Abstract
In this article the problem of receiving high-quality cast strips from the magnesium alloys received by units of twin roll casting process in the combined methods is discussed. Production of sheets from magnesium alloys combination of casting and rolling at continuous giving of liquid melt to the rotating rolls is perspective and more economic method. Features of crystallization of magnesium alloys of AZ31 and AZ61 in a gap of rolls crystallizers depending on heat exchange conditions at change of technological parameters are considered. Due to impact on melt in forming system it is possible to provide formation of equal fine-grained structure of sheet hire without superficial defects. Development of the production technology of sheets from magnesium alloys creates possibility of their use of automobile branch as the facilitated details of bodies instead of the knots made of steel.
