Abstract

An average resultant of horizontal forces in the deformation zone that defines stability of rolling process was determined as a result of analysis of experimental contact-stress diagrams. Its value is considerable under stable process and closely related to kinematic parameters, in particular, forward slip. This resultant includes a constituent related to metal strain and dynamic constituent appearing when system of particles accelerates in the area of strip and rolls contact.

Keywords: FORWARD SLIP, CONTACT STRESSES, DISTRIBUTION DIAGRAM, RESULTANT OF HORIZONTAL FORCES, DEFORMATION ZONE, DYNAMIC FORCE, STABLE PROCESS
