Conclusions
The nature of the distribution of specific pressure on the contact arc of roller-metal is shown experimentally.
A dependence is established for the ptessibility of powders of iron, 1Kh18N9T stainless steel and copper during vertical and horizontal rolling.
An equation is proposed, describing the dependence of densification of the powder on the maximum specific pressure on the metal-roller contact arc.
The dependence between the critical angle, the contact angle and the maximum specific pressure during vertical and horizontal rolling of iron powder is investigated, an increase in these angles being noted with an increase in pressure on the roller.
It was established that the pressibility of powders during rolling is higher than during pressing by 10–15%.
