FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy and can be used for inoculation of grey iron or iron with globular graphite. Proposed method comprises initiation of plasma arc between the surface of said alloy and plasma torch cathode arranged in foundry distributor located ahead of mould line. Note here that said plasma torch comprises anode partially immersed in said foundry iron alloy and cathode located above the surface of said alloy to initiate plasma arc between said cathode and said surface. Note also that anode or cathode, or both comprise graphite that makes an alloy crystallisation dummy bar.
EFFECT: acceptable quality control, minimised slag formation.
