FIELD: preparation of semifinished product used as charge material in steel melting production. SUBSTANCE: method comprises steps of charging in molds of casting plant solid filler in the form of pellets, iron ore concentrate or agglomerate; pouring first batch of melt cast iron onto filler; loading in mold disintegrated iron-carbon high-density material. Heavy material such as cast iron crumbs with size (2-50)mm does not allow filler to float. Then second batch of cast iron is poured. Received billets have content uniformly distributed in mass of filler. EFFECT: enhanced characteristics of melting. 4 cl, 1 tbl
