Slitting Criterion for Various Slitting Roll Geometry in MSR Rolling Process

Abstract:

The main idea of multi slit rolling (MSR) technology is the capability of producing two, three, four and even five rods simultaneously from a single strip in a hot rolling process. Correct separation of the joined strips is one of the major problems in the MSR process. High tensile stresses (perpendicular to the rolling direction) are generated during movement of the band by the slitting rolls in the joining bridge. Critical value of the slitting criterion is mainly affected by geometry of the slitting rolls (angle, dimension and mass of the slitting rolls), temperature of the band and rolling speed. This paper presents results of numerical analysis of influence of the slitting roll angle on value of normalized Cockroft – Latham criterion during double slitting rolling process.
