Abstract
The present disclosure provides a corrugated skew rolling preparation method of a magnesium alloy bar with a gradient structure, adopts a three-roller skew rolling mill, adding a corrugated curve to a flat roll rolling section of the three-roller skew rolling mill to form a corrugated roll, the billet used is as-cast magnesium alloy bar, and steps include: simulated rolling physical experiment; rolling parameters setting; bar homogenization annealing treatment; heating treatment of bars before rolling; three-roller skew mill rolling; cooling of the rolled parts after rolling. Thus improving the preparation efficiency and preparation quality of the magnesium alloy bar with gradient structure. And further improves the formiability of magnesium alloy bar with gradient structure.
