Description

Verhütung der Oxydation von Metallschmelzen. Vorliegende Erfindung betrifft ein Verfahren zur Verbesserung der Metallschmelzen.Prevention of the oxidation of metal melts. Present invention relates to a method for improving metal melts.

Bekanntlich wird bei verschiedenen Metallschmelzungen, wie von Stahl u. dgl., die oberste Schicht sehr stark oxydiert, und die Oxydschicht bedeutet einen erheblichen Verlust. Durch Heraufwerfen von Magnesium wird die Oxydation verhütet bzw. eine Reeluktion herbeigeführt.It is known that in various molten metals, such as steel and the like, the top layer is very much oxidized, and the oxide layer means one significant loss. Throwing up magnesium prevents oxidation or a reeluction brought about.

Als eine erhebliche Verbesserung hat sich die Anwendung des Magnesiums in Form feiner Bänder herausgestellt. Diese Bänder haben beispielsweise bei einer Länge von i in und io in'n Breite nur ein Gewicht von i g, d. h. i g Magnesiummetall in der neuen, den Gegenstand der Erfindung bildenden Form hat eine Oberfläche von Zoo qcin, d. h. je ioo qcin oberer und unterer Fläche des Baneles. Ein Würfel, wie er von Magnesium bisher verwendet wurde, hat bei einem Gewicht von -.2 g eine Oberfläche von etwa 6o qcin. Die Überlegenheit beträgt demnach etwa das id.ofache der bisherigen An wendungsforni. Selbstverständlich ist dadurch einerseits die Ausnutzung des 'Magnesiums größer, anderseits die Reduktion vergrößert bzw. die Oxydation erheblich verringert, und der Preis beträgt nur einen Bruchteil des bisherigen.The use of magnesium has proven to be a significant improvement exposed in the form of fine ribbons. For example, these bands have a Length of i in and io in width only a weight of i g, i. H. i g of magnesium metal in the new form forming the subject of the invention has a surface of Zoo qcin, d. H. 100 qc each of the upper and lower surfaces of the banel. A cube like it was previously used by magnesium, has a surface area with a weight of -.2 g of about 6o qcin. The superiority is therefore roughly the same as the previous one Application forms. It goes without saying, on the one hand, that the magnesium is used larger, on the other hand the reduction increases or the oxidation considerably reduced, and the price is only a fraction of the previous one.

Das Magnesium wird am besten als kleine lockere Knäule von Bändern auf das schmelzende Metall heraufgeworfen, wobei es sich entzündet und durch seinen Sauerstoffverbrauch die Schmelze ihrerseits vor der Oxydation schützt.The magnesium is best presented as small loose balls of ligament thrown up on the melting metal, igniting and through its Oxygen consumption protects the melt from oxidation.
