated. The experiment provides objective
basis for the development of the 3-dimensional theory model of
cold strip rolling.
