New roll pass design to the bar rolling process using longitudinal slitting passes

摘要

The paper presents the developed new roll pass design and a new method of rolling in slitting passes of bar with longitudinal band, which reduce energy consumption and increase durability of slitting passes compared to the methods used previously. The results of theoretical analysis were verified based on the measurements of rolling power taken during bar rolling according to the multi-strand rolling technology. Forge2007 software was employed in the numerical analysis of the process of rolling with band slitting.
