Zusammenfassung:Disclosed is an agent based on ferrosilicon for the treatment of cast iron melts before treatment with spheroidal graphite-inducing elements, especially magnesium, wherein, as additive elements, the agent additionally contains calcium, aluminum, manganese, zirconium, cerium and lanthanum. The content of iron plus silicon is at least 75% by weight with reference to the weight of all components and the elements zirconium, cerium and manganese additively are at least 5% by weight of the agent. The present invention also provides a process for the production of this agent, as well as a process for treating cast iron melts therewith.
