Effects of particle size upon the conditions of the strip shaping process in powder rolling (part II)

  • 26 Accesses

Conclusions

  1. 1.

    Experimental confirmation has been obtained of the existence of a critical particle size above which the thickness and density of strip rolled between rolls of a given diameter markedly increase.

  2. 2.

    In the rolling of granules, the size of the densification zone and the strip thickness increase as the particle size approaches the strip thickness. Under these conditions, the manner in which the particles are gripped by the rolls is analogous to that in the rolling of bulk metal.
