Description

Verfahren zur Herstellung porenfreier Metallgüsse, insbesondere von magnesiumhaltigen Legierungen, durch Einführen von Wasserstoff in das geschmolzene Metall Die Zufuhr von Wasserstoff bei der Raffination von Metall im Schmelzfluß ist bekannt. Wasserstoff zeigt sich aber in seiner Verbindungsfähigkeit viel zu träge, um mit der erforderlichen Geschwindigkeit zu reagieren.Process for the production of pore-free metal castings, in particular of magnesium-containing alloys, by introducing hydrogen into the molten one Metal The supply of hydrogen when refining metal in the melt flow is known. Hydrogen shows itself to be much too in its connectivity sluggish to respond with the required speed.

Es wurde nun gefunden, daß durch Zusätze von Metallwasserstoff, wie z. B. Silicium-, Bor-, Zirkon- oder Antimonwasserstoff, zum Wasserstoff die Reaktionsfähigkeit bedeutend verstärkt wird.It has now been found that by additions of metal hydrogen, such as z. B. silicon, boron, zirconium or antimony hydrogen, the reactivity to hydrogen is significantly strengthened.

Durch das Verfahren wird es möglich, GuBstücke verbesserter Eigenschaften zu erhalten, indem die verunreinigenden Stoffe restlos abgeschieden werden. Die Erfindung findet hauptsächlich Anwendung bei Legierungen etwa folgender Zusammensetzung: i. 8o o'o Kupfer, 2o % Magnesium, 2. 75 % Silicium, 20 % Kupfer, 5 % Magnesium.The process makes it possible to produce castings with improved properties to obtain by the contaminating substances are completely separated. the The invention is mainly used for alloys with the following composition: i. 8o o'o copper, 20% magnesium, 2. 75% silicon, 20% copper, 5% magnesium.

3. 5o °/o Aluminium, 40 % Magnesium, i o % Nickel. q.. 80 % Zink, i o % Blei; 8 % Kupfer, 2.% Magnesium usw.3.5% aluminum, 40% magnesium, 10% nickel. q .. 80% zinc, i o% lead; 8% copper, 2nd% magnesium, etc.

Bei der Untersuchung einer Legierung von 92 % Aluminum, 6 % Magnesium, 2 % Nikkel wurde bei der Behandlung mit gewöhnlichem Wasserstoff eine Zugfestigkeit des Stabes von ¢,2o5 kg/qmm und bei Behandlung unter Zusatz von Zirkonwasserstoff eine Zugfestigkeit von 17,28 kg/qmm festgestellt.When examining an alloy of 92% aluminum, 6% magnesium, 2% nickel became a tensile strength when treated with ordinary hydrogen of the rod of ¢, 2o5 kg / qmm and when treated with the addition of zirconium hydrogen a tensile strength of 17.28 kg / sqmm was found.
