SELECTED SCRAP FOR THE MANUFACTURE OF NODULAR CAST IRON PARTS
The production of nodular castings currently uses around 40% of primary ingot, in addition to the return of castings and a low percentage of scrap (5%), with the addition of alloying elements (manganese (Mn), nickel (Ni), copper (Cu)...). The ingot used is produced from iron ore (Fe), which has a very high impact on CO2 emissions and the energy required to manufacture it, as well as a higher price (around 25-35% higher than scrap). It is well known that the replacement of ingot with scrap is not an easy process due to the variability of scrap, its composition and the need to increase the percentage of inoculant required, whereby previous experiences show up to about 15% of scrap being used but only in some types of alloys.
FURESA, a manufacturer of high added-value nodular cast iron parts for various sectors, leads FUNDITREN and has collaborated with TECNALIA Technology Centre in the project implementation.
