FIELD: metallurgy.
SUBSTANCE: in rear part of a ladle bottom, opposite its nose part, there located by means of an inclined chute depending on weight of treated cast iron is one or more molten welded tightly closed containers from steel sheets with thickness of 1.5…2.0 mm, with tightly packed spheroidising modifying agent in the form of magnesium-containing alloy combination and bulk volume of up to 10 kg; after that, the ladle is intensely filled with molten cast iron for the period of not more than 40 seconds with direction of a jet to a free part of the ladle bottom.
EFFECT: invention allows improving microstructure and mechanical properties of cast iron in castings and providing high labour capacity owing to reducing labour intensity.
