Аннотация: Reducing gas-shrink porosity is a topical issue in the production of large slabs made of aluminum-magnesium alloys by direct chill casting. To do this, various methods of influencing the melt are used, both during the preparation and during the crystallization of slabs. Currently, due to the growing demand for slabs of large cross-Показать полностьюsections for rolling and cutting and stricter requirements for final products, research on reducing porosity is widely used in the industry. The paper presents data obtained from the study of porosity in slabs of aluminum-magnesium alloys produced by direct chill casting at the Pilot casting complex (PCC) of the company OK RUSAL. the dependence of porosity morphology on the alloy composition, size, and technological parameters of casting are presented. The main causes of porosity are considered, and metallographic images of the distribution of pores along the slab cross-section are presented. © 2021, The Minerals, Metals & Materials Society.
