Slit rolling - Danieli USA

Pass Design The leader sections for the multiple slit rolling pro-cess, e.g. square, rectangular or round have to be of very close tolerance. This requires: * Correct pass profile in the rolls * Correct roll gap to ensure no overfill * Correct pass alignment between top and bottom rolls * Sound roll neck bearings and positive roll

Roll Pass Design for Round Bars - ScienceDirect

The roll pass design of a whole rolling line for round bars can be carried out successfully using the actual PC. The present work examines the computer aided roll pass design of round bars. It deals with the roll pass design strategy of roughing sequences with heavy stretch and finishing sequences.
