“…To test the operation of the SCCU a new Russian alloy 1580 of the Al-Mg system was used with the addition of scandium, which was studied in [27,28,[36][37][38][39][40][41][42][43][44][45][46][47][48][49][50]. The mechanical properties of the obtained deformed seminished products were studied in [27,[39][40][41][42][43][44][45][46][47][48]. Also, computer simulation was carried out to study the modes of rolling of a new alloy [36][37][38][39].…”

A physical model of a semi-continuous casting unit (SCCU) has been manufactured and tested, designed to develop a technology for casting flat and cylindrical ingots from experimental aluminum alloys for subsequent metal forming. The SCCU includes two induction melting furnaces with a tilting mechanism, a rotary mixer, a metal path system, a vertical casting machine, a jib crane, water supply, power supply, monitoring and control systems. SCCU testing was carried out on six heats of alloy 1580 of the Al-Mg system with the addition of scandium. In the first three ingots the scandium content was 0.05% (wt.). In the second series of three heats ingots with 0.075% (wt.) scandium were cast. The ingots had a high surface quality, did not have casting defects, and there were no inclusions of primary intermetallic compounds Al3(Sc, Zr) in the structure of the ingots. The bottom and runner parts of the ingots were cut off, all faces were milled and subjected to homogenization annealing in a two-stage mode: the first heating at 350 °C, 3 h, the second heating for 1 h to 425 °C, 4 h. Then the billets were hot rolled from 40 to 5 mm, annealed at 380 °C, 1 h, rolled at room temperature to a thickness of 1 mm and annealed at 350 °C, 3 h. After that, tensile mechanical properties were tested. The results of modeling ingot casting were tested in industrial conditions when casting a large ingot with a cross section of 2100×500 mm. A template was cut from the ingot with the dimensions of a billet for rolling, as that obtained from an experimental ingot cast at the SCCU. The billet was subjected to hot and cold rolling according to the conditions used for rolling the experimental ingot. At the same time the modes of heat treatment of sheet semi-finished products were also repeated. The mechanical properties of sheets of alloy 1580 rolled from experimental and industrial ingots practically did not differ. This proves the reliability of casting modes for ingots obtained at the SCCU and tested for casting industrial ingots.

“…The mechanical properties of deformed semi-nished products from alloys of the Al-Mg system, sparingly alloyed with scandium, signi cantly exceed the properties of alloys without scandium, having the same magnesium content [14, 15, 17, 19, 24, 25, 27-29, 31, 34, 35, 37, 50]. The properties are practically on the same level as industrial alloys, in which the content of scandium is 2-3 times higher [39][40][41][42][43]. Modeling of the rolling process of 1580 alloy was studied in [7,26,32,33,34,36].…”

Investigations of the rolling modes of plates from an experimental aluminum-magnesium alloy with a scandium content of 0.10-0.11 wt.%, corresponding to the chemical composition of the 1580 alloy, were carried out in laboratory and industrial conditions. It has been found that alloying of this material with scandium within the indicated limits leads to a signi cant grain re nement in the cast ingot and an increase in the strength properties of deformed seminished products. Based on the results of physical modeling of the rolling process, rational reduction modes are proposed, which made it possible to obtain deformed semi-nished products with the required level of mechanical properties. To assess the formation patterns of the metal structure necessary to obtain high-quality plates, a metallographic analysis of the structure of cast and deformed semi-nished products from an experimental alloy was carried out. The results were used to test the reduction modes during sheet rolling and to adjust the casting parameters of experimental ingots. Based on the results of the research, recommendations were formulated for the development and implementation of an industrial technology for rolling plates from alloy 1580 with a thickness of 31.5-45 mm from ingots with a thickness of 300-450 mm.
