FIELD: metallurgy.SUBSTANCE: invention relates to a cast-iron manufacturing method and device. A semi-finished hot product is obtained by the reduction of an oxidised iron source with a reducing gas, and the semi-finished product is loaded into a melting unit from an accumulator or a loading device directly connected to the melting unit. With that, some part of the semi-finished product is stored in a hot state in a storage hopper before it is supplied to the accumulator or the loading device directly connected to the melting unit.EFFECT: improved efficiency of the method.19 cl, 2 dwg
