Examination of the effect of slitting roller shape on band slitting during the multi slit rolling process

Purpose: Basing on the results of computer simulations, it will be possible to choase proper technological parameters for the slitting rollers (such as shape), which will assure the slitting of the band and verify the force parameters.Design/methodology/approach: Using FEM-based computer programs for solving the problems of the theory of plasticity enables determining the force parameters during the band separation and enabled also the determination of the tools abrasive wear.Findings: Longitudinal band separation depends on the shape of the used slitting rollers. Increasing the roller opening angle has an effect on the force parameters and on the tools abrasive wear.Practical implications: The use of commercial software applications in the design of process technologies will allow for the development of a multi slit rolling technology with a minimum number of laboratory and industrial trials.Originality/value: Using the cracking (element removal) algorithm implemented in the Forge3 program, it was possible to carry out the numerical modiling of the proces for rolling with band slitting.
