Abstract
The present invention describes an inoculation process for inoculating a nucleating additive to a cast iron alloy in a pouring distributor by means of using a transferred arc plasma torch, with an anode partially immersed in the cast iron alloy and a cathode located on the surface of said alloy, the anode or the cathode or both comprising graphite, preferably synthetic crystalline graphite, which supplies said nucleating additive to the iron alloy. The invention thus describes an inoculation device useful for carrying out the inoculation process.
