Abstract

Metallschmelzen erhalten vielfach eine Nachbehand­ lung mit einem metallischen oder nichtmetallischen Behand­ lungsmittel. Das Behandlungsmittel kann der Schmelze auch in Drehtform zugeführt werden. Bei einem solchen draht­ formigen Mittel zum Behandeln von Metallschmelzen wird reaktives Metallpulver mit einem Eisenmetall ummantelt. Metal melts often receive post-treatment treatment with a metallic or non-metallic treatment agent. The treatment agent can also melt can be fed in rotary form. With such a wire formal means for treating molten metal reactive metal powder coated with a ferrous metal.

Zwecks Erhöhung der Reaktionsausbeute und zur Erzie­ lung eines störungsfreien Reaktionsablaufs wird eine pulver­ förmige Mischung aus mindestens einem der Metalle (A) Magnesium, Calcium und der Seltenen Erden sowie minde­ stens einem der Metalle (B) Eisen, Nickel und Mangan vorge­ sehen. For the purpose of increasing the reaction yield and for educating A powder becomes a trouble-free reaction process shaped mixture of at least one of the metals (A) Magnesium, calcium and the rare earths as well as min at least one of the metals (B) iron, nickel and manganese see.
