Application of the three-high skew rolling to magnesium rods production

Abstract

Abstract The main purpose of this paper was the theoretical and laboratory analysis of 20 mm AZ31 magnesium alloy rods rolled in the three-high skew rolling mill process. For this, the numerical analysis was carried out by using Forge2011® computer program. Based on the theoretical results, the distributions of stress, strain and temperature were determined. It turned out that rolling on the three-high skew rolling mill allows the rolling process to be run with high elongation factors in a single pass, which makes the skew rolling more economical and reduces the losses for roll mechanical working. After the rolling in three-high skew rolling mill, the rods of 20 mm diameter were straight, without surface defects and a low ovality.
