Abstract

Søknaden vedrører en fremgangsmåte for å kontrollere mikrostrukturen i støpejern, omfattende dannelse av en jernsmelte, fjerning av en del av smelten, tilsetning av et modifiseringsmiddel til den fjernede del av smelten og støping av den fjernede del av smelten. Modifiseringsmiddelet omfatter en komponent for modifisering av grafittfasen og en matriksstrukturmodifiserende komponent. Den matriksstrukturmodifiserende komponent kan være en perlittpromotor så som Sn eller Sb eller As eller en ferrittpromotor slik som B.The application relates to a method for controlling the microstructure of cast iron, comprising forming an iron melt, removing part of the melt, adding a modifier to the removed part of the melt, and casting the removed part of the melt. The modifier comprises a graphite phase modifier component and a matrix structure modifier component. The matrix structure modifying component may be a perlite promoter such as Sn or Sb or As or a ferrite promoter such as B.
