Abstract

In the production of ingot iron and steel in which molten pig iron, adapted for the Thomas or Bessemer process, is first pre-refined in the converter and then finished in an open-hearth or electric furnace, the pre-refined metal from the converter is poured into a ladle which previously has been partly filled with pig iron, e.g. Bessemer or Thomas pig iron, the charge of pre-refined iron and pig iron, after mixing, being finally poured into the open-hearth or electric furnace. The proportion of pig iron to pre-refined metal to be mixed depends on the desired final carbon content of the iron or steel. Reference has been directed by the Comptroller to Specification 140,826, [Class 72].
