The rolling of metal powders in a mill with a single driving roll

Summary It is shown that the distribution of specific pressures along the arc of the rolling angle on the driving roll when the other roll is idle is the same as during the rolling with two driving rolls. The distribution of specific pressures on the idle roll differs slightly in the magnitude and character of variation of the neutral angle and in the slower increase of the rolling angle with increasing maximum specific pressure. The values of the maximum specific pressure and the total pressure of the metal on the rolls are the same in the two types of rolling.A confirmation was obtained for the claim made in [1], according to which the thickness and density of strips rolled from powders in a mill with one and two driving rolls are the same.A connection was established between the rolling angle ratio and the bending of strip in the direction of the idle or of the driving roll.
