Pressure Die Casting Alloys are indeed to keep Magnesium at low percentage. Higher percentage Magnesium in PDC Alloys creates Embrittlement, Poor Fluidity and brittleness problem. To avoid these problems Magnesium percentage in these Alloys should be kept at a low percentage. Magnesium percentage mainly depends on Magnesium present in the recycled scrap. To reduce the magnesium to required percentage Magremover– Powder is recommended.
The addition rate of Magremover-Powder varies and depends upon the initial Level of Mg content and % of magnesium to be removed. Spread Magremover- Powder flux on the molten metal surface uniformly. During addition, rabble the Melt uniformly along-with Magremover Powder. After complete addition of flux hold material for 20 minutes in the furnace keeping the burner on low flame. After completion of reaction again rabble the melt uniformly, remove the dross and analyse the melt for Mg content, and carry out further treatment if necessary. It is recommended to add 7-10 kg Magremover Powder to remove 1 kg of magnesium from molten metal, for melt having initial Mg content 0.5% and above. To remove Mg from molten metal having lower percentage of Mg i.e below 0.4%, Magremover –Powder addition increases and it may go up to 10-14 kg to remove 1kg of magnesium from molten metal. This can be further assisted by lancing the melt with Nitrogen / Argon. Magremover-Powder can also be injected below the molten metal surface to further improve the efficiency of the treatment. However during bulk usage it is observed that the requirement of Magremover Powder varied from 8-25 kg to remove 1 kg Mg.
