Contact mechanics and work roll wear in cold rolling of thin strip

Simulation of cold rolling of thin strip with work roll edge contact was performed using a developed modified influence function method. Surface roughness of the rolled strip on a cold rolling mill was characterized by a surface profilometer. Roll edge contact and related surface roughness transfer...

Description
Summary:Simulation of cold rolling of thin strip with work roll edge contact was performed using a developed modified influence function method. Surface roughness of the rolled strip on a cold rolling mill was characterized by a surface profilometer. Roll edge contact and related surface roughness transfer are discussed. The focus of this work on cold rolling of thin strip was to justify the roll bite contact mechanics and to analyse the friction in the roll bite and the effect of the friction on the strip profile and the surface finish. The work roll wear and its value are also discussed. The work roll edge contact affects the work roll edge wear significantly. The strip surface finish becomes better after rolling, and the calculated rolling forces are in good agreement with the measured values.
