Abstract (en)
[origin: EP0439244A1] A method for the production of nodular iron is disclosed in which a nodulariser is introduced into the molten metal to be treated in at least two stages. In particular exemplified embodiments the nodularising agent is introduced in a first stage prior to entry of the molten metal into the mould cavity and, in a second stage, the nodularising agent is contained in the mould cavity or in a chamber associated therewith prior to introduction of the molten metal or the agent is added to the metal stream during its passage into the mould cavity.
