FIELD: technological processes.
SUBSTANCE: according the invention, the steel for light constructions, having a chemical compound with 15-27% of manganese, 1-6% of aluminum, 1-6% of silicon, 0.8% or less of carbon, both the rest of iron and inevitable admixtures ladle out in a preform by width d≤120 mm on the continuous casting machine with application of a foundry compound. Then divide into slabs, thus apply minerals in the foundry compound which ensure lowering of restoration speed of oxide SiO2 by the aluminum containing in a steel, and/or lowering of reached density Al2O3 by lowering of slag viscosity in a crystalliser. Immediately after the end of crystallisation and splitting of continuous preform into slabs perform alignment of temperature of a slab in the intermediate furnace located in the production line; a slab without intermediate cooling is exposed to hot cogging.
EFFECT: obtaining of high-manganese steels using continuous casting.
