FIELD: metallurgy industry.
SUBSTANCE: invention refers to ferrous metallurgy, and namely to out-of-furnace processing of metallurgical melts by means of powdered reagents. Flux cored wire consists of a steel jacket and a filler containing a mechanical mixture of calcium, iron powder, and additionally, it contains granular magnesium. Content of mixture of granular calcium and iron powder, and granular magnesium in the filler, wt %, is as follows: 90.0-99.99 and 0.01-10.0 respectively. Content of filler and steel jacket, wt %, is as follows: 45-70 and 30-55 respectively. Filling factor of flux cored wire is 0.56-0.7.
EFFECT: providing effective desulphurisation of steels with high sulphur concentration without deteriorating metal fluidity, reducing deposits on the walls of pouring nozzles during continuous pouring.
