FIELD: production of molten cast iron.
SUBSTANCE: reduced materials obtained from hot finely ground reduced iron and calcined additives from fluidized beds are delivered to at least one pair of molding rolls. They are molded for obtaining molded material having projections formed on the molded surfaces, after which they are crushed and crushed molded material is delivered to packed layer of coal where oxygen is fed for forming the molten cast iron. Molded material is molded forming acute and obtuse angles between center line formed along section in longitudinal direction perpendicularly relative to direction of molding rolls and connecting lines which connect adjacent grooves and intersect center line.
EFFECT: increased productivity; adaptability of equipment in manufacture of molded material.
