GeneralDescription:
Cr Tablets is a new material substitute formaster alloys. It is pressed by pure metal powder and additives, according to acertain proportion after homogeneous mixing. It could adjust Cr contents of differentkinds of aluminum alloys, which could lower the melting temperature.
Applications:
1. Additives for master alloys.
2. Alloying additives for materials ofautomobile, ship building and Airspace Industries.
Advantages:
1) Simplify aluminium melting process
2) Save energy and raw materials,cost
3) Prior control alloy content, improvequality
4) high metal content, small-sized,easy tostore and use
Instructions For Use :
According to alloying element content ofalloy brand and results of bath analysis, as 95% actual yield count thequantity of Cr additive. After slagging off ,spray it to aluminum pool directlyand evenly, after flammule disappeared and 20-30minutes standing, should enhancehand stirring for 5 minutes, make it uniform diffusion. And according to actualcondition,assure some time to diffusion.
1)Use temperature:745°C±5°C
2)Quantity added(kg)=alloying element content-bathanalysis element content)X outfit furnace quantity(kg)÷actual yield 95% X additivealloying element content 3)melting time :20min-30min
