Cast iron smelted from a high scrap steel fraction and produced by carburization and the addition of ferroalloys.
The production of synthetic cast iron by means of silicon carbide as an alternative to ferrosilicon and carburization agents is characterized by a number of metallurgical effects. In combination with high scrap fractions, this not only results in process-related benefits but also an improvement in cast iron quality and added safety regarding the quality risk. Common SiC contains approx. 70% Si and 30% C. SiC does not melt but is continuously dissolved in the melt. At the same time, it is possible to achieve a certain priming effect with a long fading time (see Fading effect).
