Deformation in and Efficiency of Rolling in Two- and Multi-Roll Passes

Resumo

For experimental evaluation of the efficiency of two-, three-, and four-directional rolling, round, square, and triangular bars made of AK6 aluminum alloy were used. It is established that the most efficient process is the four-directional rolling of square bars, which allow obtaining higher reduction without lateral flow of metal and with minimum roll force and minimum energy consumption.
