The paper discusses the technology for producing a metal sheet directly from the melt on a two-roll module and single-roll casting. The prospects and economic benefits of this method of obtaining a sheet are shown. The foreign experience of producing a steel sheet by casting between rolls is analyzed. The designs of two-roll plants of various companies and their products are examined and compared. The sheet obtained on a two-roll module is essentially a semi-finished product for further cold rolling to a thickness of 0.1 mm or less, which requires additional cold rolling. The advantages and disadvantages of the sheet forming mechanism in the roll gap, the design of the mold rolls, the material of the side stops and pouring nozzles are studied. The assortment of precision alloys that are used in a thickness of less than 1 mm is indicated. After quenching of the melt, these alloys acquire a set of unique properties that are not achievable in traditional metallurgical treatments. A comparison of the designs of industrial twin-roll and single-roll plants of various companies. The possibility of using the design of water-cooled rolls as a single-roll casting drum-cooler is shown, as well as the suitability of the side stop material for pouring nozzles when receiving the tape on the drum-cooler. The prospects of obtaining a tape of precision microcrystalline alloys of micron thicknesses directly from the melt by single-roll casting are substantiated.
