УДК 669.715:62-412:621.74.047 The design and technological capabilities of the multifunctional MHD-complex for the preparation of aluminum alloys and their continuous casting ingots are presented. Technology of preparing Al-2.5 wt.% Zr master-alloy in the MHD installation and continuous casting of ingots from it has been developed. It is shown that the use of electromagnetic stirring of a solid-liquid phase inside ingot during continuous casting allows to disperse the structure in aluminum master-alloys with refractory elements. Master-alloy bar was made from Al-2.5 wt.% Zr alloy ingot for continuous modification during ingot casting. The technology of medicated ingots continuous casting from high-strength aluminum alloy B96Ц1 with its modification with master-alloy bar was developed, which allowed to reduce the grain size by 3.5 times and to increase the strength of pressed products by 6% and relative elongation by 35-40%, compared to products made from continuously casted ingots of this alloy and casted without modification with overviewed master-alloy.   References 1.
