FIELD: metallurgy.
SUBSTANCE: spheroid sing modification is carried out simultaneously in several casting ladles: in a casting ladle mounted on a stand at a casting bowl, pouring metal from several intermediate ladles, in other ones- discharging metal from furnaces. The graphitising modification will be carried out simultaneously in casting bowls.
EFFECT: reduction of modification time, reduction of fraction of spherical graphite inclusions of irregular and compact shape in the casting.
