Paper Title:
Analysis of Alligatoring Behavior during Roll Pressing of DRI Powder with Flat Roller and Indentation-Type Roller
  Abstract

A computational model for roll pressing of powder was developed based on an elastoplastic finite element method, and was applied to predict the alligatoring behavior at roll nip during powder compacting process. The yield criterion for powder has been implanted for the simulation of the roll pressing of Direct Reduced Iron powder with both flat roller and indentationtype roller. Calculated results could well explain the experimental observation that the indentationtype roller is more useful to hinder in alligatoring.
