Zusammenfassung:The invention relates to the industry of ferrous metallurgy, in particular to a method for producing complex reducer of killed and unkilled steels. A method for producing the complex reducer - ferrosilicoaluminium for killed and unkilled steels, which includes melting the metal charge from the secondary raw material and pouring the liquid metal into the molds of a specified standard size, where as metal charge used are metallic steel and/or cast-iron scrap, ferrosilicon sifting of quality FS45 and aluminium scrap at the following ratio of ingredients, % by weight: 10.0-75.0 aluminium scrap, 15.0-60.0 ferrosilicon sifting FS45, the rest is scrap iron, and the liquid metal is poured into moldswith ingot mass of 1.5 - 3.0 kg and it is ground into pieces of linear size to 100.0 mm. The invention provides an increase in degree of aluminium assimilation between 10.0 - 15.0 % and 30.0 % and reducing prime costs of alloys to 30.0 - 40.0 % as compared with the use of second aluminium ingots as steels reducer.
