MODIFICATION OF THE ROLL PASS DESIGN TO THE BAR ROLLING PROCESS WITH LONGITUDINAL BAND SEPARATION

摘要

A new roll pass design and a new method of rolling in slitting passes of bar with longitudinal band separation have been developed within this work, which reduce the energy consumption and increase the durability of slitting passes compared to the methods used so far. The theo-retical examination results were verified based on the measurements of rolling power taken during bar rolling according to the multi-strand rolling technology. The Forge2007~R computer program was employed to the theoretical analysis of the process of rolling with band slitting
