Effect of Composition and Properties of Briquetted Powder Inoculants on the Features of Their Dissolution in a Molten Roll-Foundry Iron

  • THEORY AND TECHNOLOGY OF FORMING PROCESS
  • Published:
Powder Metallurgy and Metal Ceramics Aims and scope

The features of dissolution of briquetted powder inoculants with different compositions (92% Fe–8% Mg; 42% Fe–8% Mg–50% Cu, and 92% Cu–10% Mg) in a cast iron melt, including their densities and geometric characteristics, are investigated. It is shown that the dissolubility of briquetted inoculants in the melt decreases with increasing porosity from 8 to 15%, while increases with increasing porosity up to 30%. The introduction of copper into the composition of briquetted inoculants enhances their dissolution intensity and degree of magnesium recovery by the cast iron melt. It is established that the application of Fe–Cu–Mg inoculants provides the maximum values of graphite particles shape factor and strength properties of the cast iron at optimal temperatures (1400 and 1420°C) of melt processing.
