FIELD: metallurgy. SUBSTANCE: loaded charging boxes of casting machines are somewhat dried iron ore materials which are poured-on with molten cast iron. In so doing, the speed of supply of cast iron related to area of charging box cross-section to speed of motion of conveyer of charging boxes is maintained equal to (3-6):10, and sizes of iron ore lumps are selected from relation 0.025: 0.300 of charging box height. EFFECT: provision of molded charge material with uniform distribution of components ensuring their invariable composition and properties. 1 tbl
